[Somatotropin-releasing activity of rat hypothalamus with hypo- and hyperthyroidism].
The somatotropin-releasing activity of rat hypothalamus was studied in the experiments in vitro incubating of adenohypophysis with the hypothalamic extracts or the whole hypothalamus and serotonin. The studied activity is shown to be increased in the thyroidectomized and hyperthyroid rats. Exogenic somatotropin prevents this increase. A conclusion is drawn that a link of hypothalamic adenohypophysotropic hormones of the regulatory system of the somatotropic function is not an area of the specific disturbances with hypo- and hyperthyroidism which might lead to hyposomatotropism.
