Outlined in the paper are outlooks for determining a group affiliation of sperm in traces, left in material evidence, within forensic biological expertise. A technique is suggested to separate the spermatozoids from the vaginal epithelium cells--it has been used up to now in genetics alone. The method involves the available reagents and does not need any extra training. Its elaboration and introduction would resolve one of the most often-encountered issues set by the investigating office. 相似文献

Forensic medical service is constantly updated, which is confirmed by introduction of new modern methods, such as detection of blood or semen with test strips, new modifications of methods for handling bone material, differentiation of blood of the same group within ABO system, identification of blood groups in mixed stains of blood of humans and some animals, use of gel plates, etc. Methodological and information letters have been issued and field seminars are regularly carried for upgrading expert biologists. The overwhelming majority of expert biologists have received specialized education and topical upgrading. 相似文献

In this article the authors give a scientific evaluation of genetic dactyloscopy method in which the sites of human chromosomal DNA, possessing structural polymorphism, act as genetic markers. Technology of genome "dactyloscopy" including both the series of standard conventional methods and new methods is presented. The method is highly sensitive and requires small amounts of material for investigation. A practical case is described when genome "dactyloscopy" gave positive results which led to a conclusion on suspect's involvement in the crime. 相似文献

Use of DNA "fingerprinting" method for biological analysis of material evidences exhibit new potentials for making concrete expert conclusions. But such expertise is time consuming and difficult to perform that's why it is important to evaluate fitness of expert material for DNA fingerprinting at early stages of object investigation. Method of preliminary treatment of objects sent for DNA fingerprint expertise in case of sexual assault is suggested and tested. This method allows one to evaluate objects easily from the standpoint of possibility to perform such investigation. 相似文献

A comprehensive series of experiments was undertaken to find the reasons why the cigar-butt stuff, removed from accident places for investigation at forensic-biological laboratories, affects different sera. A number of such reasons were established. Methods are suggested to eliminate the cigar-butt impact with the aim of ensuring the most accurate results while determining the group adherence of saliva on the cigar-butts. 相似文献

Fluorat-02-3M liquid analyzer essentially extends the range of hemoglobin measurements, increasing its concentration in the studied extract from 0.1 to 100 micrograms in a 100 microliters sample (the lower threshold concentration remains unchanged: 0.005 in a 100-microliters sample) in detection of the blood in stains on material evidence pieces by fluorescent hemotest. This allows detection of blood in both washed and clearly seen blood stains on pieces of material evidence. Examples of using this method for measuring mass concentrations of zinc in water extracts on a Fluorat-02-3M analyzer are presented. The analyzer was developed at the Bureau of Forensic Medical Expert Evaluations of the Leningrad region for tentative detection of seminal fluid in stains on material evidence pieces. The results of this method are objectively recorded. 相似文献
