[Effect of thymectomy on the functional activity of the thyroid gland in rats]

The authors examined the functional state of the thyroid gland of rats after thymectomy. The dynamics of incorporation of radioactivity I131 in the gland was examined on the 2,20 and 90th day after the operation. There was increased incorporation of the radioisotope in the thyroid giant at the early stages of the experimental period. A reduced incorporation and delayed excretion was observed in the distant periods. Changes in the activity of the thyroid gland were accepted as a manifestation of the existing functional link between the thymus and thyroid gland.
