Reactions of some endocrine glands in male infant rats to hypoxia at the second stage of sexual maturation

Mehbaliyeva Elnara Jabirovna

In the presented work, it was shown that with a one-time 20-minute severe form of hypoxia (85% N2 + 15% O2), hormonal reactions from the adrenal cortex, thyroid gland, and testes in 2-month-old male rat pups during the middle stage of puberty, ambiguous. The adrenocortical hormone (cortisone) in the blood plasma increases at the very first day of hypoxia, and then the reaction dies out. On the 3rd day of experiment the blood level of thyroid gland hormone (thyroxine) increases slightly, and the total testosterone (hormone of testicles and suprarenal cortex) remains within the reference values, and to the 5th day of experiment it decreases substantially in relation to the standard.
