Individual and group peculiarities of adaptation in ontogeny (review and problem statement)

А complex of biochemical, hematologic and physiologic parameters determine individual variability that should correlate with general resistance of the organism. Hypoxia, a universal pathologic process is recommended as a model for studying individual adaptation in ontogeny. Hypophysis-adrenals system (HAS) activity may produce decisive effect upon the organism’s response reactions’ trend. HAS activity changes with age. Parallel to these changes resistance to hypoxia also alters. This process is gender-dependant. Individual and group peculiarities of resistance to acute hypoxia at various ontogenic periods should be compared to HAS functional state at respective periods separately for males and females. These correlations would facilitate better understanding of resistance variability general mechanisms characteristic of individual and group levels.
