[The characteristics of changes of indicators of hypophyseal-thyroid system and lipid metabolism in adolescents of different ethnic groups].

The girls and boys (the ethnic tofs) residing in the village of Alykdjer of Nijneudinsky district of Irkutsk oblast have been examined. The Irkutsk girls and boys (the Caucasians) made the comparison groups. In tof boys the activation of hypophyseal-thyroid system and activity increase of lipoprotein spectrum of blood serum was established.

[An ecogenetic approach to studying the adaptation and human health].

Genetic markers--blood groups ABO, RH, MN; serum proteins HP, PI, TF, C3; erythrocyte enzymes ACP1, ESD, AK1, PGM1, GLO1, PGD, PGP; and the other: PTC-tasting, ear wax types and color vision, were studied in two aboriginal Buryatian populations of Baikal Lake region: in Chitinskaya and Irkutskaya Provinces. Two samples were further divided into subgroups, according to their health status: "healthy", "indefinite" and "sick" by means of special regression procedure. The "healthy" subgroup of the Chitinskaya Province population is characterized by higher frequencies of PTC-tasters: 0.

[Nonspecific inherited risk factors for acute respiratory diseases in children living in the western part of the Baikal-Amur railway].

Variation of 9 polymorphic loci was compared in 2 groups of children from Russian native and migrant population of Western area of Baikal-Amur Railway--those who suffered from acute respiratory diseases during first year of life and their parents, and normal children and their parents. Frequencies of genotypes 1-1 (HP locus). 00 (ABO locus), and pp (F locus) were significantly higher in normal children than in the affected ones.

[Variability of anthropometric traits at birth in healthy children and children suffering from acute respiratory diseases in the first year of life].

Variation of 5 anthropometric traits at birth in groups of normal children who had suffered from acute respiratory diseases during their first year of life was studied in Russian migrant and native population inhabiting the Western area of Baikal-Amur Railway. It was shown that affected children from migrant and native population had lower average values of all traits, as compared with normal children. In order to reduce the number of variable, the principal component analysis was applied.

[Comparative study of the variability of morpho-physiological traits and polymorphic genetic markers in migrant and local Russian population of the Western region of the Baikal-Amur railway].

Morpho-physiological traits and variation of gene markers of 119 complete families from Russian migrant population inhabiting the Western area of Baikal-Amur Railway and 92 such families from Russian native population from the same area were compared. In migrant women body length was 2 cm higher and age of menarche was 8 months earlier than in native population. Average values of 5 anthropometric measurements of newborns in migrant population were higher than in native population.
