[Functional state of the thyroid gland following exposure to ultrasound].
Changes are described in the content of butanol-extracted iodine in the blood serum and total iodine in thyroid tissue of white rat males under ultrasonic effect of various intensity (0.2, 0.6, 1.0 Watt/cm2) and analysed at different time intervals after ultrasound application. A decrease in total iodine content in thyroid glands (at initial level 0.315 mg%) and an increase of butanol-extracted iodine content in the blood serum were observed in all the experimental groups. The data obtained compared with the earlier found increase of the thyroid hormone content in the serum and thyreotropic hormone at a decreased content of thyroxins in the thyroid gland seem to point to the activation of the thyroid function after the application of ultrasound.
