ADAPTIVE REACTIONS OF INDIGENOUS POPULATION OF YAKUTIA
Introduction:
The researches of organism's adaptive possibilities of indigenous population of the Arctic region are extremely important in modern conditions of the development of northern territories. The functional reserve of basic physiological systems and their interaction define "the health's resources", its potential level.
Aim:
This research has substantiated the adaptive reactions of organism of the North inhabitants on the basis of medical-physiological results.
Materials And Methods:
Physical development was estimated by the standard anthopometrical method: the height and body mass were measured, index of body mass (BM), Quetelet's index, Rohrer's index were defined, area of body surface was calculated. Carbon dioxide in the air was defined by portable infra-red gas analyzer of firm "Fudji" for measurements indoors and outdoors. The parametres of blood acid-base state (ABS) were analyzed by standard procedures with microevaluator application ABL-330 (Denmark). Computer spirometry was done on the hardware-software diagnostic complex (HSDC) for analyses of external respiration function (NSRIMT - Russia) and "Pneumoscrin-2" of Erih Eger company (Germany). Arterial pressure was measured by Korotkov's method.
Results:
The inhabitants of the North irrespective of ethnicity have conditions for more effective lung ventilation to satisfaction of the high metabolic requirements of the organism.
Conclusions:
Stability of arterial pressure among indigenous population, microcirculation optimisation and transcapillary tissues exchange, conserves steady level of metabolism that testifies a high level of adaptation of the person to severe climate- geographic North conditions.
