[The effect of the 120-day antiorthostatic hypokinesia on the functional state of female thyroid].

Investigations of eight healthy female volunteers aged 26-37 in 120-days antiorthostatic hypokinesia (AOH, -5 degrees) gave original data about peculiarities of adaptation and functional state of female thyroid and the thyreotrophic activity of adenohypophysis. The test-subjects were divided into two equal groups. Group 1 administered a set of countermeasures including exercise and pharmacy. In the other group, no health control was used. By days 90-100 in AOH thyroid glands of the females were slightly more compact but remained diffuse. Thyroid sizes were not altered. Chemical/biochemical examination did not elicit any noteworthy shifts in the thyreotrophic activity of hypophysis or thyroid function in the bedrested females. The countermeasures did not enhance the thyroid function. Results of the investigation point to the completion of thyroid adaptation of females by days 90-100 in AOH.
