[Rodent thyroid gland function under hot climatic conditions]

Studies have been made on the effect of high temperature and intensive insolation upon the uptake of iodide and hormone formation in the thyroid of rodents (Rhombomys opimus, Spermophilopsis leptodactylus, Citellus fulvus) with different adaptation to the environment. It was shown that high temperature in combination with solar radiation significantly decreases functional activity of the thyroid and affects some of the physiological indices of the organism. Animals with different ecological specialization differ in their reaction to factors of the hot climate.
