Calcium Antagonists and Hormone Release: Effect of Nifedipine on Luteinizing Hormone-Releasing Hormone and Thyrotropin-Releasing Hormone-Induced Pituitary Hormone Release

The Journal of Clinical Endocrinology & Metabolism, 1983
In vitro evidence suggests that calcium is involved in the release of anterior pituitary hormones. Therefore, we studied the effect of the slow calcium channel blocker or calcium antagonist nifedipine on the FSH and LH responses to LRH and the TSH and PRL responses to TRH in vivo. Nine normal male subjects were studied on two occasions, and nifedipine

Selectivity of Melatonin Pituitary Inhibition for Luteinizing Hormone-Releasing Hormone

Neuroendocrinology, 1982
The pineal indole melatonin suppresses the neonatal rat luteinizing hormone (LH) and follicle-stimulating hormone (FSH) responses to LH-releasing hormone (LHRH), as shown in previous studies from this laboratory. We show in this study that the melatonin inhibition is a selective effect and is not due to general inhibition of pituitary function.

Luteinizing Hormone-Releasing Hormone in Human Pituitary Blood

Obstetrical & Gynecological Survey, 1978
✓ Luteinizing hormone (LH) and LH-releasing hormone (LHRH) were measured by radioimmunoassay in blood samples collected from the pituitary gland during transsphenoidal surgery in 19 patients. Detectable levels of LHRH were present in 12 patients. Wide fluctuations of LHRH were seen in sequential samples collected at 10-minute intervals, suggesting a ...
