HGH secretion in response to TRH was studied in patients with cerebrovascular disease in order to elucidate an influence of cerebrovascular lesions on the hypothalamus-anterior pituitary function. Blood specimens were obtained before and at the time of 10, 20, 30, 40, 60, 90 and 120 minutes after the intravenous administration of 500 big of TRH in 17 patients with cerebral hemorrhage and in 8 patients with cerebral infarction. With regards to the natural fluctuations of serum HGH caused by cerebrovascular disease, the blood specimens were obtained at the time of 0, 30, 60, 90 and 120 minutes without the administration of TRH in 4 patients with cerebral hemorrhage and in 4 patients with cerebral infarction. Serum HGH was measured using the RIA method and the following results were obtained : 1) An increase in serum HGH was observed in 1 patient with cerebral hemorrhage out of 8 patients with cerebrovascular disease without TRH administration. 2) In 5 out of 17 patients with cerebral hemorrhage, an increase in serum HGH was observed following TRH administration. Three out of these 5 patient were female. 3) In 2 out of 8 patients with cerebral infarction, an increase in serum HGH was observed following TRH administration.
