[The gene pool of Belgorod oblast population: study of biochemical gene markers in populations of Ukraine and Belarus and the position of the Belgorod population in the Eastern Slavic gene pool system].

The characteristics of the gene pools of indigenous populations of Ukraine and Belarus have been studied using 28 alleles of 10 loci of biochemical gene markers (HP, GC, TF, PI, C'3, ACP1, GLO1, PGM1, ESD, and 6-PGD). The gene pools of the Russian and Ukrainian indigenous populations of Belgorod oblast (Russia) and the indigenous populations of Ukraine and Belarus have been compared. Cluster analysis, multidimensional scaling, and factor analysis of the obtained data have been used to determine the position of the Belgorod population gene pool in the Eastern Slavic gene pool system.

[Role of hereditary factors in the formation of secondary insulin dependence in patients with type II diabetes mellitus].

A total of 389 patients with diabetes mellitus were examined. A genetic analysis has shown a most high possibility of diabetes in the sibs of patients with type II diabetes and secondary insulin dependence. The authors put forward a hypothesis that secondary insulin dependence formation in diabetics with type II condition results from interactions of two gene complexes with a recessive effect, responsible for types I and II diabetes mellitus development.
