[Adaptive reactions of lipid metabolism in native and alien female representatives of Tofalaria population living under extreme environmental conditions].

Peculiarities of the state of lipid metabolism and of processes of lipid peroxidation--the antioxidant protection have been considered in female representatives of the native and alien population of Tofalaria in the age aspects. The obtained data indicate specificity of changes of level of parameters lipid metabolism not only in response to duration of effect of climatic factors, but also depending on belonging to different ethnic groups. Thus, in girls of the natural population of Tofalaria there is noted activation of adaptational-compensatory processes as compared with the alien ones, which is expressed as a significant decrease of atherogenic blood fractions and the general activation of the system of antioxidant protection. However, with age, in both ethnic groups a change of character of reactions of lipid peroxidation and lipid metabolism is noted, which is more expressed in the alien population.
