Features of compensatory-adaptive reactions of an organism in female representatives of the Evenk ethnos

Adolescent girls and women of reproductive age, female representatives of the Evenk ethnos and Europeoids that co-inhabit the north of the Irkutsk oblast, were examined. Changes in metabolic reactions in the small indigenous ethnic group were found to have a more adaptive character than in the Europeoids. In the Evenk vs. Europeoid girls, an increased activity both of glucocorticoid function of the adrenal glands and non-enzymatic antioxidant defense system was detected. In spite of the higher total cholesterol (TCh) level in women vs. girls in both ethnic groups, in the Evenk group TCh tended to decline. Changes in the antioxidant defense system of the Evenk women manifested themselves as an increased total antioxidant activity of blood vs. Europeoids as well as higher TCh and lower retinol levels vs. adolescent girls.
