- Total non-acid glycolipid fractions and total sodium dodecylsulphate (SDS) solubilized protein fractions were isolated from human thrombocytes obtained from single human donors having different blood group A1/A2 phenotypes. The blood group A glycolipid antigens were characterized by immunostaining of thin layer plates with different monoclonal anti-A antibodies. The glycoproteins carrying blood group A epitopes were identified by SDS-PAGE and Western blot analysis using a monoclonal anti-A antibody. Blood group A glycolipid antigens were found in both A1 and A2 thrombocytes but the A2 individuals expressed at least ten times less A glycolipids compared to the A1 individuals. Expression of A type 3/4 chain and small amounts of A type 1 chain glycolipids were seen in thrombocytes of both A1 and A2 individuals, while the type 2 chain A glycolipids appeared to be missing from the A2 thrombocytes. Blood group A reactive glycoproteins were only found in thrombocytes of A1 individuals and could not be detected in A2 individuals or a blood group O individual. The major blood group A glycoprotein were found as a double band migrating in the 130 kDa region.

- The objective of this study was to estimate the prevalence of mental disorders in the Subtiava district of León, Nicaragua. Two-stage cluster sampling was used to select 219 families (n = 584 persons). The study was carried out in two phases. In the first, probable mental disorder cases were screened using the Self-Reporting Questionnaire. In the second, the diagnoses were confirmed through the Present State Examination questionnaire. The validity and reliability of the questionnaires had been confirmed in a pilot study. The present study was conducted in October and November 1987, when Nicaragua was still immersed in armed conflict. Construction of a family map made it possible to analyze, through the multiple imputation method, the characteristics of persons who were absent at the time of the interviews or who did not respond. The estimated prevalence percentages and their respective 95% confidence intervals were as follows: neurosis, 7.5% (5.2%-9.8%); depression, 6.2% (2.6%-8.1%); reactive crisis, 3.3% (2.6-6.5%); alcoholism, 5.8% (3.9%-8.9%); organic brain syndrome, 3.9% (1.7%-5.2%); psychosis, 0.5% (0.2%-1.6%); and other disorders, 0.7% (0.2%-1.6%). The estimated overall prevalence of mental disorders in the study population was 27.9%. Disorders were more prevalent among men (30.8%) than women (26.3%). It is concluded that these high estimated prevalences are associated with stress caused by the war.
