Yasinska O. Peculiarities of photoperiodical changes of prooxidant processes, antyoxidant system and the adrenals under the influence of the exogenic hypoxia

The thesis is dedicated to experimental investigation of the reaction peculiarities of prooxidant processes, antyoxidant system, structure and function of the adrenals onto the intermitten hypobaric hypoxia and varying duration of photoperiod in albino rats of different age and sex. There were esteblished the age- and sex-dependent dependent differences in the reactions pro- and antyoxidant systems in the blood plasma and the adrenals onto the hypobaric hypoxia and varying duration of photoperiod. On a bases of the level of glucocorticoids in the blood serum and histological findings in the adrenals it is concluded that the reaction of adrenals onto the combined influence of hypobaric hypoxia and varying duration of photoperiod depend on the epiphyseal function, age and sex.
