Growth hormone, prolactin and insulin following arginine infusion in primary hyperparathyroidism before and after parathyroidectomy

Abstract

Abstract. The secretion of growth hormone, prolactin and insulin following arginine infusion was studied in 9 patients with primary hyperparathyroidism before and after parathyroidectomy. Growth hormone, insulin and glucose levels after arginine administration were significantly higher before parathyroidectomy compared with the corresponding data obtained in the post-operative state, whereas plasma prolactin concentrations did not differ before and after operation.
