[The influence of normobaric hypoxia on the morphofunctional changes of thyroid gland in young rats].


PMID 23957166

Abstract

We investigated the influence of hypoxic gas mixture (the different modes) on the morphometric indexes of thyroid gland functional activity in 3-mounth rats. It was shown a decrease in the size of follicles of middle area and the colloid and an increase in the amount of thyrocytes in a follicle, resorption vacuoles and interfollicular epithelium after exposure to hypoxic gas mixture (10% oxygen). We also detected an increase in a follicle-colloid index and a decrease in the colloid accumulation index. Thus, a dosed normobaric hypoxia intensifies the functional activity and physiological regeneration processes of thyroid gland in the young animals.
