mWCnts on OVA-asthma model were analyzed by airway hyperreactivity (AHr) measurement, bronchoalveolar lavage fluid (BAlF)
analysis, intracellular rOs production and histological analysis in lung tissue.
Results: intranasally administrated-mWCnts easily loaded in alveolar macrophage, but did not result in significant lung
inflammation and intracellular rOs production of the OVA-induced asthma model. in histological analysis, mWCnts exacerbated
collagen deposition within the lung parenchyma of naïve mice and pre-existing allergic mice.
Conclusion: these results suggest that combined OVA sensitization and mWCnts administration did not affected pre-existing
allergic, but increased collagen deposition in lung parenchyma.

Aim and Methodology: the pollen counts in georgia were studied in 2006-2009 using the vacuum Burkhard Pollen trap (great
Britain) donated by the World Allergy Organization (WAO) to the national institute of Allergology, Asthma and Clinical immunology
in tskhaltubo (georgia). the dependence of allergic diseases prevalence on the geographic location and some other factors (air
temperature, humidity, height above the sea level, spectrum of regional plants) were also studied.
Results: it was stated that allergy to mold fungi and other bacteria more often occurred in the areas with high humidity and the
morbidity level with hay fever and bronchial asthma was much higher than in dry areas. in cities situated on the Black sea (Batumi,
Kobuleti, Poti), ragweed is widely distributed, which in the period of blossom caused numerous allergic diseases (allergic rhinitis,
conjunctivitis, urticaria etc.). When ragweed blossom, the quantity of pollen in the air is extremely high and as it is a strong allergen
it causes exacerbation and allergic disease in people sensitized to ragweed pollen. the highest percentage of allergy morbidity
fall at plants allergens caused by pollen of numerous weeds and plants (pollen of ragweed, alder, birch, maple, walnut, mallow,
cotton-plant etc.). in different areas of georgia people are more sensitive to various plants. in imeretia region, it is ragweed pollen,
in Kakhetia and Kartli – platan and wheat. graphic chart of hay fever and bronchial asthma morbidity as a rule have two peaks –
spring–summer and autumn–winter. it is the season of plants blossom and the quantity of pollen in the air is most high.
Conclusion: the pollen counts obtained using the Burkhard Pollen trap allowed us to make a pollen calendar for different regions
of georgia thus enabling to perform treatment and prophylactic measures in advance.

the air surrounding us plays an extremely important role in our well being and efficiency. Breathing pure and clean air allows us to
think more clearly, sleep more soundly, and stay healthier. studies show that we receive 56% of our energy from the air we breathe,
more than from water and food combined. On average we breathe 37 pounds of air a day. the quality of the environment within
buildings is a topic of major importance for public health and indoor Air Quality (iAQ) is a major concern at work places. the objective
of the present study was to assess two negative ion purifiers - Xtreme 3000 and luna induct air purifiers on the net reduction of
bacteria in the microbiology and mycology laboratories of Baptist saint Anthony’s Hospital (BsA) in Amarillo, texas and the specific
effect on methicillin resistant Staphylococcus aureus, mrsA. mrsA has become a serious public health issue. luna induct air units use
an advanced hydrated Photo-Catalytic Oxidation (PCO) filtration system. it produces a broad spectrum high intensity UV light targeted
on a quad metallic catalyst in a low-level ozone and moist atmosphere. Bacteria isolated from petri plates exposed to the room air
were gram positive bacilli such as Bacillus, Coryneform (diptheroids), coagulase negative Staphylococcus and Micrococcus spp., and
encapsulated gram negative bacilli. in every case there was reduction in airborne pathogen with variable room sizes when the air
purifiers were used. tsA plates with 5% sheep blood were placed for exposure rooms at different distances and intervals. Plates were
evaluated for the total number of bacterial and fungal colonies at intervals of 24, 48, 72 and 120 hours. We plated the mrsA strains
from the stock culture after dilution 10-4 to investigate the effect of air-purifiers on the production of number of colonies of mrsA. tsA
plates were inoculated with the strain after serial dilutions as follows. 5 ml of stock culture was diluted to 10-4 after incubation at 37o C for 24 hours and were plated onto tsA petri plates. ‘t-test’ results show that there was a significant difference in the air purifier
treated sets and a gradual reduction in the number of colonies. the reduction of latent bacteria in the air could possibly reduce the
transmission of airborne disease.
