PURPOSE: to verify the effectiveness of the maternal blood serum assays of the atrial natriuretic peptide (ANP) and nitric oxide (NO) to predict pregnancy complications. METHODS: the sample was made of 49 primigravidae women. They were included in the study at the 18th week of gestation, when blood sample was collected in order to analyze the serum assays. ANP was assayed by radioimmunoassay, using Euro-dianostica kits (2000), considering abnormal values over 237.4 pg/ml (95 percentil). NO level was evaluated by the chemiluminescence method, considering abnormal values over 17.8 mmol/l (percentil 95). For the statistical analysis of continuous quantitative variables with normal distribution, the unpaired t test was used; Mann-Whitney’s test was used for non parametrical quantitative samples; Fisher’s exact test, for the qualitative parameter assessment; and Pearson’s test for the assessment of correlations. RESULTS: there was no significant difference in the blood serum concentration of ANP between the group that presented complications during pregnancy and/or peridelivery (139.3±77.1 pg/ml) and the control group (119.6±47.0 pg/ml), nor in the serum concentration of NO, either, among the ones with complications in the pregnancy and/or in the peridelivery (11.1±4,6 mmol/l) and the control group (10.0±3.4 mmol/l). CONCLUSIONS: the results show that ANP and NO serum levels are not good predictors of pregnancy complications.

PURPOSE: to verify the amount of CD68+ cells in chorionic villosities in placentae from gestations submitted or not to labor. METHODS: transversal study with healthy near-term pregnant women, among whose placentae, 31 have been examined by immunohistochemical technique. Twenty placentae were obtained after vaginal delivery (VAGG) and eleven after elective cesarean sections (CESG). Slides were prepared with chorionic villosities samples and labeled with anti-CD68 antibody, specific for macrophages. Labeled and nonlabeled cells were counted inside the villosities. Non-parametric statistical tests were used for the analysis. RESULTS: among the 6,424 cells counted in the villosities' stroma from the 31 placentae, 1,135 cells (17.6%) were stained by the CD68+. The mean of cells labeled by the anti-CD68 was 22±18 for the VAGG group and 20±16 for the CESG, in each placentary sample. CONCLUSIONS: there were no significant differences in the percentage of macrophages (CD68+) in association with labor.
