Utilization of cytogenetic technics in paternity investigation.
The joint analysis of several genetic markers in cases of paternity investigation renders possible a cumulative probability of 99.7% of chance of exclusion of a falsely accused father. The role of heteromorphisms of the Y chromosome size was appraised in this work, with more than one genetic marker, in 20 expertise examinations in paternity investigation, where the children were male. The results found with this method, in association with the research on erythrocytic and leucocytic antigens showed the exclusion of two falsely accused men. Cytogenetics analysis with Giemsa stain in combination with leukocyte (HLA system) and erythrocyte antigens investigation demonstrated the exclusion of two men falsely accused.

A critical appraisal of the value of vaginal acid phosphatase determination for the estimation of post-coital time.
A careful literature review of the use of vaginal fluid acid phosphatase levels as a means to estimate post-coital time disclosed several inconsistencies. In this study, acid phosphatase levels were determined in vaginal fluid samples obtained from 200 women whose post-coital time was known. No statistical significance (at 5% probability levels) was found when vaginal acid phosphatase levels were correlated with post-coital time.

[Human experimentation: ethics and law].
The author justifies his work showing the need for standardization in experiments involving human beings. Major international and Brazilian regulations to that effect are referred to in order to establish main items that should guide an experimentation with human beings under ethical requirements.

[Sex determination in blood stains through identification of Y-chromatin: medico-legal application].
The Y-chromatin is visualized in human interphase nuclei, corresponding to the distal portion of the Y-chromosome, which shows marked fluorescence after staining with quinacrine. This report describes the results of sex determination on blood smears fixed in methanol and blood stains left at room temperature for 13 weeks (1st report), and for 10 months (2nd report). Blind trials showed that a reliable sex determination of blood stains on glass left for at least six months is possible. The application of this method in forensic practice is discussed.
