The aphids were present along the entire cotton crop, but the highest
populations were observed at the emergence of the first square
at the end of effective flowering. In this stage the efficiency and
residual of different foliar insecticides were evaluated in controlling
the Aphis gossypii in cotton crops. The trials were conducted
during the agricultural season 2002-03 and 2003-04 in the experimental
field of La Maria (EEA Santiago del Estero). The design
was block at random with 4 repetitions and the following active
principles: Thiametoxan GW 25, oxidemeton metil CE. 25,
oxidemeton metil CE. 25, Clorpirifos CE.48, Dimetoato CE 50 and
untreated control. Four samplings was determined one previous to
the applications and the rest to two, seven and twenty days later to
applications. The counts of the aphids by leaf were in made in the
fifth leaf of the main stem situated from the apex. The treatments
began with an average density of 40-120 aphids/leaf with a uniform
distribution in the test area.The results show to a significant
difference between the untreated control and the different evaluated
active principles. The Thiometoxam and metil Oxidemeton
applied to the foliage significantly reduce to the population of aphids
in the crop until the twenty days later to the treatments, providing
levels of control over 70%.

Bacterial vaginosis (BV) is one of the most frequent reasons of
consultation by fertile and pregnant women. The normally lactobacilli
are replaced by a polymicrobial flora with abundant short
and curved bacilli, usually Gram-negative or variable (Gardnerella,
Mobiluncus and anaerobic morphology). One hundred sexually
active women, aged between 15 and 66 and treated at the Maternity
in Tucumán, Argentina, were examined (35 of them were pregnant).
From each patient samples were taken (cervix), carrying out
a microscopy study. Gram staining was applied to study bacterial
morphology using the Nugent scale, based on a semi-quantitative
microscopy analysis of the vaginal flora, and Giemsa staining and
a PAP test. In 96% of the cases fewer than 7 PMN per microscopic
field were observed. Prevalence of BV was 23% and an intermediate
stage was observed in 37%. 30% of the women under study
were between 21 and 30 years of age, 26% between 31 and 40,
22% between 41 and 50 and 22% under 20, 37% of the patients
manifesting the disease were pregnant. Analyzing associations with
BV Trichomonas vaginalis was found in 17% and yeast in 9%.
Only in 2 pregnant patients without BV coilocyte and virocyte type
cells were detected. The typical microscopy findings allow differentiation
between normal and infectious secretions. Detection of
coilocytes and virocytes is important, because they predict the presence
of Papilloma virus.

Introduction: The overweight in children and adolescents is associated
to metabolic alterations known as metabolic syndrome (MS).
It is related to a significant increase of diabetes type 2 (DT2) and
cardiovascular disease (CVD) risk.
Objective: to determine risk factors (RF) for MS in children and
adolescents in scholar population.
Materials and methods: 157 students aged 11-16 yr were evaluated.
Parameters of weight (W), height (H), waist circumference
(WC), Blood Pressure (BP) and Body Mass Index (BMI) were determined
in all subjects. After known the presence of one or more
RF, the study was completed with the biochemical analyses and
the nutritional survey.
Results: from the 157 evaluated students, 25,5% have one or more
RF for MS. 17,8% have overweight, 5,7% obesity, 10,2% with WC
>90 percentile, 5,1% with high BP, and 3,2% have lipids profile
alterations. One student presents Glucose greater than 110 mg/dl
(0,6%), and 7 students have high HOMA Index (4,5%). This indicates
Insulin Resistance Syndrome. From the 14 subjects tested in
the laboratory, 7 present 3 or more RF for MS (4,5%).
Conclusions: we suggest the importance of the valuation in children
and adolescents of the RF that constitute the MS to prevent
the complications like DT2 and CVD.

TAXONOMIC STATUS OF JENYNSIA CF. ALTERNIMACULATA
(CYPRINODONTIFORMES: ANABLEPIDAE) FROM THE RÍO
ARENALES BASIN, SALTA, ARGENTINA

The family Anablepidae is composed by 3 genera. Among them,
Jenynsia, is the most diverse. Ghedotti (1998) analyze the phylogenetic
relation-ships of the family. In Salta, Argentina, two species
of Jenynsia are present, J. maculata and J. alternimaculata.
The latter is very similar to the specimens found in Río Arenales.
As the type locality of Jenynsia alternimaculata is in the Río
Bermejo Basin and the Río Arenales do not belong to it, the taxonomic
status of the specimens of the latter river is tested in this
work. A re-analysis of the Ghedotti’s (1998) matrix was performed
with TNT, by using implicit enumeration under equal and implied
weighting. The specimens from Río Arenales are separated in all
the analysis from J. alternimaculata, possibly conforming two different
species.
