[The forensic medical evaluation of traumatic and spontaneous ruptures of the organs affected by the tumours].

The present article was designed to report the results of the analysis of the cases of traumatic and spontaneous ruptures of the organs affected by the tumours based on the original observations and the literature data. It is shown that the probability of the tumour rupture depends on its histological type, localization, the size, and the distance from the capsule of the affected organ, the degree of involvement of the major blood vessels, the severity of the necrotic changes, the presence of cysts in the neoplasm, and the regimens of radio- and chemotherapy. Moreover, the rupture can be facilitated by anticoagulation therapy, intake or oral contraceptives, pregnancy, concomitant diseases, alcoholic intoxication, splenomegaly, and hypocoagulation resulting from dissemination of the neoplastic process or the metastatic lesions of the liver.

[Sudden death in cancer pathology forensic-medical characteristics].

The article presents a review of references on causes of sudden death of persons suffering from oncological diseases. The paper describes the main mechanisms of sudden death of persons with cancer who are subjected to forensic-medical research. Data on the structure of sudden death for the last 10 years are demonstrated.

[Population genetics of taiga hunters and reindeer breeders in central Siberia. The biochemical markers of genes Hp, Tf, Gc, A1b, GLO1, PGM1, AcP and EsD].

Biochemical markers of gene systems Alb, Tf, Gc, Hp, GLO1, PGM1, EsD, AcP were analysed in the native population of Evenc national region. It is shown that native population of Central Siberia, in spite of its mongoloid racial type, posseses the complex of gene frequencies for protein loci studied which is not typical for mongoloids. The complex may be called "central-siberian" and its origin may be connected with the process of adaptation to environment of the Central Siberian geographical region.

[Correlation of heredity and environmental factors in the etiology of Vilyui encephalomyelitis. II. A population genetic study in districts of Vilyui encephalomyelitis distribution].

Population-genetic investigation was carried out in the regions endemic for Viljuisk encephalomyelitis (VE). The following indices were estimated: the relationship coefficient, the inbreeding coefficient, the intensity of migration, genetic structure of the population. The aim of the investigation was to explain causes of intrapopulational and, in some cases, of intragenus accumulation of the VE patients.
