BIOCHEMICAL SPECTRUM OF BLOOD SERUM AS INDICATOR OF YAKUTIA RESIDENTS ADAPTEDNESS TO NORTHERN CONDITIONS

The analysis of lipid metabolism in the population of Yakutia has revealed high percentage of disturbed lipid metabolism both among the indigenous and alien population of Yakutia. The high frequency of dyslipidemia and hypercholesterolemia at the young age in the alien residents of Yakutia is one of the indicators of lower body adaptive reactions. For detection of maladaptation and timely preventive actions, it is necessary to identify informative biochemical methods that characterize body functional states. The sample of 1 422 residents of Yakutia aged 18 to 72 y. o. has been examined. The number of indigenous residents of Yakutia was 758 persons (the mean age 45.02 ± 3.54 years), the alien population - 664 (the mean age 43.67 ± 2.61 years); the women - 878, the men - 544. Dyslipidemia was associated with activity of the enzymes characterizing the body energy needs depending on the degree of adaptedness to climatic and geographical conditions of Yakutia. There have been obtained significant differences of the enzymes activity indicative of different intensity of adaptive metabolic processes in high latitudes depending on ethnicity. During prophylactic medical examinations of the population for identification of disease onset risk groups and development of preventive measures to restore the body reserves, attention should be paid to the serum enzymes activity. De Ritis ratio can serve as one of the criteria of assessment of the body adaptive reactions to uncongenial climatic-geographic factors.
