The Changes of Thyroid Gland Morphofunctiona! Condition under Combined Exposure of Hypokinezia and Cold
The obtained data of morphofunctional condition and blood hormone levels of rats thyroid glands under 5 days exposure of hypokinezia, cold and their combination are presented. It was established that cold exposure in combination with hypokinezia gave rise to compromising reaction of thyroid gland, when there were elements of reaction to both hypokinezia and cold. Some of follicles in central gland,s zone were in condition of great functional stress, but the rest of part (it was more than 2 volume) was in deep depression of synthesis and secretion. So considerable deficiency of thyroid hormones in organism appeared and it lead to heavy breach of metabolism, weakening of the mechanisms of thermoregulation and even to the death of some rats at the end of the experiment.
