Restructuring of the thyroid gland in primary hypothyroidism under the influence of intermittent hypobaric hypoxia.

We studied the effect of intermittent hypobaric hypoxia on morphofunctional characteristics of the thyroid gland during experimental hypothyroidism. Functional activity of the thyroid gland increased in the early period of hypoxia. Morphofunctional parameters reached a constant level with increasing the duration of hypoxia to 7-15 days. A new functional level was characterized by increased activity and normal function of glandular cells.
