[Effect of destruction of the median eminence on thermoregulation].
In male rats of 180-240 g weight, alterations of general thermoregulation and of functional activity of the suprarenal cortex, thyroid gland, and enterochromaffine system were studied after electrolytic lesion of the hypothalamic mesial eminence. In thermoneutral conditions, functions of the suprarenal cortex and thyroid gland remained unchanged while activity of the enterochromaffine system was reduced. Cooling decreased abruptly the reaction of thermoregulation and the functional activity of the endocrine glands. The data suggest the neurosecretory granules of the hypothalamic mesial eminence to participate in regulation of the organism temperature homeostasis in rats.
