Welcome<br />

Dear Friends and Colleagues,<br />

On behalf of the Organizing Committee <strong>for</strong> the 12th Meeting of the Asian Society of Clinical Pathology and<br />

Laboratory Medicine (ASCPaLM), we take great pleasure in welcoming you to Kyoto.<br />

This is a truly international meeting with participants from all over the world, coming together to hear of the latest<br />

developments in the basic, clinical and population research into clinical pathology and laboratory medicine and<br />

associated conditions. We are sure that you’ll find the excellent program contemporary, stimulating and relevant. The<br />

state-of-the-art reviews presented by the industry-sponsored seminars will provide opportunities to bring yourself right<br />

up-to-date in the diversity of themes outside your expertise. The program incorporates a variety of presentation <strong>for</strong>mats<br />

including Plenary Sessions, Sponsored Symposia, Luncheon Seminar and Poster Sessions that have been structured to<br />

facilitate interaction and discussion.<br />

Networking with colleagues is not just limited to the scientific program. The social program is great time to catchup<br />

with friends and collaborators in a more relaxed atmosphere, while experiencing the best that spectacular Kyoto has to<br />

offer.<br />

We look <strong>for</strong>ward to seeing you during the coming month and would like to take this opportunity to thank you <strong>for</strong><br />

attending ASCPaLM KYOTO 2012.<br />

The Globalization of Medicine: Appropriate Utilization of<br />

Laboratory Tests<br />

As the borders between individual countries within the world edge “closer together” as a relationship<br />

of travel, virtual communication (virtual mail, virtual conferences, social media) and ready access to the<br />

internet and telepathology, healthcare providers are finding themselves regularly exchanging best<br />

practices as well as discussing the latest research and disease management paradigms. As medical<br />

laboratory practitioners, it is incumbent that we share best practices and also discuss which types of tests<br />

are appropriate or inappropriate to conduct, depending on the clinical scenario. Pathologists and<br />

laboratory professional are in a best position to help reduce healthcare expenditures by advising<br />

clinicians and other healthcare providers about appropriate testing. The axiom, “right test, right patient,<br />

right time and the right cost” is becoming more critical in an age of limited healthcare spending.<br />

Examples of inappropriate and over utilized tests are pervasive throughout both anatomic and clinical<br />

pathology and laboratory medicine, such as use of low-risk human papillomavirus testing <strong>for</strong> cervical<br />

cancer screening3 (proven to have no relationship to the development of cervical cancer), and the<br />

practice of unnecessary preoperative testing panels unrelated to the corresponding surgery (antinuclear<br />

antibodies testing <strong>for</strong> lupus and rheumatoid, hepatitis A and B, etc.). Another factor is the poorly<br />

characterized definitions of test use. Clinicians are often unclear about when or how to use many tests<br />

and thus may not make the appropriate choices. With approximately 4,000 new tests on the horizon over<br />

the next decade, it will be much more difficult <strong>for</strong> clinical to be kept in<strong>for</strong>med on the evidenced-based<br />

data that helps them to choose the most appropriate test, especially in the new and impending age of<br />

genomics. Unnecessary testing can also result from duplicate orders and rework, such as when a<br />

patient is transferred between heath settings without sharing of test data or when more than one<br />

physician is involved in a patient’s treatment. Research indicates there is no connection between the<br />

amount of laboratory testing done and the quality of care. Excessive testing may also lead to a chance of<br />

false positive diagnoses. Approximately 5 percent of healthy patients get abnormal test results leading<br />

to unnecessary testing and potentially risky treatments.<br />

CLINICAL PATHOLOGY SCOPE IN CANCER SURVEILLANCE<br />

Siti Boedina Kresno<br />

Dharmais National Cancer Center,<br />

Jakarta Indonesia<br />

The development of molecular biology gives us a deeper understanding of the mechanism and<br />

pathogenesis of disease and the medical science in the 21 st century will there<strong>for</strong>e be based on the<br />

understanding of disease process at molecular levels. These new trends in the field of oncology<br />

challenges clinical laboratory professionals to provide molecular diagnostic tools.<br />

Cancer surveillance considered <strong>for</strong> this presentation is not monitoring of cancer trends over time or<br />

collecting and analyzing data on cancer occurrence and risk factors at population levels, but in the<br />

context of testing people who are at increased risk <strong>for</strong> developing cancer or have previously had cancer<br />

to predict early recurrence or metastasis.<br />

The scope of clinical pathology in surveillance, prediction and prognostication in cancer includes<br />

hereditary cancer as well as sporadic cancer in particular by using lymphocytes <strong>for</strong> risk assessment of<br />

hereditary cancer and using circulating tumor cells (CTC) and or circulating or cell-free DNA/RNA in<br />

the prognostication of sporadic cancer.<br />

An Indonesian experience in this field will be presented.<br />

Liquid chromatography-tandem mass spectrometry (LC-MS/MS) has seen enormous growth in<br />

clinical laboratories during the last 10–15 years. It offers better analytical specificity than that of<br />

immunoassays or conventional high per<strong>for</strong>mance liquid chromatography (HPLC) <strong>for</strong> low molecular<br />

weight analytes and has higher throughput than gas chromatography-mass spectrometry (GC-MS)<br />

which the analyte needs to be volatile and is more time consuming by derivatization. The main<br />

applications of LC-MS/MS have been seen in the field of Drug/Toxicology and Biochemical<br />

Genetics/Newborn Screening, but in recent years there had more application in the field of<br />

Endocrine laboratories.<br />

Measures to improve specificity and sensitivity include sample clean-up and optimising<br />

chromatography to avoid interferences and ion suppression due to sample-matrix components.<br />

We will discussed our experience of LC-MS/MS in developing quantification of arecholine,<br />

melamine, ketamine, DEHP, 25(OH)D2 and 25(OH)D3.<br />

TATA-box binding protein associated factor 1 (TAF1) protein is the largest and the essential component<br />

of the TFIID complex in the pathway of RNA polymerase II–mediated gene transcription, and it<br />

regulates transcription of a large number of genes related to cell division. The neuron-specific iso<strong>for</strong>m<br />

of theTAF1 gene (N-TAF1), which we reported previously, may have an essential role in neurons<br />

through transcriptional regulation of many neuron-specific genes. In the present study, we cloned the<br />

full-length cDNA that encodes the mouse homologue of N-TAF1 (N-Taf1) protein. By carrying out of<br />

real time RT-PCR, we investigated the expression analysis of the N-Taf1 mRNA in mouse tissues and<br />

cell lines. As well as the human N-TAF1, the N-Taf1 showed limited expression in the brain and<br />

neuroblastoma, whereas Taf1 expressed elsewhere. Furthermore, in mouse embryo head or mouse brain,<br />

mRNA expression of TAF1 changes dramatically during development but N-Taf1 showed sustained<br />

expression. Our result suggests that the N-Taf1 gene has an important role in non-dividing neuronal cell<br />

rather than in cell division and proliferation during neurogenesis.<br />

Objectives: Due to increased receipt of crossmatch test requests from patients treated with rituximab<br />

desensitization therapy we aimed to optimize pronase concentration <strong>for</strong> routine testing that could<br />

significantly reduce non-specific background binding CD20 while keeping CD19.<br />

Materials and Methods: Peripheral blood mononuclear cells (PBMNC) were incubated with different<br />

concentrations (0.5; 1.0; 1.5 and 20 mg/ml) of pronase <strong>for</strong> 30 minutes at 37°C. Two kinds of normal<br />

human sera (GEN & GTI) and positive pooled serum (PPS) were used as negative and positive controls.<br />

10 µg/ml rituximab spiked NHS and rituximab treated patient’s sera were used as test samples.<br />

Anti-human CD19 and CD20 antibodies were used <strong>for</strong> phenotypic analysis.<br />

Results: 15 min incubation of donor cells with various concentrations of pronase resulted no change on<br />

CD20 expression, however extended incubation of donor cells with pronase at the dose of 1.5 mg/ml<br />

and 2.0 mg/ml <strong>for</strong> 30 min completely removed CD20 from B cell surface. The latter dose also markedly<br />

reduced CD19 expression (55%±26%, n=8) as well as its intensity. There<strong>for</strong>e, 1.5mg/ml of pronase has<br />

been chosen <strong>for</strong> further X-Match testing. MCS of rituximab spiked NHS (GEN & GTI) with<br />

un-pronased donor cells in B cell X-Match was 512±50 & 452±53 and which has reduced up to 68±28<br />

& 47±18 with 1.5 mg/ml pronase treated donor cells, respectively (n=20). Rituximab treated patients<br />

sera with un-pronased donor cells in B cell X-Match showed MCS of 445, 447 and 468 which has also<br />

reduced up to 20, 48 and 6 with 1.5mg/ml pronase treated donor cells. The pronase treatment<br />

significantly reduced non-specific background binding in both T and B cell X-Match and significantly<br />

increased sensitivity only in T cell X-Match.<br />

Conclusion: 1.5 mg/ml pronase treatment of donor cells <strong>for</strong> 30 min at 37°C could completely remove<br />

CD20 from B cell surface while keeping sufficient number of CD19 positive cells to safely X-Match<br />

INDIAN STUDY OF LIVER FUNCTION TESTS IN POST LIVER TRANSPLANT<br />

PATIENTS<br />

Liver transplantation means surgical replacement of a diseased liver with a healthy liver. The survival<br />

rate was 30% after one year. LTx was considered to be the last procedure when all medical or surgical<br />

intervention failed. Advances in donor organ preservation, surgical techniques, patient selection,<br />

immunosuppressive regimens and treatments <strong>for</strong> opportunistic infections all have contributed to<br />

substantially improve the survival rates. Despite substantial technological, medical and surgical<br />

advances, liver transplantation remains a complex procedure that is accompanied by significant<br />

morbidity and mortality.<br />

The post-operative outcome of each patient varies greatly depending on the patient’s pre- operative state,<br />

quality of the donated organ and the complexity of the surgery. Complications occur both immediately<br />

post transplant and in the long term. Most of the problems can be satisfactorily assessed with a panel of<br />

routine LFTs results of which are generated quickly, cheaply on the analyzer which operates 24 hrs.<br />

Liver Function Test identifies the presence of problem but not problem itself. Abnormal results can be<br />

meaningful only when used with clinical data, radiological findings.<br />

The study includes 75 post LTx patients in three groups Adults (Non ACR ), Pediatrics and ACR. All<br />

recipients were on immunosuppressive therapy (tacrolimus, micophenolate and Methylprednisolone),<br />

antiviral (gancyclovir), antiprotozoal, antibacterial and antifungal (fluconazole). 5 ml of blood was<br />

drawn in plain vacutainer from the post LTx patients every day <strong>for</strong> 15 days and LFT and GGT was done.<br />

Routinely per<strong>for</strong>med liver function tests correlates well with clinical complications involving liver in the<br />

transplant patients. Instead of daily testing, may be alternate day analysis of LFT should be sufficient <strong>for</strong><br />

effective monitoring of patients. The total protein and albumin and the transaminases offer little help in<br />

monitoring LFT post LTx.<br />

The elevated levels of serum GGT and ALP may be related to chronic immune damage to the<br />

transplanted liver. Serum GGT and ALP can be used as early markers <strong>for</strong> diagnosing biliary<br />

complications and can be used to asses adequacy of endoscopic treatment in the group of patients<br />

presenting early. Thus, most of the problems can be satisfactorily assed with a panel of routine LFTs<br />

generated quickly, cheaply on analyzer which operates 24 hrs each day. However, it must be emphasized<br />

that LFTs may identify the presence of problems but not the problem itself and the abnormal results are<br />

meaningful only when correlated with other clinical in<strong>for</strong>mation.<br />

Background TS is an index used to screen hereditary hemochromatosis (HH), a disease characterized<br />

by the deposition of excessive amounts of iron in parenchymal cells. Despite very low incidences of<br />

C282Y and H63D mutations, well-known common genetic causes of HH, some studies showed higher<br />

TS level in Koreans compared with those of Caucasians. This study aims to compare TS level between<br />

Korean population and the U.S. Caucasian by using the data of KNHANES V-1 and National Health and<br />

Nutrition Examination Survey (NHANES), 2001-2002. In addition, we tried to assess the existence of a<br />

familial tendency in Korean’s TS level by statistical analysis of parents’ and children’s TS value.<br />

Methods Among 8958 KNHANES V-1 subjects, those without anemia and hepatitis B antigen were<br />

enrolled in this study. The age distribution of 2946 males was 10-91 years old (mean±SD, 43.3±19.3)<br />

and 10-93 years old <strong>for</strong> 3243 females (44.6±18.6). 557 families with at least one child were included <strong>for</strong><br />

an analysis <strong>for</strong> familial tendency and total number of subjects within them was 1907.Each parent was<br />

grouped into four quartiles (designated as 1, 2, 3 and 4) based on his or her TS levels and then the mean<br />

of paternal and maternal TS four quartile indices (MTQI) were calculated and used <strong>for</strong> further analysis.<br />

Their offspring’s mean TS levels (OMTL) among each MTQI group were compared using one-way<br />

analysis of variance and post-hoc multiple comparison to show the statistical differences. NHANES<br />

2001-2002 was used to evaluate the mean TS level in Caucasian and unpaired student t-test was<br />

per<strong>for</strong>med to assess the statistical difference. We considered a p-value

Innovative Molecular Biomarkers in thrombus<br />

FDP and D-dimer: How we use them in various clinical situations<br />

Fibrin degradation product (FDP) and D-dimer are important molecular marker of coagulation and<br />

fibrinolysis, and are generated from fibrin by plasmin. Thrombin, an end product of coagulation cascade,<br />

releases fibrinopeptide from fibrinogen and thereby produces fibrin monomer. Fibrin monomers<br />

aggregate each other, and finally <strong>for</strong>m unstable fibrin. After generation of unstable fibrin, D-domain of<br />

fibrin molecules are covalently cross-linked each other by coagulation factor XIII. Finally, stable fibrin<br />

is generated. Plasmin potentially degrades any types of fibrin described above. As D-dimer is generated<br />

only from cross-linked fibrin, increasing D-dimers indicates presence of stable fibrin and its degradation<br />

by plasmin, and is useful <strong>for</strong> diagnosis of deep vein thrombosis (DVT). However, D-dimers are<br />

generated from any types of stable fibrin including fibrin in hemostasis thrombi on wound and in ascites.<br />

There<strong>for</strong>e, D-dimers are used as rule out marker <strong>for</strong> DVT. In contrast, FDPs are generated any type of<br />

fibrin including fibrin monomer and unstable fibrin. There<strong>for</strong>e, FDP sensitively responses in fibrin<br />

<strong>for</strong>mation and fibrinolysis. Also FDP increases early phase of activation of coagulation without or<br />

slightly increase in D-dimer. FDP is a useful marker <strong>for</strong> diagnosis of DIC. FDP, but not D-dimer, is<br />

potentially produced from fibrinogen. FDP increases in fibrinogenolytic condition resulting uncontrolled<br />

fibrinolysis situation.<br />

Measurement of Albuminuria (Siemens<br />

The clinical significance and measuring method of albuminuria<br />

Tsuneo Konta<br />

Department of Cardiology, Pulmonology, and Nephrology, Yamagata University School of Medicine<br />

In Japan, a number of dialysis patient keeps rising continuously, reaching more than 300,000 this year.<br />

Although diabetic renal disease alone accounts <strong>for</strong> more than 40% of the total primary disease <strong>for</strong><br />

dialysis, the early detection and prompt therapy can suppress the progress of the disease.<br />

The early stage of diabetic nephropathy does not cause any certain symptoms except moderate increase<br />

of urinary albumin excretion (“microalbuminuria”). If untreated, it can progress into macroalbuminuria,<br />

irreversibly damage the kidney and eventually lead into end-stage renal failure. Thus, the early detection<br />

of nephropathy by monitoring urinary albumin excretion is essential to treat diabetic patients.<br />

In recent years, microalbuminuria is known to exist in the majority of hypertensive patients, besides<br />

diabetic patients. Furthermore, the presence of microalbuminuria is closely correlated with the incident<br />

of cardiovascular diseases; and the decrease of urinary albumin excretion can abate these risks.<br />

However, urinary albumin is not measured adequately, even <strong>for</strong> diabetes patients, because it takes time<br />

to analyze and the frequency of its measurement is limited in Japan. Moreover, the urinary albumin<br />

concentration can be affected by body position and fluid intake. To diagnose albuminuria correctly, it is<br />

recommended to measure both albumin and creatinine levels in morning urine sample.<br />

In June 2012, a new CKD treatment guide 2012 is launched by the Japanese Society of Nephrology,<br />

recommending the use of urinary albumin/creatinine ratio <strong>for</strong> diabetic patients and urinary<br />

protein/creatinine ratio <strong>for</strong> nondiabetic patients <strong>for</strong> CKD classification. In both cases, the correction by<br />

urinary creatinine is essential to alleviate the urinary concentration.<br />

At this seminar, the clinical data will be presented, including the association between urinary albumin,<br />

kidney disease, and cardiovascular disease, and the importance of creatinine modification <strong>for</strong> the<br />

accurate evaluation of urinary albumin excretion; based on Japanese patients.<br />

Stem Cell Transplantation and Clinical Haematology Unit, School of Medical Sciences, Universiti Sains<br />

Malaysia, USM-Health Campus, 16150 Kubang Kerian Kelantan, Malaysia<br />

The hematopoietic malignancies are a diverse group of disease entities that include the lymphomas,<br />

leukemias, myeloproliferative neoplasms, myelodysplastic syndromes, plasma cell dyscrasias,<br />

histiocytic and mast cell neoplasms. Over the years multiple classification systems have been employed<br />

to provide reliable criteria in their diagnosis and their classification into clinically relevant disease<br />

entities. Earlier systems were predominantly based on cellular morphology and tissue architecture.<br />

Increased knowledge and understanding of the genetic and molecular basis of these disorders has led to<br />

continuous reassessment and refinement of the classification with incorporation of cytogenetic and<br />

molecular genetic analyses as part of the diagnostic criteria. In this talk I will discuss changes and<br />

issues regarding the revised World Health Organisation (WHO) classification of hematopoietic and<br />

lymphoid neoplasms. The integration of molecular in<strong>for</strong>mation together with morphology,<br />

immunophenotype and clinical in<strong>for</strong>mation has helped to further refine the WHO classification and<br />

improve its prognostic value. Illustrative examples, with an emphasis on the myeloid neoplasms will<br />

be presented.<br />

Challenges of Cytogenetics &FISH Diagnosis in Leukaemias and Lymphomas<br />

All human DNAs including the genes are neatly packed into 46 chromosomes, 22 pairs of autosomal<br />

chromosomes and one pair of sex chromosomes. Cytogenetics is a branch of genetics that is concerned<br />

with the study of chromosomes. When combined with molecular techniques such as Fluorescence in-situ<br />

Hybridization (FISH), cytogenetic analysis has widespread clinical applications in the diagnosis of<br />

leukaemias and lymphomas.<br />

Cytogenetic studies and FISH are now offered as a standard of care in the diagnosis of patients with<br />

leukaemia and lymphoma. However, there are challenges with the use of these two diagnostic tools and<br />

their limitations will be discussed. Improved processes and techniques including slide dryer chamber<br />

and metaphase finder are employed to enhance the efficiency and to improve turn-around times.<br />

In leukaemias and lymphomas, cytogenetic study plays a significant role in the detection of abnormal<br />

neoplastic clones, classification of malignant disorders, prediction of disease progression, monitoring<br />

response to treatment, detection of minimal residual disease and institution of targeted therapy, notably<br />

chronic myeloid leukaemia (CML). Molecular targeted drugs and the treatment outcome in CML will be<br />

illustrated. Various recurring chromosomal aberrations in acute and chronic leukaemias as well as<br />

lymphomas have been found. In bone marrow or stem cell transplantation, cytogenetic is used to<br />

determine engraftment or chimerism and to assess disease remission or relapse. FISH strategies using<br />

various fluorescent-labeled DNA probes including FISH panel testing enhance the usefulness of<br />

cytogenetic analysis of leukaemias and lymphomas. Other strategies include comparative genomic<br />

hybridization (CGH) arrays and multi-colour FISH (M-FISH).<br />

Any new discovery of more specific genes and recurring chromosomal aberrations in leukaemias and<br />

lymphomas in conjunction with the availability of targeted FISH probes will enhance the diagnosis of<br />

leukaemias and lymphomas which may lead to better risk stratification and more concise molecular<br />

targeted therapy in future.<br />

4) Age-specific reference intervals: derivation <strong>for</strong> pediatric population from the hospital in<strong>for</strong>mation<br />

system.<br />

Jeong-Ho Kim, MD & PhD (Republic of Korea)<br />

Although global ef<strong>for</strong>t led to standardization of many of the common laboratory tests, their reference<br />

intervals (RI) remain widely variable amongst laboratories. This reflects difficulty in deriving RIs by<br />

individual laboratories and highlights the necessity of deriving it collaboratively <strong>for</strong> common use. The<br />

guidelines used <strong>for</strong> defining, establishing and verifying RIs are available, which was published by CLSI<br />

in collaboration with IFCC. There is a strong global need <strong>for</strong> establishment of proper RIs <strong>for</strong> common<br />

use by conducting multicenter studies. However, there remain controversies on various aspects of<br />

conducting the study.<br />

In this symposium, Prof. Ichihara presents the common protocol <strong>for</strong> the global multicenter study on<br />

RIs, which is proposed as well as currently being conducted by Committee on Reference Intervals and<br />

Decision Limits (C-RIDL) of IFCC. In order to validate the protocol, the following aspects will be<br />

discussed: 1) criteria <strong>for</strong> recruitment of healthy volunteers, 2) ways of controlling pre-analytical<br />

variables, 3) harmonization of results across collaborating countries based on common measurements of<br />

a panel of sera, 4) methods <strong>for</strong> secondary (posteriori) exclusion based on test results, 5) transference of<br />

the established RIs based on a “mini panel” of sera.<br />

Dr. Ishikura, a member of C-RIDL, will present an overview about the feasibility of the panel-of-sera<br />

strategy in harmonizing results worldwide, and will also discuss the possible use of mini-panel in the<br />

transference of established RIs.<br />

Dr. Shah and Dr. Ashavaid will talk on the controversies over the use of parametric or nonparametric<br />

computation of RIs and secondary exclusion of individuals after obtaining testing results. The issues<br />

based on the simulation study will also be discussed.<br />

Prof. Kim will talk about the difficulty in establishing RIs <strong>for</strong> the pediatric, and geriatric population.<br />

He will review the issue in the literature and will present his approach in selecting appropriate reference<br />

individuals from large hospital records <strong>for</strong> deriving the pediatric RIs,<br />

With this overview, we would like to rationally discuss the optimal ways of establishing the RIs at the<br />

University College of Medicine, Korea<br />

Background: Defining pediatric reference intervals is one of the most difficult tasks <strong>for</strong> laboratory<br />

physicians. The continuously changing physiology of growing children makes their laboratory values<br />

moving targets. In addition, ethnic and behavioral differences may also cause variations. Age- and sexspecific<br />

partitioned reference intervals of 13 serum biochemical analytes in Korean children were<br />

presented.<br />

Methods: A total of 2,474 patients, girls from 2 to 14 years and boys from 2 to 16 years, tested in a<br />

short stature workup but diagnosed as normal at the pediatric endocrinology clinic of Severance<br />

Hospital from Sep 2010 to Jun 2012 were included in this study. Calcium, inorganic phosphorus, blood<br />

urea nitrogen (BUN), creatinine, uric acid, glucose, total cholesterol, total protein, albumin, alkaline<br />

phosphatase (ALP), aspartic aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin<br />

test were per<strong>for</strong>med on Hitachi 7600 analyzer (Hitachi High-Technologies, Tokyo, Japan). Partitionings<br />

<strong>for</strong> gender or age group were per<strong>for</strong>med by ANOVA, Mann Whitney test, Harris and Boyd method<br />

(Clin Chem 1990;36:265-70), and Lahti criteria (Clin Chem 2004;50:891-900).<br />

Results: Age specific partitioned reference intervals <strong>for</strong> ALP, creatinine, and total bilirubin in both<br />

genders could be established. In addition, age specific partitioning of AST in female and total protein<br />

and uric acid in male was required. However, age or gender partitioning of calcium and albumin in<br />

children was not required.<br />

Conclusions: Age and gender specific partitioned pediatric reference intervals of 13 clinical chemistry<br />

assays derived from Korean healthy children per<strong>for</strong>med in pediatric endocrinology clinic could be<br />

established.<br />

Background- Evidence from in vitro studies indicates that small dense LDL (sd-LDL) is more<br />

atherogenic than large buoyant LDL (lb-LDL). Furthermore, circulating levels of sd-LDL are highly<br />

correlated with triglycerides and are increased in individuals with an atherogenic lipoprotein profile<br />

such as patients with diabetes and metabolic syndrome. Previously, sd-LDL has been associated with<br />

risk <strong>for</strong> vascular disease. However, the lack of a standardized sd-LDL assay which can be per<strong>for</strong>med in<br />

routine clinical laboratories has hampered its clinical application.<br />

Objectives- We recently examined the relationship between plasma sd-LDL-cholesterol (sd-LDL-C)<br />

level and risk <strong>for</strong> incident coronary heart disease (CHD) and stroke in the ARIC cohort.<br />

Methods- Plasma sd-LDL-C was measured in 11,419 men and women of the biracial ARIC study using<br />

a newly developed automated homogeneous assay. A proportional hazards model was used to examine<br />

the relationship between sd-LDL-C, vascular risk factors, and risk <strong>for</strong> CHD events and stroke over a<br />

period of ≈10 years.<br />

Results- Mean plasma sd-LDL-C was higher in Caucasians than in African Americans (45.2 vs. 37.4<br />

Abbott Laboratories, 100 Abbott Park Road, D-09GN, Bldg. AP20, Abbott Park, IL 60064-3500 USA<br />

The high level of genetic diversity characteristic of Human Immunodeficiency Virus Type 1 (HIV-1) has<br />

significant implications <strong>for</strong> diagnosis, screening, vaccine development, and patient monitoring.<br />

Phylogenetic analysis has revealed four distinct lineages or groups of HIV-1, designated as groups M, N,<br />

O and P. Group M strains are further subdivided into subtypes A-D, F-H, J and K. For env, sequence<br />

differences between subtypes and groups of HIV-1 range from 15-25% to 50%, respectively.<br />

Recombination greatly increases overall diversity. Currently, more than 51 circulating recombinant<br />

<strong>for</strong>ms and a myriad of unique recombinant <strong>for</strong>ms have been identified; recombinant strains constitute<br />

>20% of worldwide HIV-1 infections. Recognizing the implications of HIV-1 diversity, the Abbott<br />

HIV-1 Global Surveillance <strong>Program</strong> was established. Goals of this comprehensive program include:<br />

monitoring global diversification of HIV-1, identifying newly emerging variants, and development of<br />

panels of genetically and geographically diverse specimens. Studies advancing our understanding of<br />

HIV-1 diversity will be presented. Globalization, growing numbers of immunocompromised patients,<br />

and environmental changes have fueled a need <strong>for</strong> techniques to detect novel or previously unrecognized<br />

pathogens. Recent advances in metagenomic technologies have trans<strong>for</strong>med virus discovery. The<br />

UCSF-Abbott Viral Diagnostics and Discovery Center represents one of few laboratories in the world<br />

that leverages both pan-viral DNA microarrays (Virochip) and high-throughput sequencing <strong>for</strong> viral<br />

discovery and screening. Both technologies offer a unique opportunity to screen in a non-biased<br />

manner <strong>for</strong> all known viruses as well as <strong>for</strong> unknown viruses. Recent advances in application of these<br />

metagenomic tools will be discussed. Advancement of these technologies offers unprecedented<br />

opportunities <strong>for</strong> pathogen discovery and diagnostics.<br />

Introduction : the PLEX-ID technology (Abbott Ibis Biosciences), combining broad-range multiwell<br />

PCR and mass spectrometry enables the detection and identification of a large spectrum of pathogens in<br />

a single test. The PLEX-ID analysis is based on a broad multiwell PCR followed by an electrospray<br />

ionization of the generated amplicons to analyse their time of flight by mass spectrometry. The weight<br />

of the amplicons allows to determine their base compositions. The PLEX-ID technology allows to<br />

identify large a variety of pathogens from various sample types (blood, plasma, biopsy, CSF, BAL..) in a<br />

few hours, enabling the resolution of mixtures and according to the assay, a high resolution in<br />

genotyping. A large panel of assays is available, from public health and biothreat to medical diagnostics.<br />

That integrated solution allows the analysis of up to 15 x 96-well plates over 12 hours <strong>for</strong> a total<br />

throughput of up to 250 samples per day.<br />

We evaluated in our university hospital, specialized in Hematopoietic stem cells (HSC) and kidney<br />

transplants, the per<strong>for</strong>mances and reliability of the PLEX-ID technology.<br />

Objectives : to compare the accuracy and the rate of infections detected by PLEX-ID clinical assays and<br />

routine standard methods and to compare the turnaround times of both procedures.<br />

Methods : We evaluated 3 different clinical PLEX-ID assays <strong>for</strong> medical microbiology.<br />

- The Viral IC assay detects 174 RNA and DNA viruses species and 2611 subspecies. We first analyzed<br />

275 frozen samples from 54 children and 11 adults infected with Adv (245) and from non-infected<br />

patients (30). In a second study, we parallelized the routine vs PLEX-ID in 79 fresh samples from HSC<br />

and kidney transplants.<br />

- The BAC Detection assay identifies 6026 species of bacteria and Candida and 4 antibiotic<br />

resistance markers ( kpc, mec A, van A, van B). Peripheral blood and catheter sampling were tested in<br />

BACT Alert blood culture (bioMérieux) and PLEX-ID. Preliminary study included 48 samples from<br />

adult patients.<br />

- The Broad Fungal assay identifies 2108 species. Fresh broncho-alveolar lavages and nasopharyngal<br />

aspirates from 25 patients were compared between fungal culture and PLEX-ID analysis.<br />

Additional samples collected from patients with undiagnosed fever were included in the BAC and<br />

Fungal studies.<br />

Results : All the negative PLEX-ID results in clinical samples were negative in the routine procedure<br />

considered as the gold standard, pointing the excellent PLEX-ID negative predictive value. A high<br />

negative predictive value was also observed with stored plasma samples in Viral IC assay.<br />

- Viral IC assay in Adenovirus-infected patients: ADV was detected in 96.4% of ADV positive stored<br />

plasma. The accuracy <strong>for</strong> species identification was 0.985. Out of 29 routine-negative samples collected<br />

from known ADV infected patients, 7 were positive with PLEX-ID. Viral loads determined with<br />

Tacrolimus in Adult Renal Transplant Recipients<br />

Pradeep Naik, Mallikarjuna Madhavarapu<br />

Department of Clinical Biochemistry, Global Hospitals, Lakdikapool, Hyderabad-500004, India<br />

Background<br />

Success of an immunosuppressive drug therapy depends on extent of exposure to the drugs (the blood<br />

levels and duration) which is measured as area under the curve (AUC). Tacrolimus also shows<br />

considerable variability in its pharmacokinetics, with poor correlation between Tacrolimus trough level<br />

and systemic exposure, as measured by the area under the curve of concentration time. Monitoring<br />

trough levels helps not only in reducing nephrotoxiicity but also the chances of acute rejection; even<br />

though there is no international consensus, the trough concentration is used to determine dosing and the<br />

AUC <strong>for</strong> calculating the exposure of the patient to the drug. The major objective of this study was to<br />

find the best sampling time <strong>for</strong> an abbreviated AUC0-6 (area under the concentration time curve) to<br />

predict the total body exposure to Tacrolimus in adult renal transplantation recipients.<br />

Methods<br />

The study involved retrospective analysis of 14 renal transplant patients (2 female+12 male) who were<br />

on triple immuno suppressive therapy, methyl prednisolone, mycophenolate mofetil and Tacrolimus.<br />

Blood samples were collected be<strong>for</strong>e administering Tacrolimus (0 h) to determine trough concentration<br />

and at fixed time points of 2h, 4h and 6h after administration of oral Tacrolimus and analyzed<br />

induplicate by micro particle enzyme immunoassay. AUC0-6 was determined using the linear trapezoidal<br />

rule. Association between the blood concentration and AUC6 were evaluated by Pearson correlation<br />

coefficient. All statistical analyses were per<strong>for</strong>med using SPSS software program.<br />

Results<br />

The trough levels were fairly consistent at 7.9-18 ng . h/mL in all the patients included in this study and<br />

this did not show variation with age or sex. The AUC0-6 was higher (202-290 ng/mL at 3-8 mg Bis-Daily<br />

(BD) dosage) in patients who received kidney from cadaver compared to recipients from live donors<br />

(60.5-171 ng/mL at 3-8 mg BD dosage) but whether the clinical significance of this is not known.<br />

Highest AUC0-6 was 246 ng/mL observed at 4.5 mg BD dosage. Dosages higher than 2 mg BD did not<br />

result in noticeable increase in AUC0-6. Peak blood levels of Tacrolimus were obtained 4 h after<br />

administration<br />

Conclusion<br />

Trough level determination and C2, C4 two-point limited sampling strategy may be useful to plan the<br />

dosing strategy and estimate exposure of renal transplant patients to Tacrolimus.<br />

Macrophages play a major role in the development of vascular lesions in atherogenesis. The cells<br />

express FcγRIIIa (CD16) identical to that in NK cells, but with a cell type-specific glycosylation, and<br />

these soluble <strong>for</strong>ms (sFcγRIIIa) are present in plasma. We measured sFcγRIIIa Mφ derived from<br />

macrophages in plasma with anti-FcγRIIIa Mφ monoclonal antibodies and found that the levels of<br />

sFcγRIIIa Mφ were related to the severity of coronary atherosclerosis in patients with coronary artery<br />

diseases (CAD).In volunteers, the sFcγRIIIa Mφ levels measured at the annual medical checkup were<br />

related to the number of risk factors <strong>for</strong> atherosclerosis and were correlated with carotid maximum<br />

intima-media thickness (IMT). In the present study, we measured sFcγRIIIa Mφ in plasma from patients<br />

examined with carotid artery echography. The levels of sFcγRIIIa Mφ , but not the sFcγRIIIa, were<br />

significantly increased in patients examined with carotid arterial echography, compared with<br />

age-matched healthy controls. Patients with echogenic/echolucent plaques or mixed with<br />

echogenic/echolucent and calcified plaques had the higher sFcγRIIIa Mφ levels, but patients with only<br />

calcified plaques had levels similar to patients with no plaque or intact carotid artery. The levels of<br />

sFcγRIIIa Mφ were correlated with maximum plaque diameters, especially in patients with<br />

echogenic/echolucent plaques. Because unstable plaques contain a lot of lipid and macrophages inside,<br />

the sFcγRIIIa Mφ may serve as a novel risk biomarker <strong>for</strong> unstable angina or myocardial infarction.<br />

The Role of S100B Protein and GFAP in Predicting Discharged NIHSS of Anterior<br />

Circulation Ischemic Stroke<br />

Yenny Surjawan, Suryani As’ad, Teguh A.S Ranakusuma, Andi Wijaya<br />

Medical Faculty of Hasanuddin University, INDONESIA<br />

Background: Patient with larger ischemic lesion will suffer more severe neurological deficit. Lesion<br />

size measurement by MRI is still limited. Another approach pursued through examination of markers<br />

released by damaged brain cell. S100B protein and GFAP, markers of damaged brain cell, had been<br />

reported to have an association with stroke. This study aimed to know whether both markers could<br />

estimate the discharged NIHSS of anterior circulation ischemic stroke.<br />

Methods: This observational prospective study was per<strong>for</strong>med on 74 anterior circulation ischemic<br />

stroke patients. S100B protein and GFAP were measured by ELISA.<br />

Results: A significant difference was found in S100B protein concentration between mild and not mild<br />

discharged NIHSS (p < 0.05). S100B protein concentration showed a significant correlation with<br />

discharged NIHSS (r = 0.488; p = 0.000). An equation was yield to predict the risk and probability to get<br />

a not mild discharged NIHSS by S100B protein (OR = 1.009; 95 % CI 1.0003 - 1.0188; p = 0.044).<br />

S100B protein at 78.3215 ng/l produced a 66 % sensitivity and 70 % specificity, with positive and<br />

negative predictive value of 76 % and 58 %, respectively (AUC = 73.9 %, p = 0.001, 95 % CI: 62.7 % –<br />

85.2 %). There was a significant difference in the proportion of subjects with low and high GFAP in<br />

either not severe or severe group of NIHSS at discharge (p = 0.008).<br />

Conclusion: S100B protein measured at 48 to 72 hours after onset could predict the risk and probability<br />

to get a not mild discharged NIHSS in anterior circulation ischemic stroke patients. No subject with low<br />

GFAP level showed a severe NIHSS at discharge.<br />

Central Scientific Research Laboratory, Nat’l Institute of Medicine, Mongolia<br />

Objectives: Mass screening of hereditary abnormality of phenylalanine metabolism in newborn as<br />

essential test procedures in many countries request evaluate feasibility of low cost microbiological test<br />

in screening of children in the country with less developed infrastructure.<br />

Materials and Methods: Blood samples were collected from 620 pupils studied at specialized school<br />

№29 of Ulaanbaatar with clinical diagnosis of mental deficiency, different <strong>for</strong>ms. Genetic defect of<br />

phenylalanine metabolism was investigated by Guthrie test, based on competition between the amino<br />

acid Phenylalanine and inhibitor <strong>for</strong> phenylalanine ß-2-Thyenilalanine, kindly provided by WHO<br />

country representative from supplier Difco laboratories inc, 920 Henry Street, Detroit, MI 48201-2532.<br />

Results: Phenylketonuria (PKU) is a recessive hereditary disease, with estimated frequency of<br />

1:10.000. Patients have deficient hepatic enzyme Phenylalanine-hydroxylase, which catalyzes the<br />

conversion of Phenylalanine to Tyrosine and consequently an increase of Phenylalanine in blood and an<br />

increase of Phenylpiruvic Acid in urine (PKU), which causes a mental deficiency in new-born infants. A<br />

possibility to avoid mental damages is feeding new-born babies with a Phenylalanine free diet from the<br />

first weeks of life. Mass screening of PKU is not introduced in the country yet. There<strong>for</strong>e cost efficient<br />

screening test to diagnose PKU is very useful since it gives a chance to prevent any mental damage. Of<br />

the 620 investigated children (285-girls, 345- boys within the age of 8-18) positive results were obtained<br />

in 10 mentally retarded children (1.63%).<br />

Conclusion: 1. Microbiological method of Guthrie is semi-quantitative determination of phenylalanine<br />

in the blood and characterized by high sensibility and reproducibility and feasible test <strong>for</strong> screening of<br />

children in countries with limited resources. 2. The prevalence of positive results was almost 2 and half<br />

times more in comparison to the results of <strong>for</strong>eign investigators, where used biochemical urine test and<br />

where PKU is revealed in 7 of 1125 mentally retarded patients (0.6%).<br />

Dept. Medical Care Policy Implementation and Coordination, MOH, Mongolia<br />

Objectives: The main objective of NEQAS in Mongolia is to provide an educational support towards<br />

improvement of clinical chemistry laboratory diagnostic services and participation is voluntary and<br />

confidential, though State Inspectorate makes participation obligatory <strong>for</strong> both governmental and private<br />

laboratories.<br />

Materials and methods: Lyophilized commercial QC materials <strong>for</strong> 20 parameters and structured report<br />

<strong>for</strong>mat distributed to the participants monthly and the Scoring System (Bullock & Wilde, 1985) used <strong>for</strong><br />

calculation. The system depends on number of related indices such as Variance index score (VIS), the<br />

difference, between the result returned and the designated value, expressed as a percentage of the<br />

designated value, divided by the chosen coefficient of Variation (CCV) <strong>for</strong> the analyte, expressed as<br />

percentage, and OMRVIS, the mean of the 40 most recent variance index scores irrespective of analyte<br />

<strong>for</strong> each laboratory.<br />

Results: CSRL, NIMM, approved by the Health Minister, Mongolia as principal organizer of the<br />

NEQAS and reflects the WHO recommendations on EQAS design and purpose and the scheme provide<br />

assessments of the state of the art (general per<strong>for</strong>mance) of both individual laboratories and countrywide<br />

services and the effects of individual analytical procedures (method principles, reagents and<br />

instruments). Doubled decrease (improvement) of countrywide OMRVIS achieved in 2011since 2000<br />

(from 320 to 160) and dramatic decrease of MRVIS observed in individual best laboratories during this<br />

period of time (from 220 to 55).<br />

Conclusions: System of Clinical Chemistry NEQASs of Mongolia has been introduced since over more<br />

than 20 years and its usefulness is supported by the remarkable evidence of slow but continuing<br />

Oxidation of cholesteryl esters in lipoproteins by reactive oxygen species yields cholesteryl ester<br />

hydroperoxides (CEOOH). In this study, we developed a novel method <strong>for</strong> identification and<br />

characterization of CEOOH molecules in human lipoproteins by use of reversed-phase liquid<br />

chromatography with an hybrid linear ion trap–Orbitrap mass spectrometer (LC–LTQ Orbitrap).<br />

Electrospray ionization tandem mass spectrometric analysis was per<strong>for</strong>med in both positive-ion and<br />

negative-ion modes. Identification of CEOOH molecules was completed by use of high-massaccuracy<br />

(MA) mass spectrometric data obtained by using the spectrometer in Fourier-trans<strong>for</strong>m (FT) mode.<br />

Native low-density lipoproteins (nLDL) and native high-density lipoproteins (nHDL) from a healthy<br />

donor were oxidized by CuSO4, furnishing oxidized LDL (oxLDL) and oxidized HDL (oxHDL). No<br />

CEOOH molecules were detected in the nLDL and the nHDL, whereas six CEOOH molecules were<br />

detected in the oxLDL and the oxHDL. In positive-ion mode, CEOOH was detected as [M + NH4] + and<br />

[M + Na] + ions. In negative-ion mode, CEOOH was detected as [M +CH3COO] − ions.<br />

CEOOH were more easily ionized in positive-ion mode than in negative-ion mode. The LC–LTQ<br />

Orbitrap method was applied to human plasma and six species of CEOOH were detected. The limit of<br />

detection was 0.1 pmol (S/N=5:1) <strong>for</strong> synthesized CEOOH.<br />

An approach to chemical education at medical technologist training institutions in<br />

Japan<br />

Hidetusgu Kohzaki<br />

I teach chemistry at a medical technology school (1, 2, 3, 4). Chemistry is not necessarily the favorite<br />

subject of Japanese students receiving paramedical education (1). However, many biochemical,<br />

microbiological, and advanced genetic tests (3, 4) are per<strong>for</strong>med in the medical setting, and solutions<br />

and media also have to be prepared. Nurses and paramedics including medical technologists rarely<br />

prepare solutions because of automation in the medical setting and a lack of time. However, they might<br />

feel uneasy about certain aspects of medical practice, such as the use of infusions and injections, if they<br />

do not know how to prepare and label solutions. In addition, the annual national examinations include<br />

questions on concentration calculations. In this article, I introduce our approach to providing chemical<br />

education <strong>for</strong> medical technologists.<br />

Ethanolamine (EA) is mainly hydrolyzed from phosphatidyl ethanolamine (PE) by phospholipase D<br />

(PLD) in vivo. A study reported that urine EA increased in newborns as Zellweger syndrome, a<br />

congenital metabolic disease, but its concentration in blood and clinical significance in adults were not<br />

clarified. Recently, a metabolomics study using mass spectrometry reported that EA in saliva of<br />

pancreatic cancer patients increased significantly. There<strong>for</strong>e, our purposes are to develop a rapid and<br />

simple enzymatic method with an amine oxidase involving copper from Arthrobacter sp. (AAO) (EC<br />

1.4.3.6) and to examine the clinical meaning of EA in serum. In our measurement method, reagent 1<br />

(R-1) contained 0.1 mol/L HEPES buffer (pH 8.2 at 25ºC), 1.6 mmol/L TOOS, 5.0 kU/L POD, 1.12<br />

mmol/L N-ethylmaleimide, 16.8 kU/L L-ascorbate oxidase (ASOD) and 7.47 mmol/L NaN3. Reagent 2<br />

(R-2) contained 0.1 mol/L HEPES buffer (pH 8.2 at 25ºC), 20.0 kU/L AAO and 0.4 mmol/L<br />

4-aminoantipyrine. The assay used a Hitachi 7170 type analyzer. A 10 µL specimen was mixed with 180<br />

µL R-1; after incubation <strong>for</strong> 5 min at 37 ºC, 90 µL R-2 was added; after another 5 min, the mixture was<br />

measured using a 2-point end assay per<strong>for</strong>med at 37 ºC, with wavelengths of 700/546 (sub/main<br />

wavelength). The within-run CVs of the present method with three kinds of EA solutions ranged<br />

0.43-7.13% (n=10). The standard curve showed linearity from 0 to 800 µmol/L. Analytical recovery was<br />

98.4%. The reference interval of EA in normal was 8.17 ± 4.83 µmol/L (n=19). EA in hepatocellular<br />

carcinoma patient sera was significantly higher than normal. In conclusion, our method <strong>for</strong> serum EA is<br />

suitable <strong>for</strong> routine clinical use in the laboratory <strong>for</strong> determination of accuracy and simplicity. We<br />

consider EA in serum may be a new biomarker of hepatocellular carcinoma.<br />

Background: The Tamm-Horsfall protein (THP) is a 80–90 kD glycoprotein synthesized in the thick<br />

ascending limbs of the Henle’s loop in the kidney. Upregulation- or downregulation of this protein’s<br />

expression is observed in patients with several renal diseases. THP aggregates with itself or other<br />

urinary components. To dissociate this, the assay procedures require urine samples be highly diluted<br />

(>100-fold). There<strong>for</strong>e, we aimed to develop a highly sensitive enzyme-linked immunosorbent assay<br />

(ELISA) <strong>for</strong> determining urinary THP levels, and investigated the usefulness of measuring urinary THP<br />

levels in diagnosing renal dysfunction.<br />

Methods: THP was purified from pooled urine samples of healthy subjects by per<strong>for</strong>ming diatomaceous<br />

earth filtration. This THP was used as an antigen in mice to raise monoclonal antibodies by using classic<br />

hybridoma techniques, and used <strong>for</strong> the capturing of the antibody in the ELISA. Polyclonal antibody<br />

was also raised in rabbits, and used <strong>for</strong> the detection antibody. We analyzed 25 samples from untreated<br />

patients with different kinds of glomerulonephritis and age-matched healthy subjects. The urine samples<br />

were diluted to ~1:10000 with distilled water and with an alkaline diluent to inhibit THP polymerization<br />

under acidic urine conditions.<br />

Results: The range of the ELISA calibration curve was 0–40 μg/L, and the lower detection limit was<br />

0.313 μg/L. The dilution curves of urine samples showed good linearity. The within-run CV and the<br />

between-day CV were less than 8%. The assay recovery was 81–123%. The urinary THP concentrations<br />

of the patients with glomerulonephritis (10.8 ± 2.04 mg/L) were significantly lower than those of the<br />

healthy subjects (49.2 ± 5.48 mg/L).<br />

Conclusion: The newly developed ELISA showed high sensitivity <strong>for</strong> detecting THP in highly diluted<br />

urine samples and showed that urinary THP levels could aid in diagnosing renal dysfunction.<br />

Sample pretreatment is often a time consuming and laborsome step which can be a restricting factor <strong>for</strong><br />

the rapid analysis. This is especially true <strong>for</strong> the analysis of drugs in biofluids containing many<br />

interfering matrices. There<strong>for</strong>e, we developed a direct analysis method <strong>for</strong> drugs in biofluids, using a<br />

polymer-based reversed-phase HPLC column which has a unique feature of retaining hydrophilic target<br />

compounds while excluding large biological matrices prior to the elution of targets. Following<br />

conditions were used. Column; Shodex ODP2 HP-4D (4.6 mm ID x 150 mm L) and ODP2 HP-4E (4.6<br />

mm ID x 250 mm L) from Showa Denko K.K. Eluent; 0.1% TFA/CH3CN = 93/7. Flow rate; between<br />

0.3 and 0.6 mL/min. Injection volume; from 5 to 10 uL. Detector; UV with wavelength between 215 and<br />

272 nm. Column temperature; 40°C. Standards were prepared in the eluent. Optimal conditions <strong>for</strong> each<br />

target and biofluids varied slightly. For the identification purpose, each peak were fractionated, and then<br />

injected directly to a MS/MS. The components of typical cold medicines were detected without the<br />

influence of biological matrices. Blood serum, urine, and gastric juice samples were collected from<br />

suspected drug-poisoned patients transported to the emergency and critical care medicine. Several<br />

components in cold medicine were detected in one patient’s serum: 44.1 ug/mL acetaminophen, 11.0<br />

ug/mL dihydrocodein phosphate, and 22.6 ug/mL aspirin. A small amount of salicylamide and salicylic<br />

acid was also found. Theophylline and risperidone were detectable in other patients’ serum samples. In<br />

one case of accidental insecticide poisoning, imidacloprid was detected in the patient’s gastric juice.<br />

The presented method using the ODP2 HP column provides a simple and rapid analysis of drugs in<br />

biofluids without the necessity of complex sample pretreatment. This method is applicable <strong>for</strong> the<br />

diagnosis and treatment of patients who are poisoned or overdosed counter medicine.<br />

Background: Chronic kidney disease (CKD) has been recognized as an independent risk factor <strong>for</strong><br />

coronary heart disease (CHD). Indoxyl sulfate (IS), one of uremic toxins, may play an important role<br />

in cardio-renal syndrome and our previous in vitro study showed that IS mediates vascular toxicity<br />

through enhanced oxidative stress in human endothelial cells. However, it is still unclear how<br />

accumulated IS in patients with renal dysfunction affects clinical outcome in those patients. In the<br />

present study, we examined the relation between CHD and serum IS levels in patients with CKD.<br />

Methods: In November 2010, patients in different CKD stages were divided into two groups (CHD<br />

group n=50 and non-CHD group n=62). CHD was diagnosed by coronary angiography, nuclear<br />

cardiac scintigraphy or multi-slice CT. The background and clinical characteristics of two groups were<br />

compared using receiver-operating characteristic analysis and multivariate analysis. The cut-off value of<br />

serum IS level was calculated to achieve its risk index on CHD.<br />

Results: Serum IS levels were significantly higher in the CHD group than in the non-CHD group<br />

Since folic acid deficiency in early pregnancy may cause neural tube closure defect in embryos,<br />

Japanese Ministry of Health, Labour and Welfare recommends a daily intake of 0.4 mg folic acid <strong>for</strong><br />

women who can become pregnant. It has been believed that the food folate is generally sufficient in<br />

Japanese adults, however, it has been suggested that recent changes in domestic eating habits might<br />

have reduced the intake. Thus, we measured folic acid in sera of Japanese healthy adults using a<br />

chemiluminescent enzyme immunoassay (CLEIA), and here report the reference value obtained as a<br />

result.<br />

Materials and Methods<br />

Three hundreds and fifty-nine healthy volunteers in our hospital were enrolled in the study. Serum<br />

folic acid, vitamin B12 and ferritin were measured on an Access2 analyzer (Beckman-Coulter Inc.).<br />

Results<br />

The reference value between the 2.5th and 97.5th percentiles in the frequency distribution of serum<br />

folate levels was determined as 2.41-11.93 ng/mL. Median values <strong>for</strong> serum folate levels were: 4.16<br />

ng/mL in males, 4.75 ng/mL in females, and 4.57 ng/mL in all subjects. Serum folate levels tended to be<br />

higher in females and lower in younger subjects.<br />

Discussion<br />

Our reference value <strong>for</strong> serum folate levels is similar to that reported previously in the UK using the<br />

same analyzer. The finding that serum folate levels are higher in female subjects is also consistent with<br />

the previous reports. The reason why serum folate levels were lower in our younger subjects is<br />

unknown, but might be explained by differences in eating habits between generations. We are preparing<br />

to report a further study on serum folate levels in pregnant women and anemic patients.<br />

Effects of alpha lipoic acid as an antioxidant in preventing renal mitochondrial<br />

oxidative damage in diabetic rats<br />

Noraihan Mat Harun, Rahajoe Imam Santosa<br />

Department of Basic Medical Sciences, Kulliyyah of Medicine, International Islamic University,<br />

Malaysia, Kuantan-Malaysia<br />

Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia due to inadequate<br />

secretion of insulin or insufficient action of the endogenous insulin. Oxidative stress has an important<br />

role in the pathogenesis of diabetic complications and mitochondria represent a major source of the<br />

reactive oxidants that lead to cellular oxidative damage. This study is design to observe the effect of<br />

alpha lipoic acid (ALA) as mitochondrial antioxidant in preventing renal mitochondrial oxidative<br />

damage in diabetic induced rats. In this study, the rats were divided into three groups. Normal Control<br />

(NC) group was served as a control; Diabetic Control (DC) group was induced <strong>for</strong> diabetes without<br />

given any supplementation, while Diabetic-Alpha Lipoic Acid (D-ALA) group was<br />

streptozotocin-induced diabetic rats, supplemented with ALA daily <strong>for</strong> six weeks. The ability of ALA in<br />

preventing renal mitochondrial oxidative damage was evaluated by comparing the renal function in<br />

terms of serum urea, serum creatinine and creatinine clearance in both supplemented and<br />

non-supplemented rats, as well as mitochondrial H2O2 concentration and GSH/GSSG ratio as parameters<br />

<strong>for</strong> the oxidative stress. The results showed that ALA capable to ameliorate the defective antioxidant<br />

defense system leads to modulate the oxidative stress in terms of lower H2O2 concentration and higher<br />

GSH/GSSG ratio in D-ALA group compared with DC group. However the significant reduction of<br />

oxidative stress did not correlate well with the renal function parameters, in which only showed<br />

significant improvement of serum urea, but not serum creatinine or creatinine clearance. In conclusion,<br />

ALA treatment capable to ameliorate the defective antioxidant defense system and modulate the<br />

oxidative stress, but partially preventing the progression of renal dysfunction in diabetic rats.<br />

Background: It has been well documented that con<strong>for</strong>mational changes via instability of tetrameric <strong>for</strong>m<br />

TTR occurs during the process of amyloid <strong>for</strong>mation in FAP. Some cryptic epitopes expose on<br />

amyloidogenic TTR (ATTR) molecule surface during the process in sera of FAP patients. There is a<br />

possibility that de novo antibodies responded to cryptic epitopes of ATTR may be synthesized in serum<br />

of FAP patients. Objective: To examine whether a relationship exists between the incidence of<br />

autoantibodies against ATTR and the phenotype of FAP ATTR V30M. Methods: Serum samples were<br />

collected from 25 Japanese (28-32 years old) and 8 Swedish (67-81 years old) FAP ATTR V30M<br />

patients, 4 Japanese gene carriers of ATTR V30M, and 24 Japanese healthy controls which had no<br />

genetic mutations of TTR. To detect the presence of autoantibodies against ATTR in these serum<br />

samples, enzyme-linked immunosorbent assay (ELISA) using recombinant ATTR V30M protein was<br />

immobilized on a polystyrene microtiter plates. Correlation between data of the ELISA and age of the<br />

subjects or duration of FAP was investigated. Results: Three of 25 Japanese and 5 of 8 Swedish FAP<br />

ATTR V30M patients were found to have autoantibodies against ATTR, and these 8 patients were all<br />

late onset cases. Moreover, significant positive correlation between the presence of the antibody and age<br />

was observed in all the patients examined (r=0.77, p < 0.05). We are now trying to detect<br />

con<strong>for</strong>mational epitope binding to the autoantibodies against ATTR V30M. Our preliminary data<br />

suggested the possibility that there were some epitopes at positions 24-35 or 105-115 of ATTRV30M.<br />

Conclusions: Age-dependent increase in the incidence of autoantibodies was observed in patients with<br />

FAP ATTR V30M. This phenomenon may influence the clinicopathological differences between both<br />

Aim Reference material is a key in setting reference measurement system. If it is serum-matrix base<br />

and analytes contained are closely similar, it can be used <strong>for</strong> many other clinically relevant purposes.<br />

We have newly developed the multi-purpose serum-matrix base reference material.<br />

Materials and Methods The material was prepared in a similar manner as ERM-DA470, an<br />

international reference material of serum proteins, IRMM. In short it is lyophilized after processing<br />

normal pooled sera (Shima Laboratories, Japan), reconstituted with hepes buffer, and spiked with CRP,<br />

cystatin C, and beta-2-microglobulin.<br />

Results We have successfully prepared the material with high safety, short-term stability, and<br />

long-term stability. Tests are negative <strong>for</strong> HBV, HCV, and HIV. After reconstituting with 1 ml of water<br />

the value was unchanged at 4ºC and room temperature until 12 hours. We confirmed the stability <strong>for</strong><br />

one year. Storage at 4ºC and -80ºC gave a good result. These include CRP, cystatin C, beta<br />

2-microoglobulin, pepsinogen I, II, and others. No inter-vial differences are noted. 31 different serum<br />

proteins and cytokine value was initially set by participation of immunoassay systems. The value in<br />

each analyte was generally 2/3 of that of normal adult, which may be caused by amount of distilled<br />

water added. Some minute discrepancy was found in the reaction of cystatin C and beta2-microglobulin<br />

between the material and patient’s sera.<br />

Comments The present prepared material definitely play a unique role <strong>for</strong> standardization <strong>for</strong><br />

immunoassay of different kinds of analytes, especially non-standardized controls <strong>for</strong> everyday’s<br />

laboratory services, and references of a given analyte <strong>for</strong> experimental purpose.<br />

Temporal changes in estimated glomerular filtration rate (delta eGFR) may be a<br />

predictor of progression to coronary heart disease<br />

Department of Laboratory Medicine, Asan Medical Center and University of Ulsan College of Medicine,<br />

Seoul, Korea<br />

Background: Chronic kidney disease and cardiovascular disease are major public health problems<br />

worldwide and often share the same pathophysiological mechanisms. Indeed, the prevalence of<br />

traditional cardiovascular risk factors can be higher in those with impaired kidney function, and most<br />

patients with a lower estimated glomerular filtration rate (eGFR) die of cardiovascular causes and not<br />

due to progression to end stage renal disease. However, the effect of reduced eGFR on coronary heart<br />

disease has not been well delineated among Korean population. Here, we reviewed temporal changes in<br />

eGFR (delta eGFR, ΔeGFR) of the healthy Korean population, and then, carried out a study to<br />

investigate the link between a ΔeGFR and the risk of coronary heart disease.<br />

Methods: We reviewed data of 7676 healthy outpatients selected from a population of - 10,000<br />

individuals referred to the health promotion center of the ASAN medical center between January 2010<br />

and December 2010. At the time of the first evaluation, data of patients` age, sex, blood pressure,<br />

creatinine, total cholesterol, LDL, HDL and triglycerides as well as history of smoking, hypertension or<br />

familial coronary heart disease were collected by chart review. The % risk of coronary heart disease<br />

were calculated by Framingham score (Score:www.nhlbi.nih.gov/guidelines/cholesterol). We classified<br />

ΔeGFR % into 4 groups according to Gaussian distribution, ±2 standard deviation (SD); below -2SD,<br />

-2SD to mean, mean to +2SD, over +2SD (mean=1.559, SD=9.5837).<br />

Results: Among the enrolled patients, 5.9% (456 patients) were over 15 of the Framingham score, and<br />

this is equivalent of coronary heart disease risk over 20% which means they have high risk <strong>for</strong><br />

occurrence of coronary heart disease in ten yrs. A group of over +2SD (ΔeGFR > 19.17%) had odds<br />

ratio of 3.656, and it was related to incident % risk of coronary heart disease rather than other ΔeGFR<br />

groups.<br />

Conclusions: A decline of eGFR > 19.17% was independently related to incident % risk of coronary<br />

heart disease. ΔeGFR could be a possible indicator of progression to the coronary heart disease in<br />

general population. There<strong>for</strong>e, this parameter may be potentially used <strong>for</strong> screening subjects with higher<br />

risk of coronary heart disease.<br />

Development of C-reactive protein assay <strong>for</strong> human saliva<br />

Yumi Narita, Taku Shirakawa<br />

Department of Biophysics, Graduate School of Health Sciences, Kobe University, Japan<br />

BACKGROUND: Measurement of C-reactive protein (CRP) in saliva may be able to be used <strong>for</strong> the<br />

early detection of the inflammatory disorder of infants or home care patients. However, the reports about<br />

the correlation between salivary and serum CRP vary among researchers. Such differences might be<br />

caused in the step of pretreatment or collection of saliva. In this study, we examined these steps in order<br />

to develop a high-sensitivity assay <strong>for</strong> salivary CRP.<br />

METHODS: Salivary CRP concentration was determined by sandwich enzyme-linked immunoassay<br />

(ELISA). To improve the sensitivity of the assay, Ampliflu TM Red (Sigma) was used as a fluorogenic<br />

substrate. Saliva was collected by drooling and/or saliva collection swab. Saliva samples were diluted<br />

1:1 in sample diluent containing Tween20 and/or cation, then centrifuge at 1500g <strong>for</strong> 5 minutes.<br />

Concentrations of Tween20 and cations were examined in 0 to 1% and 0 to 1000mM, respectively. The<br />

validity of ELISA was examined by intra-assay precision and recovery test. Saliva and serum samples<br />

from 28 healthy volunteers were collected, and then CRP concentrations were measured in order to<br />

evaluate the correlation of salivary and serum CRP.<br />

RESULTS: 500mmol/L MgCl2 and 0.25%Tween20 were best at enhancing the CRP fluorescent signal.<br />

Both MgCl2 and Tween20 were essential to detect strong signal. Under these conditions intra-assay CV<br />

was 3.0%, and recovery was 102-107%. CRP concentration decreased 30% in samples collected with<br />

saliva collection swabs in comparison with drooling. CRP was measurable in saliva samples (84.8 to<br />

4104.3pg/mL) and serum samples (26.0 to 2015.4ng/mL). There was a positive correlation between<br />

salivary and serum CRP (r=0.77).<br />

CONCLUSIONS: Strong enhancement of CRP fluorescent signal was observed in the presence of<br />

MgCl2 and Tween20. Salivary CRP concentration was affected by collection method. Salivary CRP and<br />

serum CRP moderately correlated. This result will support <strong>for</strong> the validation of salivary CRP as an<br />

alternative marker of inflammation.<br />

Introduction: Iodine deficiency is a leading cause of preventable mental retardation in the world today<br />

affecting 19.4% population of Nepal. It is particularly affect the developing brain of fetus and neonates.<br />

The geographical situation and poor accessibility of adequately iodized salt are the main cause of iodine<br />

deficiency in our country. Urinary iodine excretion (UIE) reflects current iodine intake and salt iodine<br />

content explore the level of iodine in household level.<br />

Objective: To assess the iodine status of the school children in Eastern Nepal.<br />

Materials and methods: A community based study was conducted on twelve districts of the Eastern<br />

Nepal representing hilly (Taplejung, Panchthar, Ilam, Dhankuta, Tehrathum and Sankhuwasabha) and<br />

plain region (Jhapa, Morang, Sunsari, Saptari, Siraha and Udayapur) on January 2008 to January 2012.<br />

A total of 4525 primary school children (6-12 years) were enrolled in the study and equal numbers of<br />

salt and urine samples were collected <strong>for</strong> the assessment of iodine status. UIE was measured by<br />

ammonium-persulphate digestion microplate (APDM) method and salt iodine content by semi<br />

quantitative rapid test kit.<br />

Results: Our study showed that 583 (12.9%) of school consumed open salt whereas 3942 (87.1%)<br />

consumed packet salt. Majority (86.7%) of school children consumed adequately iodized salt but 10.2%<br />

consumed inadequately iodized salt and 1.1 % children consumed salt with no iodine. The median UIE<br />

of the all school children is 241.08µg/L indicate the adequate iodine nutrition but still 13.1% children<br />

were suffering from some degree of iodine deficiency.<br />

Conclusion: Based on the result we conclude that iodine status of the school children in Eastern Nepal<br />

is improving but continuous monitoring of the population is necessary <strong>for</strong> the sustainable elimination of<br />

iodine deficiency disorders (IDD) from the country and prevention of iodine induced diseases.<br />

[Introduction] The clinical differential diagnosis of classic 21-hydroxylase deficiency (C21OHD) and<br />

cytochrome P450 oxidoreductase deficiency (PORD) is sometimes difficult since both deficiencies can<br />

have similar phenotypes and high blood concentrations of 17α-hydroxyprogesterone (17OHP). The<br />

objective of this study was to explore novel biochemical indexes <strong>for</strong> the differential diagnosis of<br />

C21OHD, PORD, and transient hyper 17α-hydroxyprogesteronemia (TH17OHP) in Japanese newborns.<br />

[Material and Methods] We recruited 29 infants with C21OHD, 9 infants with PORD, 67 infants with<br />

TH17OHP, and 1341 control infants. All infants were Japanese between 0-180 days old. None<br />

received glucocorticoid treatment be<strong>for</strong>e urine sampling. We measured urinary pregnanetriolone (Ptl),<br />

the cortisol metabolites 5α- and 5β-tetrahydrocortisone (sum of these metabolites defined THEs), and<br />

metabolites of three steroids, namely dehydroepiandrosterone, androstenedione (AD4) and<br />

11β-hydroxyandrostenedione (11OHAD4) by gas chromatography-mass spectrometry.<br />

[Results] By using a cutoff 0.020, the ratio of Ptl to THEs, we were able to differentiate C21OHD and<br />

PORD from TH17OHP and controls with no overlap (minimum – maximum: 0.14-15, 0.051-0.23,<br />

0.00010-0.011, and 0.000068-0.0083, respectively). Among metabolites of DHEA, AD4, and<br />

11OHAD4, only 11β-hydroxyandrosterone (11HA), a metabolite of 11OHAD4, showed no overlap<br />

between C21OHD and PORD (0.61-24 and 0.022-0.22 mg/g creatinine, respectively) using a cutoff of<br />

0.35.<br />

[Conclusion] We successfully established a 2-step biochemical differential diagnosis <strong>for</strong> C21OHD and<br />

PORD by urinary steroid metabolites such as Ptl, THEs, and 11HA.<br />

Prediabetic patients can progress to type 2 diabetes mellitus (t2DM) and cardiovascular disease<br />

(CVD). Lipid profile has an important role in CVD. However there is still few data about Apo B level,<br />

total cholesterol/HDL-cholesterol ratio (TC/HDL-C ratio) and LDL-cholesterol /Apo B ratio<br />

(LDL-C/ApoB ratio) in first-degree relatives from patients with t2DM in Indonesia. This study aimed<br />

to get picture of Apo B level, TC/HDL-C and LDL-C/Apo B ratios in the first degree relatives from<br />

patients with t2DM as markers <strong>for</strong> early detection of CVD.<br />

The prediabetes i.e. impaired fasting glucose or impaired glucose tolerance was diagnosed based on<br />

blood glucose level. This cross sectional designed study consisted of 56 prediabetic subjects and 56<br />

normoglycaemic subjects, all were the first-degree relatives from patients with t2DM. Total cholesterol,<br />

HDL cholesterol, LDL cholesterol were determined by enzymatic and direct homogenous enzymatic<br />

methods whereas Apo B was determined by immunoturbidimetric methods.<br />

In prediabetic subgroup TC/HDL-C ratio was significantly higher (4.5±1.1 vs 3.2± 0.5; p

Adiponectin HMW Level and Homeostasis Model Assessment-Insulin Resistance<br />

(HOMA-IR) in Type 2 Diabetes Mellitus First Degree Relatives<br />

Yulia Sari, Marzuki Suryaatmadja, Budiman Darmowidjojo<br />

Department of Clinical Pathology, Medical Faculty, Universitas Indonesia<br />

Type 2 diabetes mellitus (t2DM) accompanied by macro and microangiopathy complications had<br />

been a serious global problem, with an increasing morbidity and mortality rates.<br />

The most important pathogenesis is insulin resistance (IR), which could be predicted by the<br />

Homeostasis Model Assessment-Insulin Resistance (HOMA-IR). Adiponectin has been<br />

already known to increase the insulin sensitivity and play role in balancing the<br />

glucose metabolism. It is very important to be able to detect the prediabetes early to prevent the<br />

complications.. The aim of this study is to get the picture of adiponectin HMW level and the HOMA-IR<br />

as IR predictors in the t2DM first degree relatives, and the correlation between adiponectin level with<br />

fasting insulin and HOMA-IR. This cross-sectional designed study was conducted from April 2011 until<br />

January 2012, on t2DM first degree relatives. The subjects consisted of 52 prediabetes and 52<br />

normoglycaemic respondents. The result revealed that in prediabetic group, the adiponectin HMW<br />

levels in both men and women were significantly lower (P=0,003), HOMA-IR were significantly higher<br />

than in the normoglycaemic group (P=0,0026), and there were negative correlations<br />

between adiponectin HMW level in both men and women with HOMA-IR and fasting<br />

insulin. These findings had proven that IR had been presented in prediabetes stage which was correlate<br />

well to the hypoadiponectinemia. Based on these results, it is recommended to measure adiponectin<br />

HMW, insulin and HOMA-IR in t2DM first degree relatives to detect the IR and to prevent the sickness<br />

earlier to decrease the morbidity and mortality rates.<br />

Seoul Medical Science Institute/Seoul Clinical Laboratories, Seoul, Korea 1 , Department of Obstetrics<br />

and Gynecology, School of Medicine, Keimyung University, Daegu, Korea 2<br />

Backgrounds : Currently, serum anti-Müllerian hormone (AMH) in women has been increasingly used<br />

<strong>for</strong> ovarian reserve function assessment in fertility centers. Here we evaluated age-related AMH values<br />

in various ages of healthy females in Korea, and investigated the relationships with antral follicle count<br />

(AFC) and other fertility hormones.<br />

Methods: We recruited 222 healthy females without specific infertility history in various ages. For<br />

women of reproductive age, blood samples were drawn at day 3 from the onset of cycle. AMH was<br />

measured by ELISA (Immunotech SAS, France). E2, FSH and LH were measured by<br />

chemiluminescence immunoassay (ADVIA Centaur ® XP, Siemens, USA). Statistical analysis was<br />

per<strong>for</strong>med using MedCalc software (version 12.3, Belgium). AMH values were calculated in different<br />

age groups, and correlation of AMH and other hormones were analyzed. For 104 patients whose AFC<br />

assessment was available, correlations of AFC and each hormone were also analyzed.<br />

Results: 2.5 - 97.5 percentiles of AMH values depending age groups are as follows: 0.10 - 3.99 ng/mL<br />

(60 years, n=43). AMH negatively correlated with FSH (r =<br />

-0.4213, P < 0.0001), LH (r = -0.3858, P < 0.0001) and E2 (r = -0.2070, P = 0.0025). Regarding the<br />

relationship of each hormone with AFC, AMH positively correlated with AFC (r = 0.7375, P < 0.0001),<br />

while negatively correlated FSH (r = -0.5401, P < 0.0001).<br />

Conclusion: AMH values should be interpreted in caution, with regard to women’s age, because AMH<br />

values are steadily increased from birth until 20 th , and continuously decreased after 30 th . AMH best<br />

correlates with AFC, which suggest AMH is one of the most promising markers <strong>for</strong> assessment of<br />

ovarian reserve function.<br />

The aim of this study was to analyze von Willebrand Factor (vWF) level as the risk factor of thrombosis<br />

in type 2 diabetes mellitus. A cross sectional study had been done at Endocrine Metabolic Subdivision<br />

Department of Internal Medicine of Wahidin Sudirohusodo Hospital. Laboratory examination had been<br />

done at Clinical Pathology Laboratory of Wahidin Sudirohusodo Hospital Makassar. Seventy-five<br />

participants consisted of 52 subjects with type 2 DM and 25 normal subjects as controls had been<br />

examined. The results of this study showed that the age of type 2 DM subjects were ranging from 39-74<br />

years old and the age of normal controls were ranging from 30-44 years old. The level of vWF in type 2<br />

DM and normal controls were 86-362% and 41-210%, respectively. There was significantly increased of<br />

vWF level in type 2 DM. It was proven that in subject with type 2 DM occurred hypercoagulation states<br />

that characterized by elevated level of vWF. The level of vWF is suggested to be a marker of<br />

hypercoagulation states caused by endothelial dysfunction in type 2 DM. Further study is suggested to<br />

determine the level of vWF in type 2 DM by including other risk factors such as hypertension,<br />

dyslipidemia, smoking and obesity.<br />

Combination of Anti-HCV Assay to Improve Per<strong>for</strong>mance of Hepatitis C Screening<br />

Test in Prodia National Reference Laboratory, Indonesia<br />

Romimatul Fadhilah, Yenny Surjawan, Indriyanti R. Sukmawati<br />

Prodia Clinical Laboratory, Indonesia<br />

Anti-HCV assay <strong>for</strong> hepatitis C screening test has been widely used. Based on CDC guideline (2003),<br />

positive anti-HCV screening result has to be verified by immunoblotting assay or nucleic acid testing. In<br />

fact, not all laboratories in Indonesia have facilities to per<strong>for</strong>m this test. Prodia National Reference<br />

Laboratory received samples <strong>for</strong> anti-HCV screening test from its hundred branches. Samples sources<br />

were from vary population with varying prevalence of hepatitis C. In our experience, samples referred<br />

<strong>for</strong> anti-HCV assay from other laboratories quite often showed discordance results with ours. Previous<br />

evaluation of 4 automated analyzers <strong>for</strong> anti-HCV assay by Kim et al (2008) showed good sensitivity<br />

(100 %), but 3.7 % still showed false positive results. There<strong>for</strong>e an evaluation of routine anti-HCV<br />

screening test should be per<strong>for</strong>med. We evaluated 55 samples using 3 analyzers (Advia Centaur,<br />

Architect-i2000 and Axsym). Seventeen samples that showed discordant results among analyzers or had<br />

extreme low and high index or s/co were confirmed by immunoblotting assay using INNO-LIA TM HCV<br />

Score reagent (Innogenetics). The sensitivity of anti-HCV assay on those 3 analyzers was good (100 %).<br />

False positive results were found in 4 samples by Architect, 5 samples by Advia and 5 samples by<br />

Axsym. The assay showed a different result if a sample, especially sample with low s/co ratio or index,<br />

was examined with different analyzers. The false positive results were not found in the same samples<br />

and there were no specific pattern. There<strong>for</strong>e, we consider using a second anti-HCV assay as<br />

recommended by UK Health Protection Agency algorithm (2007) <strong>for</strong> results with low s/co ratio or index<br />

to reduce the possibility of false positive result.<br />

AIM: Although, alpha-fetoprotein (AFP) is the most widely used tumor marker <strong>for</strong> hepatocellular<br />

carcinoma (HCC), AFP lacks adequate sensitivity and specificity <strong>for</strong> effective surveillance. The aim of<br />

this study was to evaluate diagnostic value of AFP-L3 and Prothrombin induced by vitamin K<br />

absence-II (PIVKA-II) in HCC.<br />

METHODS: One hundred and sixty-eight patients (90 HCC, 78 benign liver diseases) during routine<br />

HCC surveillance were included. Sera were obtained during their first evaluation <strong>for</strong> HCC development<br />

and at the time of HCC diagnosis be<strong>for</strong>e commencing HCC treatment. AFP, AFP-L3 and PIVKA-II<br />

were measured in the same serum by microchip capillary electrophoresis and liquid-phase binding assay<br />

on a μTAS Wako i30 auto analyzer<br />

RESULTS: In a total of 168 patients, areas under the curve (AUC) <strong>for</strong> HCC were 0.879, 0.887, 0.801<br />

and 0.939 <strong>for</strong> AFP, AFP-L3, PIVKA-II and the combined markers, respectively. AFP-L3 had higher<br />

AUC than PIVKA-II <strong>for</strong> HCC (P = 0.043). In 112 patients with low AFP levels (5%) and PIVKA-II (cut-off >40AU/L), the sensitivities were 92.1-94.4% and<br />

specificities were 75.6-79.7% in all patients and subgroup. Combined markers detected about 90% of<br />

early stage, small sized or single tumors in the low AFP group. In multivariate analysis, AFP-L3 was<br />

correlated with AFP and tumor size, and PIVKA-II was correlated with laboratory tests including serum<br />

AST, total bilirubin, platelets and albumin levels. PIVKA-II had no correlation with AFP, AFP-L3 or<br />

tumor characteristics.<br />

CONCLUSION: Combined determination of AFP-L3 and PIVKA-II could improve the diagnostic<br />

value <strong>for</strong> HCC detection in patients with or without increased AFP levels. The utility of improved<br />

surveillance protocol based on these tumor markers needs to be investigated.<br />

Development of ABO and Lewis typing by enzyme-linked immunosorbent assay <strong>for</strong><br />

disaster<br />

Terutaka Sagawa and Mariko Okada<br />

Division of Biomedical Sciences, Institute of Medical Technology, Ehime Prefectural University Of<br />

Health Sciences, Japan<br />

For ABO blood group typing, we need electrical power, the clean area <strong>for</strong> collecting venous blood and<br />

substantial experience of technologists. We have little electrical power, clean areas and human resources<br />

after a disaster, just like a giant earthquake or a giant tsunami, occurs. In this case, there is a need of the<br />

method that does not require electrical power, the clean area and substantial experience.<br />

We have developed ABO and Lewis blood group typing by enzyme-linked immunosorbent assay<br />

( ELISA ) using Japanese saliva as antigen. Tween 20 was used to block and wash. This method could<br />

give a result within 120 minutes from saliva collecting procedure.<br />

All secretors (88% of the samples examined) reacted with anti-H Ab.<br />

Nonsecretors reacted weakly with anti-H Ab or not. A-type and AB-type nonsecretors reacted weakly<br />

with anti-A Ab. B-type and AB-type nonsecretors reacted weakly with anti-B polyclonal antibody but<br />

not anti-B monoclonal antibody.<br />

Secretors included Lea-Leb- (19% of secretors), Lea-Leb+ (28%) and Lea+Leb+ (53%). All<br />

nonsecretors reacted with anti-Lea Ab not anti-Leb Ab.<br />

Kudo et al. demonstrated that almost Japanese nonsecretors had sej/sej homozygosity. The sej/sej has<br />

an elevated ABH antigen. No activity alleles are very rare in Japanese.<br />

It was proved that the ELISA method reported here was useful <strong>for</strong> almost Japanese ABO and Lewis<br />

blood group typing, and did not require electrical power and substantial experience. Further<br />

developments are necessary <strong>for</strong> very rare Japanese complete nosecretors, and Rh typing and ABO<br />

reverse typing.<br />

Introduction: In hemodialysis patients, early detection of hepatitis A, B and C is very important. While<br />

serology test <strong>for</strong> detection of hepatitis A, B and C is used, it has limitation in that it does not catch the<br />

early infection and co-infection of hepatitis A, B and C. Recently a multiplex PCR kit <strong>for</strong> the<br />

simultaneous detection of hepatitis A, B and C, Hepatrio, was developed. We evaluated the multiplex kit<br />

in hemodialysis patients in one Korea hospital and compared the result with serology.<br />

Methods: HAV IgM, HBsAg, anti-HBs, anti-HBc and HCV Ab were analyzed on 186 samples of<br />

routine check-up examinees in a hemodialysis care unit by chemiluminescence immunoassay. Nucleic<br />

acid amplification test (NAT) was per<strong>for</strong>med on the same samples by multiplex real-time polymerase<br />

chain reaction (PCR) kit <strong>for</strong> simultaneous detection of HAV, HBV, and HCV (Magicplex Hepatrio;<br />

Seegene, Seoul, South Korea).<br />

Results: The positive rates of HAV, HBV, and HCV were 0, 5.9, and 0.6%, respectively. All samples<br />

except two showed consistent results between serology and multiplex PCR. Occult HCV infection was<br />

found in 1 (0.6%) of 173 HCV-Ab negative subjects. Meanwhile, a HBs-Ag positive sample was not<br />

detected <strong>for</strong> HBV-DNA by multiplex PCR. There was no co-infection case among samples.<br />

Conclusion: This study suggests the possibility that multiplex PCR replaces serology <strong>for</strong> screening of<br />

hepatitis A, B and C. Further study using much more samples is needed <strong>for</strong> the clinical per<strong>for</strong>mance<br />

evaluation of multiplex PCR test. Key word: Hepatitis A, hepatitis B, hepatitis C, hemodialysis,<br />

Impact of interleukin-29 on interferon alpha secretion of plasmacytoid dendritic cell<br />

Chi Hyun Cho, M.D. 1 , Chae Seung Lim, M.D. and Yun Jung Cho, M.D. 1*<br />

1 Department of Laboratory Medicine, College of Medicine, Korea University, Seoul, Korea<br />

Background: The alpha-IFN secretion by plasmacytoid dendritic cell was distinguished by rapid<br />

kinetics, high level (up to 1000 fold higher than most cells), while the plasmacytoid dendritic cells<br />

responded with vigorous alpha-IFN production to stimulation by a variety of viral stimuli and to<br />

synthetic Toll-like receptor agonists. IL-28Rα (type III IFN receptor chain) signaling was demonstrated<br />

not to provide feedback on type I expression in mouse study. In this study, we tried to identify whether<br />

the type III IFN provides feedback or does not do so on alpha-IFN secretion of human plasmacytoid<br />

dendritic cell.<br />

Methods: From eleven healthy donors, 3 ml and 10 ml of whole blood were collected <strong>for</strong> complete<br />

blood cell count by Coulter automatic analyzer and <strong>for</strong> the isolation of peripheral blood mononuclear<br />

cells (PBMC). Plasmacytoid dendritic cell was counted by multiplying % of total PBMC<br />

(flowcytometer) by mononuclear cells of whole blood (Coulter automatic analyzer). PBMC from each<br />

healthy donor was then divided into four groups as follows: group 1- control; group 2- addition of CpG<br />

DNA; group 3- addition of IL-29; group 4- addition of CpG DNA and IL29. Then, the culture media<br />

were incubated <strong>for</strong> 24 hours at 37℃. The supernatants were collected and tested <strong>for</strong> the amount of<br />

IFN-alpha secretion by the flowcytometer.<br />

Results: The number of plasmacytoid dendritic cells (/µL) was 5.29 (±3.05). IFN-alpha (pg/ml)/pDC<br />

(/µL) in each group was as follows: 5.677 (±9.278) in group 1; 1071.546 (±1026.598) in group 2;<br />

14.142 (±21.107) in group 3; 1913.897 (±1525.928) in group 4. There were statistically significant<br />

differences between group 1 vs 2 and group 2 vs 4, whereas there was no statistically significant<br />

difference between group 1 vs 3. The addition of CpG DNA with IL-29 caused human pDC to secret<br />

IFN-alpha about two times more than addition of CpG DNA alone.<br />

Conclusions: Apart from mouse study, one of lambda-IFNs, IL-29 provided feedback on IFN-alpha<br />

expression of human pDC. IL-29 alone did not have impact on IFN-alpha secretion by human pDC, but<br />

with CpG DNA, had synergistic effect on that. Given the knowledge that IL-29 is potential therapeutic<br />

alternatives to type I IFNs in terms of viral infections and tumors, this result could help elucidate the<br />

mechanism of the therapeutic effect by IL-29.<br />

Key Words : CpG DNA, IL-29, IFN-alpha, plasmacytoid dendritic cell<br />

containing anti-‘Mi a ’ specificity were collected routinely in our blood bank. Manual polybrene method<br />

without a supplementary antiglobulin phase was used <strong>for</strong> serologic test. The results of serologic test<br />

were compared with PCR-sequencing data. The study was approved by our Institutional Review Board.<br />

Results. The prevalence of Mi.Ⅲ(GP.Mur) is 6.4% (25/389). Among 1945 serologic tests <strong>for</strong> these<br />

389 samples, 210 tests showed a positive reaction (1+ or more). Among them, only 84 positive results<br />

belonged to PCR (+) samples. The sensitivity and specificity of our routine practice using ‘Mi a ’(+)<br />

screening cells to detect anti-‘Mi a ’ antibodies are thus estimated to 67.2% (84/125) and 93.1%<br />

(1694/1820), respectively. The positive predictive value is 40% (84/210).<br />

Conclusions. Our results showed that the Mi.III (GP.Mur) has a prevalence of 6.4% in Taiwan, and no<br />

GP.Hut, GP.Hop, GP.Bun, or GP.HF was detected. However, our study also showed that our screening<br />

system <strong>for</strong> detecting anti-‘Mi a ’ has a low sensitivity of 67.2% with a specificity of 93.1%. Since a<br />

previous study suggested the presence of other glycophorin variants in Taiwan, the results suggested the<br />

existence of other (Mi) phenotypes and the current detecting method may not be sufficient to identify<br />

antibodies other than anti-GP. Mur.<br />

Background: A malaria parasite antigen, merozoite surface protein 2 (MSP-2), is assumed to be<br />

involved in initial attachment of merozoite to erythrocyte surface. MSP-2 may contribute to the<br />

development of clinically protective immunity to malaria which is dependent upon cumulative exposure<br />

to the many parasite variants circulating in the local population. The aim of this study is to determine<br />

immune response to MSP-2 P.falciparum in individuals living in Mamuju, an epidemic area of malaria<br />

in West Sulawesi, Indonesia. Methods: The cross sectional study was conducted using multi-stages<br />

random sampling from 15 districts (123 villages) in Mamuju, West Sulawesi, Indonesia. Capillary blood<br />

samples from 4406 participants were collected during August 2010. All positive samples and 5%<br />

negative samples based on blood smear results were selected randomly <strong>for</strong> immunological investigation.<br />

IgG antibodies to MSP-2 were analyzed by Enzyme Linked ImmunoSorbent Assay (ELISA) Results:<br />

Of 209 samples based on blood smear results, there were 18 samples with P.falciparum parasitaemia, 10<br />

samples with P.vivax parasitaemia and 181 negatives samples, Means of IgG antibody to MSP2 in<br />

individuals who had positive P.falciparum blood smears was 37.54 units, higher than positive P.vivax<br />

(7.48 units) and negative blood smears (2.61 units), there was a significant difference between the three<br />

groups (95%CI: p=0.0001). Cut off point of IgG antibody to MSP2 was 4.57 units. Of 37 samples with<br />

levels of IgG antibody to MSP2 more than cut off, 11 were from individuals with P.falciparum<br />

parasitaemia, 3 from individuals with P.vivax, and 23 from uninfected people. Conclusion: Increased<br />

level of IgG antibody to MSP2 was associated with infection with P.falciparum. The presence of IgG<br />

antibody to MSP2 in individuals with P.vivax infection or negative blood smears may indicate<br />

mix-infection of P.falciparum undetected by blood smear or previous infection with P.falciparum.<br />

Inhibition of the NF-kappa B pathway as a candidate strategy <strong>for</strong> treatment of<br />

cryopyrin-associated periodic syndrome<br />

Cryopyrin-associated periodic syndrome (CAPS) is caused by a mutation in the CIAS1 gene coding <strong>for</strong><br />

NLRP3. Once activated by pathogen-associated molecular patterns (PAMPs) and/or damage-associated<br />

molecular patterns (DAMPs), NLRP3 <strong>for</strong>ms a protein complex referred to as an inflammasome, leading<br />

to extracellular release of IL-1beta. Since mutated NLRP3 <strong>for</strong>ms an inflammasome without obvious<br />

stimulation leading to the unrestricted release of IL-1beta, this cytokine represents a critical target <strong>for</strong><br />

CAPS treatment. This study aimed to test the effect of an NF-kappa B inhibitor DHMEQ (provided by<br />

Dr Umezawa, Aichi Medical University) upon IL-1beta production, as well as the expression of other<br />

proinflammatory molecules induced by IL-1beta.<br />

Human umbilical vein endothelial cells (HUVECs) and peripheral blood mononuclear cells (PBMCs)<br />

were stimulated and mRNA expression of proinflammatory proteins was assessed by quantitative<br />

RT-PCR. The effects of DHMEQ were tested in parallel with anakinra, an IL-1 receptor antagonist.<br />

Under stimulation by IL-1beta, mRNA expression <strong>for</strong> IL-1beta, TNF alpha, IL-6 and VCAM-1 in<br />

HUVECs was markedly increased, and this effect was almost completely suppressed by both DHMEQ<br />

and anakinra. However, when PBMCs were stimulated with IL-1beta, anakinra was less effective,<br />

possibly because cells were additionally stimulated by the secondary action of cytokines other than<br />

IL-1beta. Enhanced expression of IL-1beta mRNA in PBMCs stimulated with LPS alone, or LPS plus<br />

ATP, was effectively suppressed by DHMEQ but not by anakinra.<br />

In an assay system that mimics PAMPs and/or DAMPs induced IL-1beta production, DHMEQ<br />

effectively suppressed IL-1beta mRNA as well as other IL-1beta-induced mRNA of proinflammatory<br />

proteins, suggesting that DHMEQ is a good candidate agent <strong>for</strong> the treatment of CAPS.<br />

Gene Diagnoses of Tumors of Hematopoietic Organs - Diagnosis of Leukemia by<br />

both Southern Method and PCR Method –<br />

Kazuhiro Kabe<br />

Business Department of Medical Technology, Laboratory of Medical Technology<br />

Medic21 Association, Japan<br />

Aim : I introduced a genetic test <strong>for</strong> a diagnosis of lymphocytic leukemia that was one of tumors of<br />

hematopoietic organs. I detected the reconstituted genes of both Immunoglobulin-Heavy-Chain (IgH)<br />

and T-Cell-Receptor (TCR) with both Southern Method and PCR Method. And I made a trial of the<br />

diagnostic test of lymphomas of both B cell tumors and T cell tumors.<br />

Materials and Methods : There are V (V), D (D) and J (J) regions in IgH genes. I used Southern<br />

Method by probes to J and Semi-Nested PCR Method by primers to both V and J so as to detect the<br />

special unit (CDRⅢ) after IgH reconstitution. There are V (Vδ), D (Dδ) and J (Jδ) regions in TCR<br />

genes. I used Nested PCR Method by primers to Vδ, to Jδ and to the outside of both Vδ and Jδ so as to<br />

detect the special unit (Vδ1・D・Jδ1) after TCR reconstitution.<br />

Results : I could confirm the IgH reconstitution by Southern Method at the obvious cellular specimen<br />

of B cell leukemia and the TCR reconstitution by PCR Method at the obvious cellular specimen of T<br />

cell leukemia. As <strong>for</strong> the PCR limit, I could detect till the specimen that was 1/1000 as dilute as DNA<br />

(1µg) at IgH reconstitution and till the specimen that was 1/10000 as dilute as DNA (1µg) at TCR<br />

reconstitution.<br />

Conclusions : Southern Method is not sensitive enough and needs much DNA (10µg) and takes too<br />

much time <strong>for</strong> its work. PCR Method is highly sensitive and sufficient in small DNA (1µg) and this<br />

work is practicable in one day. As PCR Method is effective to operate and we seem to be able to expect<br />

the genetic test detect from peripheral blood.<br />

Acquired aplastic anaemia (AA) is recognized as an autoimmune disorder; however, the autoantigens<br />

and target cells involved remain elusive.<br />

Sera were obtained from acquired AA patients and the expression of autoantibodies and their target cells<br />

were examined using the haematopoietic cell line K562 and bone marrow stromal cell line hTS-5 by<br />

flow cytometric analysis; 43.5% and 21.7% of AA expressed autoantibody against K562 and hTS-5<br />

cells, respectively. A cDNA library was constructed using K562 mRNA and 8 autoantigens were<br />

identified by serological identification of antigens through recombinant cDNA expression cloning<br />

(SEREX). Expression level of anti-CLIC1, HSPB11 and RPS27 IgG-type autoantibodies were higher in<br />

patients with acquired AA than in normal volunteers. Moreover, 12 of 13 responders to<br />

immunosuppressive therapy expressed at least one IgG-type autoantibody against CLIC1, HSPB11 or<br />

RPS27, whereas all non-responders did not express any IgG-type autoantibody. Furthermore, higher<br />

titres of anti-CLIC1 and RPS27 IgG-type autoantibodies were found to be associated with better<br />

response rates to immunosuppressive therapy. The results of this study indicate haematopoietic cells are<br />

the targets of immune abnormality in acquired AA. These autoantibodies may be utilized to abstract<br />

patients associated with immune abnormality from bone marrow failure syndrome.<br />

Daisuke Kobayashi, Takashi Kondoh, Maki Tanaka, Kageaki Kuribayashi Naoki Watanabe<br />

Department of Clinical Laboratory Medicine, Sapporo Medical University, School of Medicine, Japan<br />

Objectives: Inhibitors against several tyrosine-kinases have been used in leukemia. However,<br />

therapeutic effect is somewhat limited by drug-resistance, and there<strong>for</strong>e it is urgent to seek <strong>for</strong> novel<br />

therapeutic targets. In this study, we analyzed the expression profile and clinical significance of<br />

STYK1, a unique tyrosine kinase promoting cell proliferation without ligand binding, in various<br />

leukemic patients.<br />

Patients and Methods: In peripheral blood cells from nonleukemic group (n=15), acute leukemia (AL)<br />

patients (n=26), and chronic myelogenous leukemia (CML) patients (n=19), STYK1 mRNA expression<br />

was analyzed by quantitative RT-PCR. Several small inhibitory RNA (siRNA) against STYK1 and<br />

non-silencing control RNA (NSC) were transduced by electroporation method using Nucleofector V<br />

and Nucleofector II (Amaxa).<br />

Results: 1) Mean measured value of STYK1 mRNA in AL and CML patients was 1,654±1,603 and<br />

477±388, respectively, resulting 7.9-fold and 2.3-fold increase compared to the expression in<br />

nonleukemic group (210±110). When appropriate cutoff was set using the values in nonleukemic<br />

individuals, positive STYK1 mRNA expression was detected in 76.9% and 42.1% of AL and CML<br />

patients, respectively. 2) STYK1 mRNA expression began to decrease after chemotherapy in AL<br />

patients, and in the patients showing resistance to therapy, STYK1 mRNA expression preceding therapy<br />

was significantly higher than in the patients with complete remission. 3) In the CML patients, no<br />

relationship was found between mRNA expression level and the copy numbers of bcr-abl gene<br />

(r=-0.21). 4) Transduction of siRNA into K562 cells with high STYK1 expression increased<br />

doxorubicin sensitivity compared to the cells transduced with NSC.<br />

Conclusion: These results indicate that STYK1 mRNA is highly expressed in the patients with<br />

several leukemic patients and suggest an important role of STYK1 in the drug- resistance of acute<br />

leukemic cells.<br />

Contribution of uncontrolled fibrinolysis to bleeding diathesis in aortic aneurysm<br />

Mitsuhiro Uchiba, Yuji Yonemura, Yukio Ando.<br />

Department of Blood Transfusion and Cell Therapy, Kumamoto University Hospital<br />

Kumamoto, Japan.<br />

[Background] Disseminated intravascular coagulation (DIC) is one of the severe complications<br />

observed in patients with aneurysm (AA). DIC results consumption coagulopathy following bleeding<br />

diathesis. Some investigators believe that hypofibrinogenemia resulted from consumption coagulopathy<br />

is a main cause of abnormal bleeding in AA. Bleeding diathesis is also caused by fibrinolytic<br />

abnormality, which is often complicated with AA. To determine whether hypofibrinogenemia and<br />

fibrinolytic abnormality contribute to bleeding diathesis observed in AA, we analyzed relationship<br />

between bleeding symptoms and plasma levels of fibrinogen and a2-antiplasmin (a2-AP), an important<br />

regulator of fibrinolysis. [Method] Plasma levels of fibrinogen and a2-AP in AA patients with and<br />

without bleeding were retrospectively analyzed. [Result] Levels of both fibrinogen and a2-AP were<br />

lower in AA patients with bleeding than in those without bleeding. Levels of a2-AP in AA patients with<br />

bleeding were lower than reference range, whereas that of fibrinogen in bleeding patients were within<br />

reference range. [Discussion] Our results indicated that a2-AP deficiency rather than<br />

hypofibrinogenemia contributed to bleeding in AA. Precise mechanisms were not fully elucidated,<br />

a2-AP deficiency resulting uncontrolled fibrinolysis may play a role. Although some investigators<br />

recommend normalizing fibrinogen levels by using fibrinogen concentrate instead of fresh frozen<br />

plasma in AA, our result indicated that maintaining the a2-AP level, but not fibrinogen levels, is<br />

important. There<strong>for</strong>e FFP but not fibrinogen concentrate should use to controlling abnormal bleeding<br />

observed in patients with AA.<br />

Development of resistance to Imatinib mesylate (IM) among a significant number of chronic myeloid<br />

leukemia (CML) patients has emerged as a major clinical problem. But, mutation analysis of our CML<br />

patients showed that BCR ABL mutations accounted <strong>for</strong> IM resistance in only 21.7% of CML patients,<br />

indicating involvement of other BCR-ABL independent genetic and epigenetic mechanisms in<br />

mediating resistance. We hypothesized that promoter hypermethylation of HOXA4, a gene involved in<br />

CML progression to blast crisis, could be an epigenetic mechanism mediating IM resistance in CML<br />

patients. Our objective was to determine the promoter hypermethylation status of HOXA4 in CML<br />

patients on IM treatment and to evaluate its role in mediating resistance. Genomic DNA was extracted<br />

from peripheral blood samples of 95 CML patients on IM therapy (38 good responders and 57 resistant)<br />

and 12 normal controls, followed by bisulfite treatment. Subsequently, Methylation Specific High<br />

Resolution Melt Analysis (MS-HRM) was per<strong>for</strong>med to quantitate the methylation level of 9 CpG site,<br />

located at -510 to -396 from the stop codon of HOXA4 gene. Five samples, representing each group of<br />

methylation level were selected <strong>for</strong> validation using pyrosequencing. Pyrosequencing results confirmed<br />

the methylation homogeneity of all the 9 CpG (mean SD is 4.7) in the HOXA4 promoter and their mean<br />

methylation percentage was concordant to the MS-HRM results. Compared to good responders, HOXA4<br />

hypermethylation level was significantly higher (P=0.002) in IM resistant CML patients. On evaluating<br />

the risk, HOXA4 hypermethylation was associated with higher risk <strong>for</strong> IM resistance (OR 4.658; 95% CI,<br />

1.673-12.971; P=0.003). These results prompt us to suggest that promoter hypermethylation of HOXA4<br />

gene could be an epigenetic mechanism mediating IM resistance in CML patients and could be<br />

considered as a potential epigenetic biomarker in addition to the BCR-ABL gene mutation, <strong>for</strong><br />

prediction of CML patients’ response to IM treatment.<br />

<br />

Red Blood Cells (RBCs) express Duffy antigen receptor <strong>for</strong> chemokines (DARC) on the surface. DARC<br />

is a decoy receptor with no signal transduction into RBC and binds to several Chemokines such as IL-8,<br />

MCP-1, Eotaxin and RANTES. Biological function of DARC is thought to be a scavenger of<br />

chemokines promoting chemokine concentration gradient to facilitate inflammatory cell migration in<br />

the focus of inflammation. The aim of this study is to investigate how these chemokines scavenged by<br />

RBC.<br />

<br />

Blood (3.0 ml) was drawn from healthy volunteers aged 20 to 30 years and collected into EDTA tubes<br />

containing K2EDTA (1.5 mg/ml). After centrifugation (430 G, 10 min), 200 µl of RBC was taken from<br />

the bottom of the tube and washed three times with PBS. The expression of DARC and RANTES was<br />

measured by flowcytometry (BD FACSCanto TM II). Intracellular content of RANTES was evaluated by<br />

flowcytometry and ELISA (Quantikine, R&D). Other chemokines and cytokines including IL-8, MCP-1<br />

and Eotaxin were measured by Bio-Plex Pro TM Assays, BIORAD).<br />

<br />

DARC was expressed on RBC of all the samples examined. RANTES was recognized in RBCs, but not<br />

on the surface. When compared the concentrations of IL-1β, TNF-α, VEGF, RANTES, Eotaxin MCP-1,<br />

IL-8 in the washed RBC supernatant be<strong>for</strong>e and after hemolysis, RANTES, Eotaxin and MCP-1showed<br />

marked increase after hemolysis. This finding showed that RBCs absorb chemokines which has high<br />

affinity to DARC. RANTES was absorbed by RBCs rapidly. Intracellular RATNTES concentration<br />

reached almost the maximum level within 15 minutes. DARC expression decreased in the presence of<br />

RANTES.<br />

<br />

RBC contains DARC-affinity chemokines. The role of RBCs in inflammation and immunological<br />

diseases awaits to be explored.<br />

Asian Thrombophilia: Dysfunction of the APC anticoagulation system.<br />

Naotaka Hamasaki, Hiroaki Kuma, Hinako Hatae<br />

Department of Clinical Chemistry, Faculty of Pharmaceutical Sciences, Nagasaki International<br />

University, Japan<br />

The anticoagulation system in a healthy individual is composed of mainly three systems, that is, (i)<br />

tissue factor pathway inhibitor, (ii) antithrombin, and (iii) activated protein C (APC). The APC<br />

anticoagulation system is unique in the sense that the anticoagulation activity is expressed only when<br />

thrombin is <strong>for</strong>med by the coagulation system and the APC activity is regulated proportionately to the<br />

coagulation activity.<br />

The thrombophilia common among Caucasians is the genetic polymorphism of coagulation factor<br />

V Leiden (R506Q). Factor V Leiden (R506Q) shows resistance to the APC anticoagulation system<br />

(APC-resistance). Because of this, factor V Leiden (R506Q) carriers have relatively stronger coagulation<br />

activity than the anticoagulation activity of APC, and is believed that this leads to excessive thrombus<br />

<strong>for</strong>mation and makes the person prone to thrombosis. Approximately 30% of Caucasian patients with<br />

venous thrombosis are carriers of factor V Leiden (R506Q) [1]. Unlike Caucasians, thrombophilias<br />

among Japanese and Chinese are the ones with dysfunction of the activated protein C (APC)<br />

anticoagulant activity caused mainly by abnormal molecules of protein S or of protein C<br />

(APC-dysfunction). Approximately 50% of Japanese and Chinese patients suffering from deep vein<br />

thrombosis have reduced activities of the APC anticoagulant system [2]. In other words, the<br />

APC-resistance in Caucasians and the APC-dysfunction in Japanese and Chinese are the major risk<br />

factor <strong>for</strong> thrombosis. Whether the APC-dysfunction occurs in other Asian countries is an important<br />

aspect of mapping thrombophilia among Asians, and international surveys would be needed to<br />

determine it. Combined with our investigation and results of other studies, we will review the Asian<br />

thrombophilia and indicate our strategy to overcome the “prone to thrombosis”.<br />

Great impact of the brand-new Sysmex XN-Series automated hematology analyzer<br />

on workflow efficiency and utility<br />

Etsuko Hamada, Masato Maekawa<br />

Department of Laboratory Medicine, Hamamatsu University School of Medicine, Hamamatsu, Japan<br />

Introduction:<br />

Recently, higher-quality testing environment has been increasingly required. To counteract these<br />

demands, Sysmex has introduced the XN-Series automated hematology analyzer. Here we report our<br />

evaluation results of the XN-Series basic per<strong>for</strong>mance and the integrated hematology testing system.<br />

Method: (1) Basic per<strong>for</strong>mance: We evaluated precision, linearity, correlation with a previous analyzer<br />

(XE-2100, Sysmex) and correlation with the manual method. (2) Usability: We evaluated the usability<br />

of newly introduced functions of CNA-NET, which include automated smear preparation, selection of<br />

specific sample and sample requiring manual count. Results: (1) Basic per<strong>for</strong>mance: Precision (CBC)<br />

was 0.42-5.21 (CV%), and linearity was confirmed up to WBC 378×10 9 /L, RBC 7.81×10 12 /L, HGB 235<br />

g/L, HCT 72.1%, and PLT 1,691×10 9 /L. The correlation coefficients (r) with the previous analyzer<br />

were CBC 0.998–0.981, WBC classification ratio 0.995-0.917 and reticulocyte ratio 0.978. The<br />

correlation coefficient of WBC classification ratio with the manual method was 0.612-0.987. In the<br />

evaluation using samples with WBC ≤ 0.5×10 9 /L, WBC precision was 7.75-8.21 (CV%) <strong>for</strong> Whole<br />

blood mode and 1.29-4.17 <strong>for</strong> Low WBC mode, and the good correlation with the manual method was<br />

observed. In the evaluation using samples with PLT ≤ 50×10 9 /L, the correlation coefficient between<br />

PLT-I (impedance) and PLT-F (fluorescence) was 0.973, and with the manual method was 0.975 <strong>for</strong><br />

PLT-I and 0.980 <strong>for</strong> PLT-F. (2) Usability: The number of analyzer operator to measure 700 samples/<br />

day decreased from 1.5 to 1 person. Conclusion: Basic per<strong>for</strong>mance of the XN-Series was satisfactory.<br />

Especially, precision and accuracy in the low number of WBC and PLT were excellent. There<strong>for</strong>e it is<br />

possible to report higher clinical value result with the automatic measurement method. Use of the<br />

automated re-testing function and the CNA-NET made reporting time and processing time reduced. The<br />

newly introduced integrated hematology testing system improved the quality of the clinical testing.<br />

There are various quantitative notations <strong>for</strong> molecule expression on cells, such as the percentage of<br />

positive expressing cells (PPC) and the mean fluorescence intensity (MFI). As to MFI, some evaluate<br />

only MFI-PF among cells in positive fraction (PF), which express blighter fluorescence than that of<br />

iso-type control anti-bodies, the others do MFI-PF&NF among cells in PF and negative fraction<br />

(NF).We had published that the MFI-PF&NF of CD11a and CD11b on CD34 positive cells(CD34+) in<br />

peripheral blood (PB) were inversely correlated to the yields of total collectedCD34+ be<strong>for</strong>e<br />

administration of granulocyte-colony stimulating factor (G-CSF). Although some authors have<br />

reported similar analysis, they represented the expressions of these adhesion molecules by PPC or<br />

MFI-PF. Thus, the direct comparison of these results was impossible. We have analyzed the<br />

significance of the change of PPC, MFI-PF and MFI-NF of CD11a and CD11b, and the correlations of<br />

the yield of PB graft (YPBG). No significant changes ware indicated with 2-way ANOVA in PPC<br />

neither by the number of days administrating G-CSF (Days), nor the YPBG, while there were<br />

significant changes in MFI-PF&NF. The same test indicated not only significant change of MFI-PF of<br />

CD11a by Days, but also that of MFI-NF of CD11a by YPBG. The significant correlation between the<br />

PPC and the YPBG was not shown. MFI-PFs of CD11a and CD11b on day -1 indicated significant<br />

inverse correlations with the YPBG. MFI-NFs of CD11a and CD11b indicated no significant<br />

correlations with the YPBG The value of the lower fluorescence, which derived from non-specific<br />

binding of anti-bodies, was commonly recognized as meaningless. The presenting results suggested that<br />

the value of the lower fluorescence area had some important mean in a certain situation.<br />

Among patients who take warfarin, the most commonly prescribed anticoagulant, there are great<br />

differences in the dose required <strong>for</strong> sufficient effect. Recent reports have shown that the<br />

polymorphisms of vitamin K epoxide reductase complex, subunit 1 gene (VKORC1) and cytochrome<br />

P450, family 2, subfamily C, polypeptide 9 genes (CYP2C9) are closely associated with the dose<br />

requirement of warfarin. In this study, we investigated factors related to the differences in the required<br />

dose of warfarin, with special attention to the polymorphisms of VKORC1 and CYP2C9.<br />

METHODS:<br />

Relations between the dose of warfarin and PT-INR, age, body weight and the polymorphisms of<br />

VKORC1 and CYP2C9 were studied in 86 stably anticoagulated patients with cardiovascular diseases.<br />

The polymorphisms of VKORC1 -1639 G>A and CYP2CP 1075 A>C were determined by PCR-RFLP<br />

method with the restriction enzymes NciI and KpnI, respectively.<br />

RESULTS:<br />

There was no significant relation between the dose of warfarin and PT-INR, age or body weight. The<br />

AA and GA genotypes of VKORC1 -1639 were found in 69 and 17 patients, respectively. The mean<br />

dose of warfarin required was significantly higher in the GA genotype (3.9 mg/day) than in the AA<br />

genotype (2.4 mg/day, p

T-cell acute lymphoblastic leukemia (T-ALL), a malignant proliferation of T-lymphoid blasts, represents<br />

15% of acute lymphoblastic leukemia. In contrast with B-cell ALL, patients with T-ALL have different<br />

chromosomal abnormalities and appear to have an unfavorable prognosis, leading to more intensive<br />

treatment. Chromosomal rearrangements in T-ALL usually involve breakpoints in bands where the<br />

T-cell receptor (TCR) genes are located; these are bands 14q11 (TCR-α and -δ genes), 7q32-36<br />

(TCR-βgene), and 7p15 (TCR-γ gene). Other chromosomal changes, specific or not of T-ALL, have also<br />

been observed. We report T-ALL with t(8;14)(q24.1;q32) similar to that seen in Burkett’s lymphoma.<br />

Flow cytometric analysis of bone marrow revealed CD2, CD3, CD7, cytoplasmic CD3, CD34, HLA-DR,<br />

CD13, and CD117. The phenotype was suggestive of T-ALL. RT-PCR screening <strong>for</strong> leukemia-related<br />

fusion transcripts (HemaVision; Bio-Rad Laboratories, CA) was negative. Mitoses were obtained only<br />

from spontaneously dividing cells in the absence of mitogens; 25 of the 30 metaphases analyzed were<br />

chromosomally abnormal and had a der(14)t(8;14)(q24.1;q32). Disruption of the MYC gene which<br />

resulted in a one fusion, one green, and one orange signal pattern was detected by MYC dual-color<br />

break-apart probe (Abbott Molecular, IL) PCR-based B-cell and T-cell clonality (Ig and TCR gene<br />

rearrangement) assays was studied by the BIOMED-2 multiplex Ig/TCRB PCR assay (InVivoScribe,<br />

CA) but did not detected any clonal immunoglobulin and TCR rearrangements. Although abnormalities<br />

involving 14q32 are characteristic of B cell disorders, they have also been described in T cell<br />

malignancies, suggesting that genes transcribed in T cells and/or oncogenic sequences significant in T<br />

cell neoplasia are present in 14q32.<br />

Department of Clinical Pathology, Faculty of Medicine Hasanuddin University, Makassar,<br />

Indonesia<br />

Malaria is an infectious disease caused by Plasmodium which is usually presenting fever. Microscopic<br />

examination is gold standard test to diagnose malaria, but sometimes there might be error in laboratory<br />

examination. Automated blood cell analyzer, <strong>for</strong> example, Sysmex XT2000i and XT1800i are<br />

automatically tools <strong>for</strong> complete blood count including leukocytes differentiation and can be used to<br />

suspect diagnosis of malaria early. Our case was a male patient of 44 years old who was admitted in<br />

Wahidin Sudirohusodo Hospital of Makassar with chief complaint of fever. On the first day of<br />

admission, stained blood film was negative <strong>for</strong> Plasmodium, but the Sysmex DIFF scattergram was<br />

abnormal. Based on these findings, complete blood count and stained blood film were per<strong>for</strong>med again<br />

and we found trophozoites, schizonts and gametocytes of Plasmodium falciparum and Plasmodium<br />

malariae. The second case a female patient of 37 years old had an abnormal DIFF scattergrams and we<br />

found Plasmodium vivax in both thick and thin blood films. The results indicated that abnormal DIFF<br />

scattergram of Sysmex analyzer could be used as an early clue or suspicion of Plasmodium infection,<br />

especially if patient presented with chief complaint of fever. Abnormal areas of eosinophils and cell<br />

ghosts as well as neutrophils in the DIFF scattergram may indicated the existence of Plasmodium<br />

malaria.<br />

Introduction Platelet size in<strong>for</strong>mation is helpful <strong>for</strong> differential diagnosis of the patients with<br />

thrombocytopenia. Although mean platelet volume (MPV) is most frequently employed as platelet<br />

size marker, occasionally MPV cannot be obtained mainly due to severe thrombocytopenia or widely<br />

spread platelet size distribution. Then we have studied the usefulness of platelet most frequent volume<br />

(P-MFV) as a surrogate platelet size marker. Materials and Methods Complete blood counts from<br />

hematologically normal 100 adults, 44 children, 43 newborn infants( birth weight > 2500g) and 23<br />

premature babies (birth weight < 2500g )were enrolled in this study by means of XE-2100 (Sysmex,<br />

Kobe, Japan). They were outpatients or newborn babies in Kakogawa West City Hospital, between May,<br />

2010 and May, 2012. Three patients with acute type immune thrombocytopenia, and one<br />

Wiskott-Aldorich syndrome were also included. Results The correlation efficiency between P-MFV and<br />

MPV was between 0.844 and 0.909 <strong>for</strong> all populations. P-MFV and MPV correlated very well in any<br />

Departments of Laboratory Medicine 1 , Pathology 2 and Internal Medicine 3 , University of Ulsan College<br />

of Medicine and Asan Medical Center, Seoul, Korea<br />

Background : Intravascular large B-cell lymphoma (IVLBCL) is a rare type of lymphoma characterized<br />

by the selective growth of neoplastic cells within blood vessel lumina. In Western countries, the brain<br />

and skin are the most common sites of disease. In Asian countries, mainly reported in Japan, the<br />

IVLBCL manifest itself more frequently with fever, hepatosplenomegaly, hemophagocytosis, bone<br />

marrow (BM) invasion, respiratory disturbance and disseminated intravascular coagulopathy. We aimed<br />

to analyze characteristics of IVLBCL in Korea.<br />

Methods : We retrospectively reviewed the records of 10 patients diagnosed as IVLBCL from January<br />

1997 to December 2011 in Asan Medical Center. BM aspiration smears and biopsy sections were<br />

obtained in 9 cases. H&E stain and Immunohistochemical stains (anti-CD3, anti-CD20, anti-CD79a and<br />

anti-CD34) were per<strong>for</strong>med on BM biopsies. And all cases were evaluated by Abdomen/Pelvis CT and<br />

Chest CT. Whole body PET or brain imaging was taken in some cases.<br />

Results : BM, lung and skin were frequently involved (3 cases, 4 cases, 2 cases, respectively).<br />

Hemophagocytosis was observed in only one case. Total 4 out of 10 patients expired (40%). Two<br />

patients with BM involvement suffered a relapse and expired (67%). Anti-CD20 and Anti-CD34<br />

immunohistochemical stain helped with the diagnosis of BM involvement<br />

Conclusion : Different clinical features from patients in Western countries or Japan. BM involvement<br />

seems to be a strong unfavorable prognostic factor. Anti-CD34 ICH could be helpful <strong>for</strong> detection and<br />

diagnosis of IVLBCL especially in cases with vague infiltration pattern on H&E stain.<br />

Department of Laboratory Medicine, university of Ulsan, College of Medicine and Asan<br />

Medical Center, Seoul, Korea<br />

Background: Several automated digital imaging systems have been introduced in recent years and<br />

showed excellent correlation with conventional manual and digital imaging differentials <strong>for</strong> the<br />

evaluation of peripheral blood smears. The aim of this study was to evaluate one of the modern<br />

automated digital imaging systems, the CellaVision DM96 (CellaVision AB, Sweden), <strong>for</strong> the<br />

examination of body fluid cytospin slides.<br />

Methods: We evaluated 101 body fluid cytospin slides from 91 patients. In the manual microscopic<br />

differentials, 62 cases had malignant effusion or leptomeningeal seeding, of which 47 had metastatic<br />

carcinoma and 15 had lymphoma or leukemia involvement. The remaining 39 cases showed benign<br />

conditions. Specimen types included 40 peritoneal fluid, 26 pleural fluid, 25 cerebrospinal fluid (CSF),<br />

5 bronchoalveolar lavage fluid, 3 dialysis fluid, and 2 pericardial fluid samples.<br />

Results: Results from the comparisons showed good correlation <strong>for</strong> all cell classes with correlation<br />

coefficients ranging from 0.643 to 0.998. Four CSF samples were not analyzed due to a very low<br />

number of total leukocytes (< 2 /μL). Strong correlation was observed with neutrophils, lymphocytes,<br />

macrophages and eosinophils with correlation coefficients greater than 0.8. However, correlation<br />

coefficients <strong>for</strong> mesothelial cells and malignant cells were slightly lower, with the values of 0.698 and<br />

0.643, respectively. More malignant cells were detected on manual microscopic examination than with<br />

the digital imaging system, with a mean difference of 13.5%. Notably, cases with benign effusion or<br />

CSF showed excellent correlation <strong>for</strong> all major cell classes, with correlation coefficients greater than 0.9.<br />

Correlation was unaffected by the leukocyte count in the fluid.<br />

Conclusions: Our evaluation of CellaVision DM96 revealed good correlation with manual microscopic<br />

differentials <strong>for</strong> evaluation of body fluid cytospin slides. Thus, this system can be an effective option <strong>for</strong><br />

body fluid analysis in hematology laboratories needing an automated digital imaging system. In<br />

particular, it can be used to rule out malignant effusion or leptomeningeal seeding as a first-line<br />

screening tool and can help improve workflow and reduce turnaround time.<br />

Calculation of Measurement Uncertainty <strong>for</strong> Complete Blood Cell Counts (CBC)<br />

Atsushi Shirakami, Masako Koguchi, Tsutomu Kakuyama, Kanako Kiso, Takashi Kitagawa<br />

Sysmex Corporation, Japan<br />

Recently, due to penetration of ISO standards (ISO 15189 1) ) and globalization of health services,<br />

medical laboratories are required to assure the reliability of testing results by showing its traceability<br />

and measurement uncertainty. To achieve it, ISO 17511 2) requires IVD manufacturers to establish the<br />

metrological traceability <strong>for</strong> the testing parameters to the end-users. For hematological testing<br />

parameters, such as CBC, there is no certified reference material (CRM) except <strong>for</strong> Hb – fresh blood<br />

sample is the only material that can transfer the data of the reference measurement procedure (RMP),<br />

which made the standardization of CBC results more difficult than clinical chemistry. We established the<br />

metrological traceability and the calculation methods of measurement uncertainty <strong>for</strong> the CBC 5<br />

parameters, WBC, RBC, Hb, Ht and Plt, based on the GUM 3) approach. The major data-transfer process<br />

in the manufacturer consists of the following three steps ;<br />

Step 1. Value assignment of five fresh blood samples with RMP<br />

Step 2. Calibration of standard analyzers with value-assigned fresh blood samples<br />

Step 3. Value assignment of product calibrator<br />

For each step, we evaluated the major uncertainty sources and calculated the measurement uncertainty<br />

by ANOVA and uncertainty budget. Then we assigned the values of the product calibrator with<br />

expanded uncertainty (coverage factor; k=2).So medical laboratory can assure the traceability and<br />

measurement uncertainty by calibrating the hematology analyzer with the product calibrator. However,<br />

as <strong>for</strong> utility of uncertainty in the routine laboratory test results <strong>for</strong> clinician, more discussion is<br />

necessary.<br />

Serum Thymidine Kinase 1 as a Potential Marker <strong>for</strong> Aggressive Behavior in<br />

Patients with B-cell Lymphoma<br />

Heyjin Kim, Jin Kyung Lee, Young Jun Hong, Seok-Il Hong, and Yoon Hwan Chang<br />

Department of Laboratory Medicine, Korea Cancer Center Hospital, Seoul, Korea<br />

Aim: B-cell lymphoma comprises a heterogeneous group of lymphoproliferative malignancies with<br />

various clinical and biological features. The cell cycle-dependent enzyme, thymidine kinase 1 (TK1) has<br />

been known as one of the markers of cancer cell proliferation and had been reported as a prognostic<br />

factor in various solid tumors and CLL. The aim of this study is to evaluate the usefulness of TK1 as a<br />

biomarker <strong>for</strong> aggressive behavior in patients with B-cell lymphoma.<br />

Methods: A total of 52 patients with previously untreated B-cell lymphoma (25 women, 27 men; age,<br />

14-86 years; median age, 62.5 years) and 43 healthy control subjects were enrolled in this study. TK1<br />

level in serum were measured by chemiluminescence immunoassay (LIAISON ® , DiaSorin, USA).<br />

Results: The 95 percentile reference range <strong>for</strong> serum TK1 in healthy controls was 4.5-18.6 U/L. There<br />

was a clear difference in mean TK level was shown between patients and healthy controls (46.8 ± 79.0<br />

vs. 9.9 ± 3.9 U/L, P = 0.003). The mean TK1 level of patients with bone marrow involvement was<br />

significantly elevated compared with that of patients without bone marrow involvement (128.8 +± 144.1<br />

vs. 29.6 ± 43.3 U/L, P=0.002). The mean TK1 level in the clinical stage III and IV group was<br />

significantly higher than that of the clinical stage I and II (85.1 ± 109.8 vs. 20.8 ± 28.9 U/L, P=0.016)<br />

group. The increased TK1 level at the time of diagnosis was correlated with the advanced clinical stage<br />

(P=0.000), international prognostic index score (P = 0.001), B symptoms (P = 0.035), hemoglobin level<br />

below 12.0 g/dL (P=0.004), and lactate dehydrogenase level above 480 U/L (P=0.000).<br />

Conclusions: These findings indicate an association between serum TK1 level and aggressive behavior<br />

of B-cell lymphoma. There<strong>for</strong>e, the TK1 level could serve as a valuable prognostic marker in patients<br />

with B-cell lymphoma.<br />

Taiwan<br />

Background: Human herpes virus type 8 (HHV-8) DNA is found consistently in all types of Kaposi’s<br />

sarcoma (KS), which is sometimes seen in human immunodeficiency virus (HIV) non-infected patients<br />

with immunologic abnormalities. Lung carcinoma is one of the most common malignancies developing<br />

in immunocompromised patients. However, the prevalence of HHV-8 infection in lung carcinoma<br />

patients is unclear.<br />

Methods: Blood samples were collected from 109 lung carcinoma patients with malignant pleural<br />

effusion and 109 age-matched healthy controls and analyzed <strong>for</strong> lymphocyte and monocyte counts, and<br />

presence of HHV-8 antibody and DNA. All study subjects were negative <strong>for</strong> anti-HIV antibodies.<br />

Results: Lung carcinoma patients had significantly lower mean lymphocyte counts and significantly<br />

higher monocyte counts than the healthy controls (P < 0.001). Three patients with lymphopenia and<br />

stage IV tumor were positive <strong>for</strong> HHV-8 DNA, one of them was negative <strong>for</strong> HHV-8 antibody. HHV-8<br />

positivity was significantly higher in patients (42.2%), particularly in male patients (50.8%), than in<br />

healthy controls (24.8%) (P = 0.006 and < 0.001, respectively). HHV-8 positivity was significantly<br />

greater in male patients than in female patients (29.5%) (P = 0.028). HHV-8 antibody titers in patients<br />

also significantly exceeded those in healthy controls (P = 0.004). All subjects positive <strong>for</strong> HHV-8 were<br />

not associated with clinical manifestations of HHV-8 infection.<br />

Conclusions: HHV-8 seroprevalence was significantly greater in lung carcinoma patients than in<br />

healthy controls, and associated with gender.<br />

As the prevalence of HIV infection increases, the problem of discordant couples with HIV arises.<br />

Although the number is yet unknown, discordant couple presented problem of possible infection to the<br />

mothers and unborn babies. In this study, we assessed the utilization of nucleic acid sequence based<br />

amplification (NASBA) to quantify HIV-1 RNA in seminal fluid, and reported the HIV-1 RNA viral<br />

load in the seminal fluid of patients with discordant couple from the outpatient clinic of Dharmais<br />

Cancer Hospital during July 2010 – February 2012, who have already been successfully treated with<br />

antiretrovirals (ARV).<br />

To determine the usefulness of NASBA, RNA from 2 unprocessed seminal fluid specimens were<br />

extracted using the MiniMag®, amplified by NASBA, and the result quantified. To verify the usefulness<br />

of sperm washing, we processed specimen with high HIV-1 RNA with gradient centrifugation to wash<br />

the sperm, and quantified the viral load in the resulting seminal plasma from first centrifugation, and the<br />

supernatant and sperm from the second washing. After optimization, we evaluated the result of 43<br />

patients treated with ARV who were referred <strong>for</strong> HIV-RNA in seminal fluid test.<br />

HIV-1 RNA was detected in the unprocessed seminal fluid (Pt#1 19,000 IU/ml; pt#2 740 IU/ml), and<br />

in the seminal fluid from the first centrifugation. Supernatant and sperm from the second washing<br />

showed HIV-RNA below detection limit. The result proved that boom extraction and NASBA principle<br />

can be used <strong>for</strong> quantification of HIV-RNA in seminal fluid, and that sperm washing was effective to<br />

minimize the risk of infection in assisted reproduction, but this needed to be verified with more samples.<br />

All 43 patients showed HIV-RNA below detection limit (

Objectives: Detection of carrier state of meningococcal infection and study of their distribution in<br />

different area of Ulaanbaatar city <strong>for</strong> the period of January – April 2011.<br />

Materials and Methods: 4720 throat swabs were collected and inoculated on Thayer – Martin agar<br />

medium, as used <strong>for</strong> primarily isolating Neisseria meningitides and as the medium that inhibits the<br />

growth of the most other microorganisms. Biochemical properties of the isolated strains characterized<br />

on medias, enriched with different carbohydrates such as glucose, maltose, saccharose and lactose.<br />

Standardized methods have been used <strong>for</strong> testing of oxidase activity and serological typing.<br />

Results: For the period of 2005 – 2010 registered several cases of spreads of meningococcal meningitis<br />

in the city, preceded by increase of “healthy” carriers of meningococci, who considered as the source of<br />

spreads to the surrounding people. 514 samples give growth of the N. meningitides, where serogroup B<br />

detected as most prevalent type (69.74%), followed by serogroup C (10.3%) and serogroup A as the<br />

lowest type (0.19%), with irregularity in distribution in different parts of the city.<br />

Highest positivity of carrier states were revealed geographically in Sukhbaatar and Bayan – Gol districts<br />

as taken together (70% of the total growth), and peak of the positivity of months of January and<br />

February followed by marked decline in the month of April. Age group of positivity falls between 0 and<br />

7 years (65%), as expected and most of them were from kinder garden and only 27 kids were from home<br />

staying places.<br />

Conclusion: 1. Serogroup B is the main type (~70%) of the meningococcal strain in Ulaanbaatar city<br />

and serogroup A is the least one (0.19%), with no registered serotype of D and Y. 2. Epidemiologically<br />

important carrier states were detected mostly in children visiting communal institutions like kinder<br />

gardens and schools (405 cases) and were characterized by seasonal and geographical differences in the<br />

Objectives: The level of sHLA class I molecules in human sera is markedly increased after BM and<br />

organ transplantation, viral infections, autoimmune disorders and cancer. Their biological and clinical<br />

significance has not been fully studied. In the present study the effects of soluble HLA (sHLA) class I<br />

molecules against EBV-specific CTL were examined.<br />

Materials and Methods: Two different sources of sHLA class I, either bioengineered spliced <strong>for</strong>m of<br />

HLA-B7 (sB7) or natural production from EBV-trans<strong>for</strong>med B cells (natural sHLA), were added during<br />

the induction of CTL or incubated with MHC-restricted CD8+ CTL, which were selected by<br />

immunobeads just be<strong>for</strong>e testing <strong>for</strong> their cytotoxic activity.<br />

Results: Both sB7 and natural sHLA class I blocked the generation of CD+ CTL and also inhibited the<br />

cytotoxic activity of established CTL in a dosedependent manner. In both ways, natural sHLA class I<br />

was effective in 10-fold lover concentrations compared with sB7. The inhibitory effect did not require a<br />

shaping of the HLA allotypes between sHLA and the CTL. CTL, after being treated with sHLA,<br />

underwent apoptosis, which was considered here as the main mechanism. Generally, sHLA class I<br />

consists of three different molecular <strong>for</strong>ms: a shedding <strong>for</strong>m with a heavy chain of 44 kD, a splicing<br />

<strong>for</strong>m with a heavy chain of 35 kD and 37 kD. All these molecules are associated with β2-microglobulin.<br />

Also it was reported that membrane-derived, naturally occurring sHLA class I <strong>for</strong>ms multimers through<br />

the ydrophobic<br />

transmembrane tail, whereas cytosol-derived sHLA class I cannot <strong>for</strong>m aggregates. In our studies, the<br />

naturally sHLA class I consisted of all three different molecular <strong>for</strong>ms of HLA-B7.<br />

Conclusion: The naturally occurring sHLA class I induces apoptosis more markedly than sB7. supports<br />

the same suggestion that the membrane -derived naturally occurring sHLA class I could cross-link with<br />

TCR/CD3 complexes via its multimeric <strong>for</strong>ms, and it probably leads to more effective apoptosis of the<br />

CTL. The difference in the biochemical nature of sHLA class I molecules might be the reason why the<br />

inhibitory effect of naturally occurring sHLA class I as stronger than that of sB7.<br />

Screening and targeted testing <strong>for</strong> tuberculosis (TB) is a key strategy <strong>for</strong> controlling and preventing<br />

infection on university campus and teaching hospital. The Mycobacterium tuberculosis antigen-specific<br />

interferon-γ release assays (IGRAs) are used to detect latent tuberculosis infection. In Japan, it is<br />

desirable to obtain basal data of IGRAs in medical school students and international students. To<br />

evaluate tuberculosis risk in university campus and medical school at course entry, retrospective study<br />

was per<strong>for</strong>med. One thousand two hundred seventy-one students (887 medical students and 384<br />

international students in Gunma University) underwent QunatiFERON-TB Gold test (QFT-TB) or<br />

QunatiFERON-TB In-Tube test (QFT-GIT) at course entry. Eight of 887 medical students (0.9%) were<br />

positive <strong>for</strong> QFT-TB or QFT-GIT, and none was diagnosed to have active tuberculosis among positive<br />

students. Thirty of 384 international students (7.8%) were positive <strong>for</strong> QFT-GIT, and 2 students of 30<br />

QFT-GIT positive students (6.7%) were diagnosed active tuberculosis during follow up. Positive ratio of<br />

QFT-GIT in international students of Gunma University was significantly higher than that of medical<br />

students. We propose tuberculosis screening with QFT-GIT test as a standard approach <strong>for</strong> medical<br />

as E-test®, VTEK2® and Broth microdilution (BMD). Methods: E-test® ,VITEK2® and BMD were<br />

applied <strong>for</strong> measuring VCM MIC in consecutive 59 MRSA strains isolated from blood cultures of 59<br />

patients between 2007 and 2012. The tests results were categorized to binary variables using cut-off<br />

value of 2.00μg/ml to calculate the kappa statistic. The annual change of prevalence of VCM resistant<br />

MRSA was tested by Fisher’s exact test.<br />

Results: MRSA were isolated from blood cultures in 28 cases in 2008,12 cases in 2009, 9 cases in 2010,<br />

and 10 cases in 2011. The prevalence of strain with VCM MIC 2.0μg/ml using BMD method was 14%<br />

in 2008, 28.6% in 2009, 0% in 2010, and 10% in 2011. There was no significant annual change in the<br />

prevalence of VCM resistant MRSA (P=0.23 by Fisher’s exact test).The proportion of strain with MIC<br />

2.00μg/ml of BMD, VITEK2® and E-test® method was 15.2%, 0.5% and 59%, respectively. The kappa<br />

statistic of three tests was 0.12. Conclusion: There is no significant change in the prevalence of MRSA<br />

with high VCM MIC (=2.0) measured by BMD method from 2008 to 2011. Comparing to BMD method,<br />

VITEK2® method tends to miss MRSA with high VCM MIC (=2.0). On the other hand, E-test®<br />

method tends to overdiagnose MRSA with high VCM MIC (=2.0). The differences between tests’<br />

characteristics should be taken into account <strong>for</strong> clinical implication<br />

Mycobacterium kyorinense is a nonpigmented, slowly growing mycobacterium that was initially<br />

isolated in 2007. Biochemical tests and genetic analyses showed that M. kyorinense is most closely<br />

related to M. celatum and M. branderi. We here describe 7 newly identified cases with 4 previously<br />

reported cases, in which infection potentially was caused by M. kyorinense. In reviewing these 11 cases<br />

(10 Japanese and 1 Brazilian), 9 presented with respiratory infections, 1 with lymphadenitis, and 1 with<br />

arthritis. Seven patients were treated by first-line tuberculosis drugs, mainly consisting of rifampin,<br />

isoniazid, and ethambutol, but these therapies were ineffective in all cases. Six cases were treated with a<br />

combination of antibiotics including macrolides and fluoroquinolones as a first- or second-line<br />

chemotherapy, and infection was subdued without recurrence in 5 cases. In contrast, 4 pneumonia<br />

patients who did not receive sufficient therapy with the latter regimen eventually died of infection. In<br />

concordance with the clinical antimicrobial susceptibility, most strains exhibited relatively high MICs<br />

<strong>for</strong> rifampin, ethambutol, and isoniazid, and relatively low MICs <strong>for</strong> macrolides, aminoglycosides, and<br />

quinolones. Notably, remarkably high MICs (>32 �g/ml) w<br />

Direct sequencing of the 16S rRNA gene revealed that all available M. kyorinense isolates were<br />

identical within this gene, except <strong>for</strong> the Brazilian strain which showed slight difference with other<br />

Japanese isolates. Direct sequencing of the entire rpoB gene demonstrated that all strains had identical<br />

sequences, with Ser531 in the M. tuberculosis RpoB protein replaced by an Asp in M. kyorinense.<br />

Notably, Ser531 is the most frequent location of substitutions in rifampin-resistant strains of M.<br />

tuberculosis. These data suggest that M. kyorinense belongs to non-tuberculous mycobacteria that have<br />

pathogenicity <strong>for</strong> humans with substantial clinical significance, and that M. kyorinense is inherently<br />

resistant to rifampin due to the structural features of its RpoB protein.<br />

University Hospital, Korea<br />

The Lecythophora species are very rare pathogen to human reported as subcutaneous abscess, corneal<br />

infection, endophthalmitis, sinusitis, peritonitis, and endocarditis, and cannot found the clinical case<br />

especially caused by Lecythophora hoffmannii in Korea. So we introduce the first case of L. hoffmanni<br />

peritonitis infection in Korea.<br />

A 79-year-old female had a medical history of end stage of renal disease (ESRD) with continuous<br />

ambulatory peritoneal dialysis (CAPD) was hospitalized <strong>for</strong> abdominal pain with diarrhea and anorexia<br />

at June 2012. Initial WBC counts were 11.9 x 10 3 /uL, Hb was 11.1 g/dL, and platelet were 643 x 10 3 /uL.<br />

ESR were 104 mm/hr and BUN and Cr were 61.8 and 6.6 mg/dL, respectively. The abdominal CT<br />

showed sclerosing encapsulating peritonitis, so she treated by experience antibiotics. Cultures was done<br />

with 7 peritoneal fluid samples from June 13 to July 16, same fungus was growth all samples. The rate<br />

of growth is average 4 days at 30C. The colony morphology was smooth, moist to slimy yeast like, with<br />

fuzzy. It shows yellow-orange to salmon pink colors. Reverse is yellow to orange. In microscopic, yeast<br />

like conidia were significantly noted and a few hyaline, septated hyphae were seen. It was not identified<br />

used by yeast card of VITEK II system (Biomerieux, French). So the 26S rRNA sequencing was done<br />

and identified as Lecythophora hoffmannii.<br />

Sensitive, one, two-drug resistance, and MDRP Pseudomonas aeruginosa integron<br />

carrying rates<br />

Daisuke Tanabe<br />

Bunkyo Gakuin University graduate school, Japan<br />

Pseudomonas aeruginosa is pathogenic bacteria isolated high frequency to cause opportunistic infection.<br />

Since the introduction of antibiotics in the treatment of P. aeruginosa infection, antibiotic resistance<br />

has spread quickly among bacteria. Such explosive dissemination is a consequence of the mobility of<br />

the antibiotic resistance encoding genes, which are usually found in integrons. That resistance<br />

mechanism called integron structures is associated with the insertion of resistance genes into cassette<br />

region. Although, the analyses of integron structures of MDRP has been reported, the analyses of<br />

sensitive, one, and two-drug resistant isolates has less reported. The purpose of this study is to analyze<br />

integron structures of P. aeruginosa and to investigate carrying rates. P. aeruginosa was used 96<br />

clinical isolates from hospitals located in the Kanto area. Susceptibilities which used 10 antimicrobial<br />

agents was determined by MIC testing in reference to Clinical and Laboratory Standards Institute<br />

(CLSI). SMA disk was used to screen <strong>for</strong> Metaro β-lactamase producing (MBL) isolates. PCR<br />

analyses <strong>for</strong> the detection of MBL genes were carried out <strong>for</strong> all strains <strong>for</strong> which the screening test<br />

using SMA disks gave positive results. Furthermore, class 1,2,3 integrons were per<strong>for</strong>med all isolates<br />

according to the method reported by Senda. From the Susceptibility testing result, P. aeruginosa was<br />

separated into 4 classes (sensitive, one, two-drug resistant, and MDRP) according to MDRP criteria of<br />

CLSI (2010) (IPM 16µg/ml, CPFX 4µg/ml, and AMK 32µg/ml). There were Forty-six, twenty, sixteen,<br />

fourteen, respectively. Thirty isolates were carried class 1 integron; two of 46 sensitive isolates, 7of 20<br />

one-drug resistance, 8 of 16 two-drug resistance, and 13 of 14 MDRP. In this present study, the parts of<br />

sensitive, one , and two-drug resistance isolates carried class 1 integrons. It is considered that<br />

non-MDRP may be able to change MDRP according to insert resistance genes into integrons.<br />

【Purpose】MALDI-TOF MS-based strain typing <strong>for</strong> microorganisms is a fast and inexpensive<br />

technology <strong>for</strong> identification of bacteria. We introduced MALDI Biotyper Ⓡ (Bruker Daltonics Inc,) as a<br />

clinical diagnostic system <strong>for</strong> microbial infection since April this year. The system needs only 10<br />

minutes from isolation of the target colonies and considerably accurate compared with genomic analysis<br />

using 16S rRNA. We applied this system to characterize the epidemiological relationships among<br />

bacterial strains.<br />

【Samples and Methods】24 of MRSA and 48 of Pseudomonas aeruginosa strains, those genomic<br />

pattern determined by pulsed-field gel electrophoresis (PFGE), were analyzed by MALDI Biotyper, and<br />

the characteristic amino acid profiles were assessed by ClinProTools. For extraction of the proteins from<br />

bacteria, an ethanol-<strong>for</strong>mic acid extraction method was used, and the assays were conducted by<br />

duplicate to obtain confirmative spectra. The spectra were analyzed by using ClinProTools (Bruker<br />

Daltonics Inc.). ClinProTools is designed to facilitate the processing and comparison of multiple spectra<br />

from each bacterium by automatically normalizing, baseline subtracting, peak defining, and<br />

recalibrating.<br />

【Results】We compared the results obtained from MALDI-TOF MS combined with ClinProTools and<br />

those from PFGE. The epidemiological relationships examined by MALDI-TOF MS and PFGE among<br />

MRSA and Pseudomonas aeruginosa strains were almost identical. The results were validated with<br />

other molecular epidemiological examinations.<br />

【Conclusion】The epidemiological relationships examined by MALDI-TOF MS showed comparable<br />

data with PFGE. Since MALDI-TOF MS-based strain typing <strong>for</strong> microorganisms is a fast and<br />

inexpensive technology <strong>for</strong> identification of bacteria, the technique combined with ClinProTools is<br />

thought to be a useful tool <strong>for</strong> molecular epidemiological relationships among bacterial strains.<br />

Simultaneous inhibition of NF-κB and caspase-1 by a cell-permeable compound<br />

DHMEQ leads to potent suppression of IL-1β<br />

Sayaka Ito, Misako Iwata, Tetsuo Kubota<br />

Graduate School of Health Care Sciences, Tokyo Medical and Dental University, Japan<br />

Objective: A rare autoinflammatory disorder, cryopyrin-associated periodic syndromes (CAPS), is<br />

caused by uncontrolled secretion of IL-1β leading to recurrent inflammatory attacks. To develop a novel<br />

therapeutic strategy <strong>for</strong> CAPS, we studied an effect of a cell-permeable compound (-)-dehydroxy methyl<br />

epoxy quinomicin (DHMEQ) in an in vitro assay system <strong>for</strong> IL-1β production.<br />

Methods: Peripheral blood mononuclear cells (PBMCs) from patients with CAPS and healthy<br />

volunteers were primed <strong>for</strong> 3h with LPS, followed by stimulation with ATP, and secreted IL-1β was<br />

measured by ELISA. DHMEQ (provided by Dr. Umezawa, Aichi Medical University) was added at<br />

different time points to examine the effect on expression of IL-1β and activation of caspase-1. Activated<br />

caspase-1 was detected by fluorescent staining using FAM-Tyr-Val-Ala-Asp-FMK. Caspase-1 and IL-1β<br />

in the cell lysates and culture supernatants were detected by western blotting. Recombinant caspase-1<br />

enzyme activity was measured by colorimetry using Ac-Tyr-Val-Ala-Asp-pNA.<br />

Results: Normal PBMCs secreted IL-1β only after ATP stimulation following LPS priming. In contrast,<br />

CAPS patients’ PBMCs secreted IL-1β even without ATP stimulation. In both cases DHMEQ effectively<br />

suppressed IL-1β secretion when it was added to the culture be<strong>for</strong>e LPS priming. Western blotting<br />

revealed suppression of proIL-1β expression during the LPS priming, which was thought to be one of<br />

the mechanisms of the effect. In addition, when we added DHMEQ after expression of proIL-1β, it<br />

significantly inhibited IL-1βsecretion. Results of western blotting and cytostaining suggested that<br />

DHMEQ inhibited activation of caspase-1. In a cell-free system, DHMEQ inhibited the enzyme activity<br />

of recombinant caspase-1 in a dose dependent manner.<br />

Conclusion: DHMEQ is a derivative of an antibiotic epoxy quinomicin C, designed <strong>for</strong> the NF-κB<br />

inhibitory activity. In addition, we found herein the inhibitory effect of DHMEQ on caspase-1 resulting<br />

in a potent suppression of IL-1β secretion without significant cytotoxicity. DHMEQ might be a good<br />

candidate drug <strong>for</strong> clinical application in therapy of CAPS.<br />

Dharmais Cancer Hospital Clinical Pathology Laboratory, Indonesia<br />

HIV-AIDS is a major healthcare problem in Indonesia, due to increasing prevalence, lifelong therapy,<br />

and high cost <strong>for</strong> monitoring. Monitoring of therapy requires HIV-RNA quantification, which is<br />

expensive and requires special equipment, dedicated room and skilled man power. A novel real-time<br />

PCR system (Existation) had been developed, which enabled real-time measurement of HIV-1 RNA<br />

in small to medium laboratory. We evaluated the per<strong>for</strong>mance of this system as compared to the<br />

reverse-transcriptase PCR (Cobas Taqman) and nucleic acid-based sequence amplification/ NASBA<br />

(Nuclisense). Fifty nine plasma samples were run on both Cobas Taqman and Existation, and 30<br />

plasma samples run on Nuclisense and Existation. The result of HIV-1 RNA viral load were<br />

analyzed descriptively. Of the 59 samples, 38 were not detected with Cobas Taqman (lower detection<br />

limit 33 IU/ml), and 3 of the 21 positive samples were below 400 IU/ml; 33 samples showed negative<br />

result from both plat<strong>for</strong>ms; 17 positive samples showed good agreement with the result of Existation<br />

Aim: We measured procalcitonin (PCT) and C-reactive protein (CRP) in patients with extended<br />

spectrum beta lactamase (ESBL)-negative bacteremia and analyzed the results according to clinical<br />

status of the patients. Materials and Methods: A total of 100 patients who were ESBL-negative<br />

bacteremia were analyzed. Among measured database, data from first and last tests of PCT (PCT1,<br />

PCT2) and CRP (CRP1, CRP2) during hospital stay were evaluated. PCT levels were measured by the<br />

VIDAS ® BRAHMS PCT assay, and CRP concentrations were determined by a turbidimetric assay using<br />

CA-400 analyzer. Results: The levels PCT1 of patients with community acquired infection (n=65) were<br />

more significantly higher than those with nosocomial infection (n=35) (12.6 ng/mL vs. 1.5 ng/mL,<br />

p=0.0001). Clinically, PCT1 levels were significantly higher in patients with central line insertion<br />

(p=0.0089), pneumonia (p=0.0233) and intensive care unit admission (p=0.0258) than in patients<br />

without these conditions. CRP2 levels were significantly higher in patients with intubation (p=0.0064),<br />

leukocytosis at the admission (p=0.0081) and urinary tract infection (UTI) (p=0.0198). The higher<br />

levels of PCT2 were shown in patients with mortality (p=0.0005) and UTI (p=0.0198). Similarly,<br />

Introduction: Influenza virus has been recognized as one of the most pandemic infectious disease agent.<br />

Rapid diagnosis of influenza is commonly per<strong>for</strong>med with immunochromatography method (IC) using<br />

specimens taken from upper respiratory tract. Although IC is easy and relatively cheap, its sensitivity<br />

is not perfect especially in early stage of disease because of low concentration of virus antigens.<br />

Applying a newly developed “silver amplification” principle, we generated a new assay method to<br />

increase sensitivity. The aim of this study is if our method has higher sensitivity and specificity than<br />

conventional IC assays.<br />

Materials and Methods: One hundred and twenty cases of influenza-like symptoms; fever, rhinorrhea,<br />

cough, and/or general fatigue who visited pediatrics department of our hospital from November 2011 to<br />

April 2012 were entitled. Cotton swab specimens were applied to Fuji Drychem IMMUNO AG1 TM<br />

(FUJIFILM Medical, Tokyo, Japan). Simultaneously, a conventional IC method was per<strong>for</strong>med with<br />

Quick Chaser FLU A/B TM by Mizuho Medy (Tosu, Japan). A real time PCR with TaqMan probe was<br />

also done <strong>for</strong> gold standard. This study was authorized by local ethic committee and written in<strong>for</strong>med<br />

consent was obtained from all the cases.<br />

Results: With silver amplification method, 23, 15 cases were influenza A, B positive, respectively. On<br />

the other hand, 23, 8 cases were A, B, positive with conventional assays. All the cases, which showed<br />

positive in new, negative in conventional influenza B assays, PCR results were positive. Their virus<br />

concentration ranged 10 5 to 10 9 copies/ml.<br />

Discussion: Specificity and sensitivity <strong>for</strong> influenza A was not different between the two assays.<br />

However, the silver amplification method showed higher sensitivity <strong>for</strong> influenza B. Because the new<br />

method applies photo-developing principle, its sensitivity was reported to increase 8 to 16 times,<br />

theoretically. This analyzer is small (18x20x11 cm) and light (1.8kg), it is suitable <strong>for</strong> bedside testing.<br />

Since number of cases is limited, more data are required to confirm the result.<br />

Conclusion: Our novel assay method using silver amplification has high potentiality to increase<br />

sensitivity of rapid bedside testing especially <strong>for</strong> influenza B.<br />

Comparison of four portable apnea recording devices in daytime screening session<br />

<strong>for</strong> severe sleep apnea patients screening<br />

Department of Laboratory Medicine, Teikyo University School of Medicine, Japan<br />

Evaluation <strong>for</strong> sleep apnea syndrome (SAS) in patients with cardiovascular problems is recommended in<br />

several existing guidelines. Although overnight polysomnography (PSG) is the golden standard <strong>for</strong> the<br />

evaluation, access to the examination is limited because it requires special institution and trained<br />

technicians. There<strong>for</strong>e, many portable recording devices with SpO2 monitoring only and those with<br />

SpO2 and airflow monitoring capability are developed <strong>for</strong> SAS screening. We constructed a daytime<br />

SAS screening session using portable devices to find out SAS patients during routine clinic visit of<br />

patients with cardiovascular problems. The subjects were asked to remain quiet and in a supine position<br />

in a dark room during the session <strong>for</strong> about 30 min. The present study evaluated the usefulness of four<br />

portable devices in detecting severe SAS cases through the screening session. The four devices are a<br />

thermister airflow-sensor type device (FM-500, Fukuda-denshi, Japan), two pressure airflow-sensor type<br />

devices (LS-300, Fukuda-lifetech; Morheus, Teijin, Japan), and a sheet-type device that detects chest<br />

wall movement (SD-101, Suzuken, Japan). Two hundred and ten patients underwent PSG after the<br />

screening session using one of the portable devices. We compared the respiratory disturbance index<br />

(RDI) measured in the sessions and apnea-hypopnea index (AHI) measured by standard PSG per<strong>for</strong>med<br />

afterward. The RDI by all devices and AHI correlated significantly. ROC analysis revealed that the<br />

thermister type device and sheet type devices had larger area under the curve (0.78 and 0.77,<br />

respectively) than two pressure sensor type devices (0.71 and 0.73) in detecting severe SAS patients<br />

(AHI in PSG≧ 30). The difference might be related to condition of airflow recording under nasal<br />

obstruction, as mouth breathing could not be monitored by the pressure type sensor in 8 cases. The<br />

results suggested that portable recording devices usable under nasal obstruction would be suitable <strong>for</strong><br />

SAS screening session.<br />

Aim: The aim of the present study was to investigate the utility of atherosclerotic evaluation of brachial<br />

and radial arterial wall elasticity (AWE) by the phased tracking method in patients with type 2 diabetes<br />

mellitus (T2DM).<br />

Methods: This hospital-based cross-sectional study included 244 patients with T2DM(males: 61%,<br />

mean age: 60 years). The patients were classified by vascular manifestations including a history of<br />

celebrovascular disease, coronary artery disease, diabetic retinopathy and nephropathy. The smoking<br />

habits, body mass index (BMI), blood pressure (BP), hemoglobin A1c, serum low-density lipoprotein,<br />

high-density lipoprotein, triglyceride, creatinine, and brachial and radial AWE were recorded.<br />

Differences of brachial and radial AWE by the progression of vascular manifestations were analyzed.<br />

Results: A total of 121 patients had vascular manifestations (50%). In the univariate analyses, a<br />

significant correlation was detected between brachial AWE and BMI (r = 0.30), systolic BP (r = 0.41),<br />

creatinine (r = 0.19), high-density lipoprotein (r = -0.17) and triglyceride (r = 0.14). Radial AWE had a<br />

significant correlation with BMI (r = 0.38), systolic BP (r = 0.48), creatinine (r = 0.19) and triglyceride<br />

(r = 0.18). These correlations were not largely altered in patients with or without vascular<br />

manifestations. Brachial and radial AWE of patients with vascular disease were significantly higher than<br />

those of patients without vascular manifestations (brachial AWE, 791 ± 236 kPa [Pascal] and 682 ± 215<br />

kPa, p < 0.01; radial AWE, 752 ± 245 kPa and 633 ± 209 kPa, p < 0.01). Receiver operating<br />

characteristic curve of boundary value of brachial and radial AWE revealed an area under the curve to<br />

Background: Ganglioglioma (GG) is an uncommon brain parenchymal neoplasm. Although most cases<br />

have indolent clinical behavior, a subgroup of GGs with anaplastic change in the glial component has<br />

aggressive behavior and less favorable outcome. O6-methylguanine DNA methyltransferase (MGMT)<br />

is a DNA repair protein that removes mutagenic and cytotoxic adducts from O6-guanine in DNA. Lack<br />

of MGMT protein expression immunohistochemically is related to drug responses in patients of<br />

malignant glioma treated with alkylating agents. EGFR is the most frequently amplified gene in<br />

glioblastoma and associated with tumor invasiveness, angiogenesis, poor survival, and resistance to<br />

radiation therapy. To elucidate the relationship between the statuses of the MGMT as well as EGFR<br />

proteins and the tumor grading and prognosis, we conduct this study.<br />

Methods: Clinicopathologic and immunohistochemical study of nine cases was per<strong>for</strong>med.<br />

Results: This series included four men and five women with a mean age of 21.4 years at first surgery.<br />

Immunohistochemically, the MGMT and EGFR protein expressions tended to be more intensive in<br />

anaplastic GG, corresponding to the worse prognostic predictive value of 3+ MGMT and 2+ EGFR<br />

staining in glial cell component, as well as 1+ EGFR staining in neuronal cell components.<br />

Conclusions: The series showed that MGMT and EGFR protein expressions tended to be more<br />

intensive in anaplastic ganglioglioma.<br />

Recently, HER2/neu becomes a molecular target <strong>for</strong> treatment of gastric carcinomas with a monoclonal<br />

antibody trastuzumab. However, evaluation of HER2/neu amplification and overexpression are not<br />

easy because of their intratumoral heterogeneities that are more frequent in gastric carcinomas than in<br />

breast carcinomas. In this study, using gastric carcinomas that showed HER2/neu-amplification at<br />

least in part, we immunohistochemically analyzed heterogeneities in HER2/neu expression.<br />

This study was based on the analysis of 72 surgically resected gastric carcinoma cases (35 early and 42<br />

advanced lesions). First, fluorescence in situ hybridization (FISH) was per<strong>for</strong>med in all 77 lesions.<br />

Then, H&E and immunohistochemical stainings with the monoclonal antibodies MUC5AC, MUC6,<br />

CD10, MUC2, CDX2, HER2/neu and p53 were carried out in the HER2/neu-amplified cancers.<br />

Twelve out of 62 in<strong>for</strong>mative cancers were HER2/neu-amplified (19.4%). HER2/neu overexpression<br />

was homogeneous in 2 cancers, heterogeneous in 9 cancers and negative in 1 cancer. Seven, 5 and<br />

none of the cancers were differentiated type, mixed differentiated and undifferentiated type and<br />

undifferentiated type, respectively. The depth of invasion was the mucosa in 5 cancers, the submucosa<br />

in 1 cancer and the muscularis propria or deeper in 6 cancers. p53 overexpression was diffuse in 8<br />

cancers, focal in 1 cancer and negative in 3 cancers. Phenotype was intestinal in 5 cancers, mixed<br />

gastric and intestinal in 6 cancers and null in 1 cancer.<br />

HER2/neu-amplified gastric carcinomas often showed heterogeneous overexpression <strong>for</strong> HER2/neu<br />

(75%) and diffuse overexpression <strong>for</strong> p53 (66.7%) and did not show pure gastric phenotype or<br />

undifferentiated type in the present study.<br />

A 73-year-old woman showed marked exophytic growth of a tumor (25 × 23 × 14 mm) of the nipple<br />

over a period of 2 months. Histologically, numerous tumor nodules with no apparent keratinization were<br />

observed in the exophytic lesion. The tumor cells also showed little invasion to the dermis and no<br />

metastasis to the axillary lymph nodes (LN). The tumor cells were immunohistochemically positive <strong>for</strong><br />

cytokeratins (CKs; AE1/AE3 and 34bE12), epithelial membrane antigen (EMA) and p53, but negative<br />

<strong>for</strong> Ber-EP4 and human papilloma virus (HPV). The MIB-1 index was 56%. Some tumor cells were also<br />

positive <strong>for</strong> some neuroendocrine markers, and showed some tonofilaments and neurosecretory granules<br />

in the cytoplasm under electron microscopy. We made the differential diagnosis of mammary ductal<br />

carcinoma, basal cell carcinoma (BCC), Paget’s disease, and neuroendocrine carcinoma including<br />

Merkel cell carcinoma. The final diagnosis was poorly differentiated squamous cell carcinoma (SCC)<br />

showing exophytic growth with neuroendocrine differentiation (ND) in the nipple. To our knowledge,<br />

although only five cases of Bowen’s disease have been reported in the nipple, such a unique SCC has<br />

not been reported previously.<br />

[Background]Amyloidosis is one of the protein con<strong>for</strong>mational disorders that normally soluble proteins<br />

accumulate insoluble amyloid fibrils, with the result being severe organ dysfunction. It is documented<br />

that 27 different amyloidogenic proteins. While pathologists identify the amyloid precursor protein by<br />

immunohistochemistry (IHC) using antibodies against known amyloidogenic proteins, the results may<br />

be inconclusive owing to the loss of epitope or small amounts of amyloid deposits, unknown<br />

amyloidogenic protein. In this study, we investigated the usefulness of proteomic analysis <strong>for</strong> amyloid<br />

typing.<br />

[Methods]We used <strong>for</strong>malin-fixed and paraffin-embedded (FFPE) tissue sections <strong>for</strong> identifying<br />

amyloid precursor protein in amyloid-laden specimen using LC-MS/ MS. We attempted retrospective<br />

analysis of 20 amyloid-laden specimens (AL, FAP, SSA AA and DRA) to detect amyloidogenic protein.<br />

There<strong>for</strong>e, we analyzed amyloid precursor protein of 9 amyloid specimens including cases unidentified<br />

by IHC in a prospective study.<br />

[Result] In the retrospective study, we detected amyloidogenic protein from FFPE materials in some<br />

type of amyloid using LC-MS/ MS. The concordance rate with IHC was 95% (19/ 20). There<strong>for</strong>e, in<br />

cases IHC was difficult to determine, we also identified amyloidogenic protein in a prospective study.<br />

[Conclusion] LC-MS/ MS have a potential tool to identify amyloidgenic protein from FFPE tissue. This<br />

method is useful <strong>for</strong> diagnosis of amyloidosis, even cases that are difficult to diagnose by IHC and in<br />

rare cases of amyloidosis.<br />

(Background) The molecular targeting agents that are currently available <strong>for</strong> various malignant<br />

neoplasms. The effects of molecular targeting agents are divided into two subgroups, oncogene<br />

addiction (OA) and non-oncogene addiction (NOA). Bevacizumab, anti-vascular endothelial growth<br />

factor antibody is one of major agents of non-oncogenic addition although the therapy is permitted only<br />

experimentally in Japan. Malignant glioma, especially, glioblastoma (GB), and highly vascularized brain<br />

tumors are thought to be the one of the attractive targets <strong>for</strong> anti-angiogenic therapies. To elucidate<br />

morphological changes of tumor after NOD therapy is important to evaluate the effects of the drug. So<br />

we examined the morphological change of malignant glioma after Bavacizumab therapy using 3 autopsy<br />

cases.<br />

(Materials and Methods) Three cases in men were used. The range of age is from 37 to 64yrs. These 3<br />

cases received Bemacizumab therapy, and radiation therapies were combined. The microscopic slides of<br />

surgical resected and autopsied specimen were compared using HE and immunohistochemistry (IHC)<br />

<strong>for</strong> vascular endothelial growth factor, EGF A and C, vascular endothelial growth factor receptor, Fltand<br />

Flk-1, platelet derived growth factor (PDGF), CD31, CD34, smooth muscle cell actin (SMA) and<br />

aquaporin 1 and 4. And 5 cases of GB are examined <strong>for</strong> control.<br />

(Results) No significant change of morphology of tumor cells is identified after Bevacizumab therapy,<br />

but the morphology of neovasculature is different from conventional GB. A few glomeruloid<br />

appearances and hyperplasia of SMA positive cells are identified. On IHC, the reactivity <strong>for</strong> VEGF A<br />

was decreased but VEGF-C and Flt-1 were preserved.<br />

(Conclusion) The morphological difference between with and without administration of Bemasizumab<br />

in neovasculature suggests decreased expression of VEGF-A.<br />

In Japan, asbestos-related diseases are predicted to increase in number within a few decades probably<br />

due to the retarded political and legal acts <strong>for</strong> protection from the toxicity of asbestos fibers (AF).<br />

Asbestos body (AB) is rarely encountered in the cytology smears particularly of routine specimens even<br />

in the patient presenting asbestos-related respiratory symptoms. In our surgical pathology file, ABs<br />

could be detected in 5 cases out of 1253 cases (0.40%), 2496 specimens in which cytological<br />

examinations were per<strong>for</strong>med in respiratory specimens. The smears included the specimens of sputum,<br />

bronchial brushing, bronchoalveolar lavage (BAL), bronchial aspirate and tissue-imprint. All patients<br />

were 58 to 72 (mean: 67.0) years-old Japanese male. Among the 5 cases, ABs were identified in the<br />

smears of sputum (1/5, 20%), BAL (3/5, 60%), and tissue-imprint (1/5, 20%). A large number of ABs<br />

were found in one case (case #1) who died due to respiratory failure by asbestosis and submit autopsy<br />

(case report presented in the 59 th National Congress of JSLM). Briefly, he had the history of<br />

occupational asbestos-exposure <strong>for</strong> 13 years. Over 100 asbestos bodies were counted in one H&E<br />

sections of the lung in histological examination. Case #2 was histologically diagnosed as<br />

pneumoconiosis after cytological identification of AB in BAL fluid. Case #3 was pulmonary nodular<br />

amyloidosis and AB was incidentally noticed in the BAL smears. In the case #4, BAL was per<strong>for</strong>med<br />

<strong>for</strong> the examination of interstitial pneumonia associated with rheumatoid arthritis, and AB was<br />

cytologically observed in the fluid. In another case #5, AB was found in the tissue-imprint smears of the<br />

lung of VATS specimens resected <strong>for</strong> metastatic tumor from rectal cancer. Tissue specimens were<br />

obtained in the cases #1 and #5 in which analyses of AB and AF will be carried out after extraction from<br />

<strong>for</strong>malin fixed or paraffin embedded tissues.<br />

Aim: We present a case fulfilling diagnostic criteria of chronic inflammatory demyelinating<br />

polyradiculoneuropathy (CIDP) with a progressive course refractory to immunosuppressive therapy, and<br />

showing autopsy findings indicative of amyotrophic lateral sclerosis.<br />

Methods: A clinicopathological case report.<br />

Results: A patient, 62 year-old male, developed motor weakness, muscle atrophy, and sensory deficits in<br />

both upper and lower limbs in a progressive course. On examinations, cerebrospinal fluid showed<br />

protein-cellular dissociation, neurophysiological studies revealed reduced motor and sensory nerve<br />

conduction velocities with prolonged distal latencies in multiple nerves. Biopsy of sural nerve showed<br />

segmental demyelination in teased fibers, fulfilling diagnostic criteria of definite CIDP. Systemic motor<br />

weakness and muscle atrophy progressed after repeated intravenous immunoglobulin infusions and<br />

steroid pulse therapies. Patient died of respiratory failure after the disease duration of 3 years and 5<br />

months. Autopsy revealed diffuse loss of myelinated fibers in anterior and posterior roots. Cellular loss<br />

of posterior root ganglia was observed as well. Sciatic nerve showed demyelination and perineurial<br />

edema. Anterior horn cells were massively reduced and pallor of lateral columns was found along the<br />

whole levels of spinal cord. Iliopsoas muscle and diaphragm exhibited marked neurogenic atrophy.<br />

Some brainstem nuclei showed neuronal loss.<br />

Conclusions: The present case suggests that an association of amyotrophic lateral sclerosis may be a<br />

factor <strong>for</strong><br />

therapeutic refractoriness in some patients with polyneuropathy resembling CIDP. Causal relationship<br />

between demyelinating neuropathy and loss of anterior horn cells is uncertain.<br />

Synthesis of cDNA and Detection of Gene Fragment of Protein Disulfide Isomerase<br />

Family a Member 4 (PDIA4) in Bone Marrow Cell<br />

Stefanus Lembar<br />

Atma Jaya Medical Faculty Indonesia<br />

Background: Protein disulfide isomerase (PDI) is a member of the thioredoxin super-family that<br />

present in the endoplasmic reticulum (ER) in eukaryotic cells. PDI catalyzes of disulfide bond <strong>for</strong>mation,<br />

reduction, or isomerization of newly synthesized proteins in the lumen of the ER. PDI confers resistance<br />

to apoptosis under hypoxic conditions. Hypoxia is physiologically very important in the mechanism of<br />

ER stress. Several clinical studies indicate that tumor hypoxia predicts the decline of local control,<br />

increased distance metastasis, and decreased survival of tumor cells. PDIA4 or also known as ERp72 is<br />

a PDI family member that expressed on bone marrow cells and mammary gland. Low expression of<br />

PDIA4 as a result of ER stress on the condition of hypoxia may play a role in the process of tumor<br />

metastasis. There<strong>for</strong>e, detection and amplification of PDIA4 gene needs to be done to study the<br />

mechanism and changes in sequences of PDIA4 that may contribute to tumor metastasis.<br />

Objective: To synthesize of cDNA and detection of PDIA4 gene fragment in bone marrow cell.<br />

Methods: cDNA was synthesized from bone marrow cell total RNA by RT-PCR using a commercial kit.<br />

Qualitative and quantitative analysis of cDNA per<strong>for</strong>med using the NanoDrop. Detection of PDIA4<br />

gene fragment by cDNA amplification using conventional PCR. PCR products visualized using 1 %<br />

agarose gel electrophoresis.<br />

Results: Quantitative analysis of cDNA showed that the cDNA has a concentration of 383 ng/μL.<br />

Amplification of cDNA with primers F-full mPdia4 and R-full mPdia4 successfully carried out with the<br />

primers concentration of 100 nM and annealing temperature of 50 °C. PCR products were demonstrated<br />

by visualization of DNA bands on agaorse gel electrophoresis with a size of about 1925 bp.<br />

Conclusion: cDNA have been successfully synthesized from bone marrow cell total RNA and amplified.<br />

Furthermore, DNA sequencing will be conducted to verify the suitability of the PDIA4 gene fragment<br />

sequences.<br />

Lynch syndrome, caused by a germline mutation in a mismatch repair gene and associated with tumors<br />

exhibiting microsatellite instability (MSI), is characterized by an increased risk of colon and<br />

extracolonic cancers. Evaluation of MSI through immunohistochemistry of the 4 MMR proteins<br />

followed by molecular genetic testing is necessary <strong>for</strong> accurate diagnosis of Lynch syndrome. We<br />

identified 47 patients with suspected Lynch syndrome <strong>for</strong> whom we aimed to analyze the protein<br />

expression profile of MMR protein, MLH1, MSH2, MSH6 and PMS2 using immunohistochemistry and<br />

to screen <strong>for</strong> germline mutations in MLH1, MSH2, MSH6 and PMS2 gene. MMR protein expression was<br />

immunohistochemically analyzed on paraffin blocks of resected colorectal specimens. DNA extracted<br />

from blood were screened <strong>for</strong> germline mutations in 19 exons of MLH1, 16 exons of MSH2, 10 exons of<br />

MSH6 and 15 exons of PMS2 gene using dHPLC and followed by DNA sequencing. Absent expression<br />

of any MMR protein was observed in 14/47 patients (29.8%). Germline mutation of MLH1 gene was<br />

identified in 2/47 patients (4.2%) consisted of c.1851_1853delGAA (Lys618del) but MLH1 promoter<br />

polymorphism -93G>A was frequently identified (32/47, 68%). Germline mutation in MSH2 gene was<br />

identified in 6/47 patients (12.8%) consisted of a novel mutation, c.2005G>C (Gly669Arg), c.142G>T<br />

(Glu48Stop), c.2701G>A (Glu901Lys) and splice-site mutation, c.2006-6T>C which was adjacent to the<br />

exon 13 of MSH2 gene. Germline mutation of MSH6 was also identified in 1/47 patients consisted of a<br />

novel mutation, c.3885_3891delTAAAAGC (Lys1296MetfsX29) and mutation in PMS2 gene was<br />

identified in 2/47 (4.2%) patients namely c.59G>A (Arg20Gln), c.1408C>T (Pro470Ser), c.1454C>A<br />

(Thr485Lys), c.1621A>G (Lys541Glu) and c.2324A>G (Asp775Ser). Immunohistochemistry proved to<br />

be a good pre-screening tool be<strong>for</strong>e germline mutation analysis of MMR genes. Immunohistochemical<br />

profiling of protein expression and germline mutation screening of MMR genes together are important<br />

in differential diagnosis of Lynch syndrome from familial colorectal cancer.<br />

Background: The essential oils are used <strong>for</strong> aromatherapy classified into alternative medicine.<br />

However, there are few evidences of the action mechanism of essential oil <strong>for</strong> the body. To elucidate<br />

the possibility of the prevention of an allergic disease by the aromatherapy, we investigated the effects<br />

of essential oil using murine asthma model.<br />

Methods: Female BALB/c mice of 8-9 weeks were divided into a control mice (A), an asthma mice (B),<br />

the essential oil (Lavandula angustifolia) treated-asthmatic mice (C) and (D). To make asthma mice, B,<br />

C, and D were sensitized by intraperitoneal injection of Ovalbumin (OVA) at day 0 and 14, and<br />

challenged via airways with OVA on Days 28, 29, 30. After 48 to 72 hours later of last OVA challenge,<br />

airway resistances were assessed. The cell numbers, cytokine levels in BAL fluid, and serum<br />

OVA-specific IgE levels were measured. The mucus-containing cells were counted in periodic<br />

acid-Schiff (PAS) stained sections. For C and D, 5 µl and 20 µl of essential oil were applied <strong>for</strong> 20<br />

min from day 14, 5days of week.<br />

Results: The airway resistance significantly increased in B, C and D. The total cell numbers were<br />

significantly reduced in C and D compared with B. The eosinophil numbers were significantly<br />

reduced in D compared with B. IL-13 levels in BAL fluid were significantly reduced in group D<br />

compared with group B. The serum IgE levels were increased in each group except <strong>for</strong> A. There<br />

were significant reductions of the PAS positive cells in C and D compared with B.<br />

Conclusion: Treatment with Lavender essential oil of asthma mice decreased the number of total cells<br />

and eosinophils, IL-13 levels in BALF, and bronchoalveolar PAS positive cells. These results are<br />

indicating that aromatherapy may have possibility to be used <strong>for</strong> prevention of allergic inflammation,<br />

such as asthma.<br />

Aim: Hypoxia and interactions with bone marrow mesenchymal stromal cells (MSC) have emerged as<br />

essential components of the leukemic microenvironment in promoting leukemia cell survival. High<br />

levels of trans<strong>for</strong>ming growth factor beta 1 (TGF-β1) produced by stromal cells regulate cell<br />

proliferation, survival, and apoptosis, depending on the cellular context. In this study, we investigated<br />

the anti-leukemic effects and molecular mechanisms of action of TGF-β neutralizing antibody 1D11<br />

under hypoxic conditions. We further investigated the anti-leukemic efficacy of 1D11 combined with<br />

CXCR4 antagonist plerixa<strong>for</strong> in the in vivo leukemia models.<br />

Design and Methods: The antileukemic effects and molecular mechanisms of action of monoclonal<br />

pan-TGF-β-neutralizing antibody 1D11 were determined utilizing flow cytometry, western blot, qPCR,<br />

and siRNA technology. The in vivo efficacy of 1D11 combined with CXCR4 antagonist Plerixa<strong>for</strong> was<br />

investigated in the Baf3/ITD model.<br />

Results: RhTGF-b1 induced accumulation of acute myeloid leukemia (AML) cells in a quiescent G0<br />

state under MSC co-culture conditions, which was abrogated by 1D11. TGF-β1 upregulated p21<br />

expression and the TGF-β target leukemia inhibitory factor (LIF) gene in AML cells which in turn<br />

promoted pro-survival phosphorylation of Stat3. 1D11 blocked these effects and enhanced<br />

Ara-C-induced apoptosis of AML cells in hypoxic and in normoxic conditions. Treatment with 1D11<br />

combined with Plerixa<strong>for</strong> and Ara-C decreased leukemia burden in an in vivo leukemia model.<br />

Conclusions: Blockade of TGF-β by 1D11 and abrogation of CXCL12/CXCR4 signaling may enhance<br />

the efficacy of chemotherapy against AML cells in the hypoxic BM microenvironment.<br />

Background: Enterococcus spp. is one of prominent nosocomial pathogens that cause clinical<br />

infections. CDC has reported a remarkable increase in the occurrence of vancomycin-resistant<br />

enterococci (VRE) in hospitals. VRE and SalmonellaEnteritidis (SE) have been reported in poultry<br />

samples and transmission to human. We aim to develop a thermostabilized multiplex PCR, a<br />

DNA-based cold chain free test <strong>for</strong> identification of VRE and SE.<br />

Methods: VRE Multiplex PCR that detects 6 genes simultaneously was developed in previous study.<br />

The Salmonella Enteritidis virulence gene detection was incorporated. Several conditions (e.g.<br />

annealing temperature, premix buffer selection, concentration of Taq polymerase and concentration of<br />

enzyme stabilizer) of PCR were optimized.<br />

Results: In multiplex PCR, optimum annealing temperature of 64.8oC and commercial premix C buffer<br />

<strong>for</strong> PCR reaction were determined. 75% of Taq polymerase and 3% enzyme stabilizer appeared to be<br />

optimum in thermostabilized multiplex PCR.<br />

Conclusion: The DNA based method was successfully optimized. This detection can be used to<br />

facilitate surveillance in poultry and human samples.<br />

Exclusion of Fas gene exon 6 by alternative splicing of the primary RNA transcript of the<br />

apoptosis-inducing Fas gene produces a soluble iso<strong>for</strong>m. The membrane Fas (mFas) iso<strong>for</strong>m induces<br />

apoptosis, while the soluble Fas (sFas) iso<strong>for</strong>m prevents apoptosis. Serum levels of sFas in patients with<br />

some autoimmune diseases and with cancer are higher than healthy individuals, and clinically correlate<br />

with disease activity or tumor mass size. However, the regulatory mechanism <strong>for</strong> Fas gene splicing<br />

remains unknown. Several pre-mRNA splicing regulators <strong>for</strong> Fas gene were reported, but these studies<br />

only targeted extrinsic Fas minigene introduced into cell lines. Here, by quantitative real-time RT-PCR<br />

analysis, we have investigated whether candidates of transcription factors including Hu antigen R<br />

(HuR), T-cell intracellular antigen 1 (TIA-1) and TIA-1 related proteins (TIAR) actually regulate<br />

intrinsic Fas gene splicing in various human organs and lymphocyte subsets. Each gene expression<br />

was different in organs, but there was a poor correlation in gene expression between Fas and<br />

transcription factors. We next analyzed<br />

gene expression by CD45RA+ or CD45RO+ peripheral lymphocytes from healthy donors. Although<br />

sFas and mFas gene expression by these subsets were significantly different, no correlation between<br />

Fas, HuR, and (TIA-1+TIAR) gene expression was obtained. These results suggested that transcription<br />

factors reported should not necessarily function as regulators <strong>for</strong> intrinsic Fas gene splicing.<br />

Objective Congenital Hyperinsulinism (CHI) is a disorder of glucose metabolism by dysregulated<br />

secretion of insulin from pancreatic β-cells. This disease is associated with mutations of ABCC8 and<br />

KCNJ11, which are genes of two subunits of the pancreatic β-cell ATP sensitive potassium channel.<br />

Patients and Methods In 31 Japanese CHI patients, all exons of ABCC8 and KCNJ11 were analyzed by<br />

PCR and direct sequencing. Multiplex Ligation-dependent Probe Amplification (MLPA) was also<br />

applied to analysis of copy numbers in the region of ABCC8.<br />

Results We found mutations in 22 patients out of 31 patients. The 19 patients showed mutations in<br />

ABCC8 and 3 patients showed those in KCNJ11. The mutations of ABCC8 in 19 patients contained 7<br />

nonsense mutations, 8 missense mutations, 3 aberrant-splicing mutations and 1 one base deletion<br />

mutation. These mutations distributed broad in ABCC8, although some missense mutations existed<br />

around two nucleotide-binding domains and membrane domains. The mutations of KCNJ11 in 3<br />

patients contained 2 missense mutations, and each one of one base deletion and two base deletion<br />

mutations. One patient having KCNJ11 mutation was a compound heterozygote of missense and one<br />

base deletion mutations. All of the patients having missense mutations in ABCC8 were heterozygotes<br />

and responsive to diazoxide or octreotide to inhibit insulin secretion except one patient, who needed<br />

operation. All of the patients showing nonsense mutations in ABCC8 underwent a subtotal or partial<br />

pancreatectomy to control blood glucose levels. The homozyotes of ABCC8 mutations or the compound<br />

heterozygotes of KCNJ11 mutations also had operations. Analysis by MLPA showed no abnormal<br />

results of copy numbers in ABCC8.<br />

Conclusion The 23 kinds of mutations reported in this study could be pathological candidates <strong>for</strong> CHI<br />

in Japan. The genetic diagnosis <strong>for</strong> these mutations might be applicable <strong>for</strong> prediction of prognosis and<br />

improvement of management in CHI patients.<br />

BRAF gene mutations have been reported in 30-50% of malignant melanoma patients. Because of the<br />

difficulty of early diagnosis of the disease, poor prognosis was observed in far advanced melanoma<br />

patients. However, recent development of therapeutic intervention using BRAF inhibitors showed<br />

improved prognosis of such patients. There<strong>for</strong>e, an accurate and rapid detection system <strong>for</strong> BRAF<br />

mutations is desired. In addition, the clinical characteristics of the melanoma associated with BRAF<br />

mutations in Japanese patients have not been investigated on a large scale evaluation. We recently<br />

established quenching probe system (QP) <strong>for</strong> detection of an activating BRAF mutation V600E, and<br />

evaluated 113 melanoma samples diagnosed in Saga University Hospital from 1982 to 2011. The QP<br />

system includes fully automated genotyping, based on analysis of the probe DNA melting curve, which<br />

binds the target mutated sites using a fluorescent guanine quenched probe. BRAF mutations were<br />

detected in 54 of 115 (47%) including 51 of V600E and 3 of V600K in Japanese melanoma cases.<br />

Among clinical subtypes of melanoma, nodular melanoma showed high frequency (12 of 15; 80%) of<br />

the mutation followed by superficial spreading melanoma (13 of 26; 50%). Clinical stages and sex<br />

difference were not associated with mutation frequency and mutation sites. The QP system is a simple<br />

and sensitive method to determine BRAF V600E mutation, and will be useful tool <strong>for</strong> patient-oriented<br />

therapy with BRAF inhibitors.<br />

Mycobacterium detection using genetic techniques are rapid tests that are mainly based on nucleic acid<br />

amplification. Many laboratories in Japan use the COBAS TaqMan 48 Analyzer (Roche Diagnostics), a<br />

real-time PCR-based system that uses TaqMan hydrolysis probes. This system is efficient and easy to<br />

use and has good sensitivity and specificity. However, this system can only detect the M. tuberculosis<br />

and M. avium complex among mycobacteria. We examined methods to detect M. kansasii using the<br />

amplicon generated by the COBAS TaqMan 48 Analyzer by real-time PCR using a hydrolysis probe.<br />

We used the type strains of 7 mycobacterial species: M. avium, M. <strong>for</strong>tuitum, M. gastri, M. intracellular,<br />

M. kansasii, M. marinum, and M. tuberculosis. We extracted the total nucleic acids from these type<br />

strains and per<strong>for</strong>med the COBAS TaqMan MTB Test (Roche Diagnostics) or the COBAS TaqMan<br />

MAI Test (Roche Diagnostics) on a COBAS TaqMan 48 Analyzer. After the reaction, the amplicons<br />

were cleaned using the High Pure PCR Product Purification Kit (Roche Diagnostics). The M. kansasii<br />

detection primer pair was designed from the inner sequence of 16S rRNA, which was used in the<br />

COBAS TaqMan 48 Analyzer. The detection probe used was highly specific <strong>for</strong> M. kansasii, and the<br />

locked nucleic acids were incorporated into the probe to increase specificity. Real-time PCR was<br />

per<strong>for</strong>med using Light Cycler 1.5 (Roche Diagnostics).The primer and probe <strong>for</strong> M. kansasii detection<br />

accepted the amplification of M. kansasii and M. gastri. M. kansasii lung disease shows the highest<br />

response to chemotherapy, and the method <strong>for</strong> its treatment is better established than that <strong>for</strong> other<br />

non-tuberculous mycobacterial infectious diseases. Since early and rapid detection of M. kansasii is<br />

very important, we suggested that our method can be employed to detect M. kansasii using COBAS<br />

TaqMan 48 Analyzer in routine laboratory work.<br />

Increased expression of mitochondrial isoenzyme of creatine kinase in<br />

hepatocellular carcinoma cells may be associated with enhanced proliferation and<br />

migration<br />

Uranbileg B., Ikeda H., Yatomi Y.<br />

Project researcher, Department of Clinical Laboratory Medicine, Graduate School of Medicine, The<br />

University of Tokyo, Japan<br />

Mitochondrial isoenzyme of creatine kinase (MtCK) has been postulated to be important <strong>for</strong> the<br />

energetics of oxidative tissues, suggesting that MtCK might play crucial role(s) in malignant<br />

trans<strong>for</strong>mation.<br />

We have recently reported the increased serum MtCK activity in patients with hepatocellular carcinoma<br />

(HCC), and suggested that MtCK could be a novel serum marker <strong>for</strong> HCC. Although we revealed the<br />

increased MtCK mRNA expression in HCC cell lines as one of its mechanisms, its significance has been<br />

largely unknown.<br />

The reduction of MtCK expression in HCC cell lines, i.e., HepG2, Alex and HuH7, by siRNA led to the<br />

decrease in cell proliferation by 31.7% in HuH7, 19.8% in HepG2, and 15.5% in Alex measured by<br />

BrdU incorporation assay. Furthermore, the reduction of MtCK expression in HepG2, Alex, HuH7<br />

caused the decrease in cell migration, maximum by 85.2% in HuH7, and cell invasiveness also reduced<br />

in all three cell lines, maximally detected in HuH7 by 92.3% which was determined by cell migration<br />

and invasion assay.<br />

Because ASB9 (Ankyrin repeat and suppressor of cytokine signaling box protein 9) was previously<br />

reported as a potential regulator of MtCK expression, its expression level in HCC cell lines was<br />

investigated. It was found that ASB9 mRNA expression in all HCC cell lines examined was much lower<br />

than that in normal liver tissue. This negative correlation between the expressions of MtCK and ASB9 in<br />

HCC cell lines may suggest that ASB9 could be a negative regulator <strong>for</strong> MtCK expression in HCC.<br />

In conclusion, the increased expression of MtCK in HCC cell lines may be associated with the enhanced<br />

proliferation, migration and invasion, which consistent with MtCK is being a serum marker <strong>for</strong> HCC.<br />

MtCK and its negative regulator, ASB9, merits consideration as a therapeutic target <strong>for</strong> HCC.<br />

Application <strong>for</strong> Diagnostic Tests of Facial Portraits by CCD Camera<br />

Kazuhiro Kabe<br />

Business Department of Medical Technology, Laboratory of Medical Technology<br />

Medic21 Association, Japan<br />

Aim : At daily clinical diagnostic tests, as it is very important to judge whose each specimen it is, we<br />

can think that it is good to photograph faces in order to discriminate individuals of test subjects. I<br />

investigated the changes by making facial portraits by a CCD Camera, by discriminating individuals and<br />

by including simple photographing systems in personal-computers to determine whether individual<br />

discrimination of judged specimens succeeds to be practicable.<br />

Materials and Methods : I per<strong>for</strong>med by joining CCD Camera with personal-computers, through<br />

softwares to take in portraits, by adjusting shades of portraits to signals, by dividing into two kinds, by<br />

letting indicate that shadowy directions were “1” and light directions were “0”, by <strong>for</strong>ming a line of both<br />

0 and 1 and by including systems that let express facial portraits by both 0 and 1 in personal-computers.<br />

Results : As a result of expressing man’s facial portraits by shades of both 0 and 1, man’s facial portraits<br />

<strong>for</strong>med a line of shades of both 0 and 1 and at both the same man and position, in comparing the first<br />

time with the second time, coincided almost closely. But when the photographing position changed,<br />

somewhat slipped out rows of both 0 and 1. And when the man also changed, somewhat slipped out<br />

rows of that.<br />

Conclusions : By using CCD Camera, individual discrimination by facial portraits seems to be well<br />

practicable. There<strong>for</strong>e, by also using cellular phones, individual discrimination seems to be well<br />

practicable. At clinical diagnostic tests, if we introduce these CCD cameras, individual discrimination of<br />

specimens seems to be effectively practicable by using that of this facial portrait.<br />

1 Central Clinical Laboratory, Nara Medical University, 2 Center <strong>for</strong> <strong>Education</strong> Development, Nara<br />

Medical University, Japan<br />

Aim: Cardiac side effect of anthracycline limits its potential utility. Recent studies have reported that<br />

latent anthracycline-induced cardiomyopathy already exists even in patients with preserved left<br />

ventricular (LV) ejection fraction (EF). We investigated LV mechanical dyssynchrony in<br />

anthracycline-induced cardiomyopathy with preserved LVEF.<br />

Methods: We studied <strong>for</strong>ty-seven patients with non-Hodgkin’s lymphoma who were previously treated<br />

with anthracycline repeatedly. All patients had no history of cardiac disease and showed preserved<br />

LVEF (≥ 60%). Myocardial strain rate obtained with speckle tracking was used to assess ventricular<br />

synchrony. Time to regional peak strain rate was measured in 12 LV segments from the apical 4- and 2-<br />

chamber views and standard deviation (SD) in all 12 segments was measured as an estimate of LV<br />

dyssynchrony. Also the relationship between SD and LVEF was assessed. Thirty-eight healthy<br />

volunteers served as controls.<br />

Results: Although LVEF was preserved in all patients, it was significantly decreased compared with<br />

controls. SD of time to peak strain rate was significantly greater in patients than controls. SD was<br />

negatively correlated with LVEF in patients.<br />

Conclusion: This study suggests that LV mechanical dyssynchrony exists and causes latent LV<br />

dysfunction in patients with anthracycline-induced cardiomyopathy with preserved LVEF.<br />

Influence of masticatory dysfunction on antioxidant capacity in rat model<br />

Maki Tanaka, Kageaki Kuribayashi, Daisuke Kobayashi, Naoki Watanabe<br />

Department of Clinical Laboratory Medicine, Sapporo Medical University School of Medicine, Japan<br />

Mastication is an essential function to maintain homeostasis of the animal. Disturbance in mastication<br />

induces physical and psychological stresses. It has been elucidated that level of free radical, such as<br />

superoxide, increases following physical and psychological stresses leading to various disorders,<br />

including cancer and gastrointestinal ulcer. In this study, we investigated whether masticatory<br />

dysfunction causes oxidative stress by changing feeding style from solid to liquid meal in rat model.<br />

Neutrophils were collected from rats fed with solid or liquid meal, respectively, and superoxide<br />

production was measured by cytochrome c reduction method. Serum superoxide dismutase activity was<br />

evaluated using electron spin resonance spin-trapping technique. As a result, level of superoxide<br />

production was higher in rats fed with liquid than solid meal. Furthermore, serum superoxide dismutase<br />

(SOD) activity was lower in the <strong>for</strong>mer group. Decrease in serum SOD activity sustained from day 21 to<br />

day 84 after meal was changed from solid to liquid meal. In rats fed with liquid meal, serum SOD<br />

activity recovered to normal level 7 days after liquid meal was reversed to solid meal. These results<br />

show that oxidative stress continues when mastication is disturbed. This study suggests that chewing<br />

harmless solid materials, such as gum, may help avoiding unnecessary oxidative stress in patients<br />

treated with liquid nutrition.<br />

Objectives: Further characterization of the interaction between Rb3/p130 and PP2A upon All-trans<br />

retinoic acid (ATRA) treatment as it has been shown to arrest the growth of the CAOV3 ovarian<br />

carcinoma cells in the GO/G1 phase and to elevate levels of Rb2/p130 protein, a member of the<br />

retinoblastoma family of tumor suppressors. Materials and Methods: CAOV3, was obtained from<br />

theAmerican Culture Collection (Rock-ville, MD), Anti-PP2Ac, Anti-Rb2/p130, Antiactin, Anti-His<br />

antibodies were purchased from Santa Cruz Biotechnology (CA), The phosphatase inhibitor okadaic<br />

acid (OA) was purchased from Sigma Life Sciences (Atlanta, GA). Endothall, a specific PP2A inhibitor,<br />

was purchased from Calbiochem (La Jolla, CA). ATRA was obtained from Hoffman La Roche (Nutley,<br />

NJ). Western blotting and immunoprecipitation, Phosphatase assay, Cloning and truncation,<br />

Muta-genesis, Generation of CAOV3 cells were per<strong>for</strong>med as described by Soprano DR et all. 2006).<br />

Results: ATRA treatment leads to hypophosphorylation of PP2Ac, which correlates with increased<br />

PP2A, a serine/threonine phosphate, and binds and dephosphorylates Rb2/p130 in the cell. We observed<br />

that the N-terminus of PP2A catalytic subunit (PP2Ac) interacts with nuclear localization signals (NLS)<br />

in the C-terminus of Rb2/p130. PP2Ac methylation is also increased following ATRA treatment and<br />

PP2A methylating-enzyme (PMT) transcript levels are elevated as early as 6 hrs following ATRA<br />

treatment. Immunoprecipitation studies reveal that PP2A and Rb2/p130 interact with importin β and<br />

importin α, members of the nuclear transport machinery. Importin α recognizes a nuclear localization<br />

signal (NLS) on a target protein and importin β binds the nuclear pore complex. CAOV3 cells<br />

transfected with a truncated C-terminus region of Rb2/p130 in which the NLSs were mutated, no<br />

interaction with PP2A was observed and these cells were as sensitive to ATRA treatment as parental<br />

CAOV3 cells. This suggests that Rb2/p130 interaction with PP2A is required <strong>for</strong> the induction of cell<br />

cycle arrest in ATRA treated cells. Conclusions: The results suggest that ATRA treatment leads to a<br />

variety of responses that promote cell cycle arrest in ATRA sensitive COAV3 cells, including the<br />

activation of a key phosphatase, PP2A, which enhances the stability and nuclear location of a tumor<br />

suppressor protein, Rb2/p130.<br />

Material and methods: A total of 1,555 unrelated individuals of Khalkh-Mongolian origin from the<br />

region of Ulaanbaatar, Mongolia participated in the study. Four DNA pools were prepared. The first set<br />

was DNA pools of 125 male-tall, 125 male-short, 125 female-tall, and 125 female-short samples. A<br />

second set was also grouped from another 125 male- and female-tall samples and 125 male- and<br />

female-short samples. All microsatellite markers and methods <strong>for</strong> microsatellite genotyping used in this<br />

study are described by Tamiya et al. (2005).<br />

Results: We per<strong>for</strong>med a genome-wide association study with 23,465 microsatellite markers <strong>for</strong><br />

detection of loci controlling adult height using the selective genotyping method. To reduce cost and<br />

technical burden of genome-wide genotyping, the pooled DNA method was applied. Association results<br />

with the pooled DNA method and following re-genotyping of individual DNAs using the same set of<br />

1,000 screened individuals, 23 markers showed significant differences by Fisher’s exact test. These<br />

markers were subjected to correction of multiple tests with the number of alleles, and nine<br />

microsatellites remained significant. We detected significant association in chromosomes 3, 4, 8, 15,<br />

and 17. In addition, five regions overlapped at least partially with loci previously reported by linkage<br />

analysis (5q31, 6q25, 8q21.3, 8q21.13, and 21q21.1). We also detected six strongly associated regions,<br />

4q13.2, 4q31.3, 5q21.3, 7p21.1, 7q11.22, and 19q13.2, which have not been reported be<strong>for</strong>e. Among the<br />

nine most associated markers, we selected two: D8S0285i and D15S988, the most strongly associated<br />

microsatellite, located at 8q21.13, and D15S988 was flanked by a candidate gene, SMAD3, located at<br />

15q22.33. 82 SNPs were surveyed and genotyped in a total of 1,555 samples (1,000 screened samples<br />

and additional 555 samples).<br />

Conclusions: We have identified two candidate loci <strong>for</strong> adult height at 8q21.13 and 15q22.33-q23 in<br />

Mongolians. Analysis of the remaining seven highly associated microsatellite markers should lead to<br />

identification of new causative genes underlying adult height variation.<br />

Objectives: To investigate the allelic frequencies of HLA class 1 and class II genes in ethnic minority<br />

of Khoton-Mongolians. Materials and Methods: The population studied consisted of 85 randomly<br />

selected healthy Khoton-Mongolians living in the area of Tarialan sum, of Uvs aimag, Mongolia.<br />

Results were compared with control population consisting of 41 randomly chosen healthy unrelated<br />

Khalkh-Mongolians from Ulaanbaatar, Mongolia. Allelic polymorphism in HLA-A, and HLA-B genes<br />

were investigated by the PCR-SSOP method. HLA class II genotyping <strong>for</strong> DRB1, DRB3, DRB5, DQA1,<br />

DQB1 and DPA1 genes were per<strong>for</strong>med by the PCR-SSOP method. The PCR-RFLP method was used<br />

<strong>for</strong> HLA-DPB1 genotyping. Results: Mongolia is a central Asian country with a population of 2.7<br />

million. According to the ethnological studies, over 20 ethnic groups inhabit in the territory of Mongolia.<br />

Among these, the Khalkh population is the largest majority (80% of total). In contrast, the Khoton is a<br />

very small, isolated ethnic group residing in the Uvs aimag, in northwestern Mongolia. The Khoton<br />

population is of special interest because there is no consensus regarding their origin. They are Muslim<br />

people and have mixed very little with other ethnic groups. We investigated the polymorphism of 2<br />

HLA class 1 and 7 HLA class II loci in Khoton-Mongolians in comparison with Khalkh-Mongolian<br />

controls. Combined analysis of HLA class I and class II alleles showed that the two Mongolian<br />

populations examined have significant differences in their distribution of HLA alleles; significantly<br />

higher frequency of HLA-B38, DQA1*0201, DQB1*0201, DPB1*0401 and significantly lower<br />

frequency of HLA-A2, A33, DRB1*1102, DQA1*0103, DQB1*0603, DPB1*0201 and DPB1*1701<br />

were found in minor population of Khoton-Mongolians as compared to major Khalkh-Mongolians.<br />

Several haplotypes were found to be unique to Khoton-Mongolians, such as HLA-A30-B58, A29-B35,<br />

Objectives: Genes of TNF-α (cachectin) and TNF-β (lymphotoxin) are located between HLA-B and<br />

HLA class III, and no allelic polymorphism has been determined in the region of TNF-α loci, where two<br />

alleles TNF-β1 and TNF-β2 has been described, that can inherits in three <strong>for</strong>ms and no gene<br />

frequencies and disease associations yet been fully studied.<br />

Materials and methods: Ncol enzyme based RFLP allelic frequency of TNF-β (lymphotoxin) gene<br />

analysis was per<strong>for</strong>med in 126 healthy Mongolians (85 Khoton , and 41 Khalkh ethnic groups) and 135<br />

Japanese lung cancer patients studied in comparison to 165 normal healthy control subjects.<br />

Results: Gene frequency of 5.5/5.5-kb allele revealed in 12.2% of Khalkh population, and this is much<br />

more frequent in comparison to Khoton population, in whom it was revealed only in 3.5%. But TNF-β<br />

10.5/10.5-kb allele was determined in 49 cases (57.4%) in Khoton population, that was very high in<br />

frequencies in comparison to both Khalkh and Japanese healthy group (34.1% and 41.1%),<br />

(p=0.013440). In the lung cancer patients, the TNF-β 10.5/10.5-kb allele was found at a low frequency,<br />

38.5%, compared to 53.3% in normal controls (chi 2 = 7.51, P = 0.011, corrected P = 0.033, relative risk<br />

= 0.77). In the relationship between the histologic types and the TNF beta 10.5/10.5-kb allele showed<br />

low frequencies: 38.5% in adenocarcinoma, 38.2% in squamous cell carcinoma, and 27.8% in small cell<br />

carcinoma, although no statistical difference was shown. In relation to the postoperative survival period,<br />

the TNF beta 10.5/10.5-kb allele was associated with prolonged survival.<br />

CONCLUSIONS: The TNF beta 10.5/10.5-kb allele may be associated with resistance to lung cancer<br />

and with a better prognosis.<br />

Objectives: The purpose of the present study is to elucidate genealogical and clinical features of<br />

hereditary neuropathy in the several large kindreds of Gobi-Altai province, Mongolia.<br />

Materials and methods: In the present study, we had selected five kindreds originated from Bayan-Uul<br />

sum, Gobi-Altai province. Each participant was enrolled <strong>for</strong> genealogical and neurological examinations<br />

according to the prepared questionnaire. We also have collected biological samples <strong>for</strong> further genetic<br />

study. Genomic DNA was isolated from biological samples, and quantitative analysis of DNA was<br />

determined by spectrophotometer and picogreen assays.<br />

Results: Genealogical analysis revealed that there was linkage between two kindreds in the total<br />

families enrolled into study, whereas no association was revealed among the other pedigrees. As an<br />

external appearance of susceptibility gene or genomic regions of the hereditary neuropathy, the clinical<br />

signs were inheritant in every generation, and the inheritance was not dependent on sample of gender. In<br />

neurological examination, start age of hereditary neuropathy onset was <strong>for</strong> the first decade of life in 4<br />

patients, <strong>for</strong> the second decade of life in 5 patients, and <strong>for</strong> the other members start in the age of over<br />

than 20 years. Common clinical features of hereditary neuropathy were characterized by hypomimicand<br />

mask shape face, muscular atrophy of upper and lower limbs, and pes cavus. Five female patients<br />

were revealed with similar gynecological problems, which was a very interesting case.<br />

Conclusion:<br />

1. The hereditary neuropathy that occurred in the large kindreds of Bayan-Uul sum, Gobi-Altai province,<br />

and the type of inheritance could be categorized as autosomal dominant.<br />

2. Onset of hereditary neuropathy disease started mostly in the second decade of life. Common clinical<br />

features of hereditary neuropathy were characterized by hypomimic and mask shape face, muscular<br />

atrophy of upper and lower limbs, and pes cavus. Apart from general clinical features, the specific<br />

Encapsulating peritoneal sclerosis (EPS) is a serious complication of peritoneal dialysis (PD). A risk<br />

of EPS increases with a development of peritoneal dysfunction where increased peritoneal permeability<br />

is associated with exfoliation and loss of peritoneal mesothelial cells.<br />

In this study, we investigated whether the number and morphology of mesothelial cells in peritoneal<br />

dialysis effluent (PDE) reflect a peritoneal function, and predict increased susceptibility to EPS.<br />

Materials and Methods: PDE samples were obtained from 33 PD patients (26 men, 7 women, PD<br />

duration; 29.1 ± 27.4 months) with peritoneal equilibration test (PET) per<strong>for</strong>med. The number of<br />

mesothelial cells was counted in 36 mm 2 area of slide preparation. According to the classification of cell<br />

morphology based on the life-cycle of mesothelial cells, mesothelial cells were classified into quiescent,<br />

activated, phagocytic, and degenerating cells with the digital microscopy system CellaVision DM96.<br />

PET was used to categorize patients into four transporter groups; high (H), high average (HA), low<br />

average (LA), and low (L).<br />

Results: The number of mesothelial cells in PDE samples was significantly lower in H transporter<br />

group than HA (p < 0.05). Mean numbers of mesothelial cells were 2.7 ± 0.6 <strong>for</strong> H transporter group<br />

(n=3), 15.8 ± 11.4 <strong>for</strong> HA (n = 16), and 14.8 ± 21.7 <strong>for</strong> LA (n = 11), and 11.3 ± 12.9 <strong>for</strong> L (n=3),<br />

respectively. In morphological analysis, whereas both quiescent- and activated- mesothelial cells were<br />

present in HA, LA, and L transporter groups, in H transporter group, however, quiescent cell type was<br />

predominantly observed.<br />

Conclusions: Decreased number of mesothelial cells in PDE of a high transporter membrane state,<br />

suggesting the loss of peritoneal mesothelial cells during chronic peritoneal injury, might be a<br />

convenient and useful predictive marker <strong>for</strong> advanced peritoneal dysfunction.<br />

Background/Purpose: The phenotypic classification of T cells is useful in studies of immunological<br />

diseases. Human CD4+ T cells can be classified as either naive, central memory (TCM), or effector<br />

memory (TEM) cells using CCR7 and CD45RA. We recently discriminated CD4+ T cells into five major<br />

subsets using four markers, CD45RA, CCR7, CD27, and CD28, and defined the function of each<br />

population based on its ability to produce IFN-γ, IL-4, and IL-2. To identify the CD4+ T cell subsets<br />

most important in the pathogenesis of rheumatoid arthritis (RA), we phenotypically defined human<br />

CD4+ T cells as functionally distinct subsets, and analyzed the distribution and characteristics of each<br />

subset in the peripheral blood.<br />

Methods: Peripheral blood mononuclear cells from RA patients and healthy subjects were classified<br />

into different subsets based on the expression of CD45RA, CCR7, CD27, and CD28 using five-color<br />

flow cytometry. The frequency of IFN-γ-, IL-17-, or TNF-α-producing cells, and of Foxp3- or<br />

RANKL-positive cells in each subset was analyzed by eight-color flow cytometry.<br />

Results:<br />

We classified human CD4+ T cells into six novel subsets based on four cell surface markers, CD45RA,<br />

CCR7, CD27, and CD28. We demonstrated that the CD27+CD28+ TCM subset comprised a significantly<br />

smaller proportion of CD4+ T cells in RA patients compared to healthy controls, and within this subset,<br />

the proportion of Foxp3-positive cells was lower. In contrast, the proportion of IL-17- and<br />

TNF-α-producing cells in the CD27+CD28+ TEM subset was significantly increased in RA patients.<br />

Conclusion:<br />

These findings suggest that the total number and/or proportion of inflammatory cytokine- or<br />

Foxp3-positive cells of particular CD4+ T cells subsets is significantly changed in RA patients. These<br />

subsets may provide novel therapeutic targets <strong>for</strong> this disease.<br />

We present a novel technique using incorporation of 5-ethynyl-2′-deoxyuridine (EdU) into replicating<br />

DNA is reported <strong>for</strong> analysis of the replicating banding patterns of human metaphase chromosomes.<br />

Human lymphocytes were synchronized with excess thymidine, and then treated with EdU during the<br />

late S phase of the cell cycle. EdU-incorporated DNA was detected in metaphase chromosomes using<br />

Alexa Fluor ® 488 azides, through the 1,3-dipolar cycloaddition reaction of organic azides with the<br />

terminal acetylene group of EdU. Chromosomes with incorporated EdU during the late S phase showed<br />

a banding pattern that was similar to the G-banding pattern of normal human chromosomes. Atomic<br />

<strong>for</strong>ce microscopic (AFM) images under liquid conditions showed that the structure of the chromosomes<br />

was well preserved even after EdU treatment. Comparisons between fluorescence microscopic images<br />

and AFM images of the same chromosome 1 indicated the presence of ridges and grooves in the<br />

chromatid arm, which corresponded to G-positive and G-negative bands, respectively. These results<br />

suggest an intimate relationship between the EdU-induced replication bands and the G-bands in human<br />

chromosomes. This technique combined with AFM is useful <strong>for</strong> analyzing the structure of chromosomes<br />

in relation to their replication banding pattern.<br />

Background: Chaotic nature of myocardial ultrasonic radio-frequency (RF) signals have been reflected<br />

myocardial tissue properties. However, it is unclear whether the ultrasonic RF signals reflect cardiac<br />

fibrosis in patients with hypertension. Methods: We evaluated 33 patients with untreated hypertension,<br />

randomly assigned to calcium-channel blockers or Angiotensin II receptor blockers <strong>for</strong> 12 months. RF<br />

signals were obtained from the myocardium by the transthoracic echocardiography. We assessed the<br />

correlation dimension (CD) in left ventricular posterior wall at end diastole be<strong>for</strong>e and after treatment.<br />

Plasma adiponectin, matrix metalloproteinase type 1(MMP-1), tissue inhibitor of metalloproteinase type<br />

1 (TIMP-1) and aldosterone were determined with ELISA as cardiac fibrotic markers be<strong>for</strong>e and after<br />

treatment. Results: CD, serum adiponectin, MMP-1 and TIMP-1 did not change after treatment. While,<br />

serum aldosterone decreased after treatment (10.0 (5.5) vs. 13.3 (6.3) ng/dl, p

In human giardiasis, remaining diarrhea after chemotherapy is not rare, due to low compliance with the<br />

therapy, repeated infections or parasite resistance to administrated drugs. Actually, in some clinical<br />

reports, the emergence of drug resistance have been suggested as a cause of treatment failure in<br />

giardiasis, however, the method <strong>for</strong> the drug susceptibility test of Giardia intestinalis and the higher<br />

success rate of isolation method is not yet optimized. In contrast to the field of bacteriology, such as<br />

methicillin-resistant Staphylococcus aureus (MRSA) and penicillin-resistant Streptococcus pneumoniae<br />

(PRSP) etc. Considering these difficult conditions of giardiasis, we have taken a challenge to establish<br />

the metronidazole susceptibility test <strong>for</strong> G. intestinalis. Culture isolation to the axenic condition using<br />

modified YI-S medium (consisting of a nutrient broth, vitamin mixture and serum) of G. intestinalis<br />

was conducted using cysts excreted in patient feces, and 4 out of 6 strains were successfully isolated.<br />

The determination of Giardia genotype was used with molecular biological analysis. Using the<br />

well-grown clinical 3 strains (Su2: assemblage B, Su3: assemblage A, Su4: assemblage A) along with<br />

reference strain Portland-I (PO-1: assemblage A), the metronidazole susceptibility was assessed with a<br />

bioluminescent WST-1 cell proliferation assay (Takara: Japan). The IC50 values of PO-1 and clinical 3<br />

isolates (Su2, Su3, Su4) were 9.36 and 9.45, 6.58, 11.72 (μM) respectively <strong>for</strong> metronidazole. Our<br />

method could isolate both assemblage A and B, common genotypes detection from humans, and the<br />

WST-1 reagent could confirm the drug susceptibility in the culture condition. However, some genotypes<br />

of Giadia have been considered to be difficult to adopt axenic culture condition. So, the best culture<br />

conditions hold the key to the assessment of the drug susceptibility <strong>for</strong> Giardia. In fact, effective drug<br />

choices according to the results of drug susceptibility tests are general protocol in bacterial diseases, and<br />

such a useful assessment method is now available even <strong>for</strong> giardiasis. This study might help to explain<br />

the diversity in drug susceptibility <strong>for</strong> Giardia.<br />
