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 ...

Growth hormone releasing factor increases growth hormone release from MtTW15 pituitary tumors

Brain Research, 1984
The MtTW15 pituitary tumor secretes growth hormone and prolactin. Perfusion of these dispersed MtTW15 tumor cells with 10 nM growth hormone releasing factor (GRF) increases growth hormone release without affecting prolactin release. This effect is dose-dependent between 0.001 and 0.1 nM and is blocked by 100 nM somatostatin. These findings suggest that

Factors Influencing Pituitary Glycogen Metabolism and Gonadotropic Hormone Release. I. Luteinizing Hormone-Releasing Hormone

Fertility and Sterility, 1974
The way in which luteinizing hormone (LH) and follicle stimulating h ormone (FSH) are related to pituitary glycogen metabolism is investigated by measuring pituitary glycogen content and the activity of glycogen synthetase and glycogen phosphorylase in LH-releasing hormone (LH-RH) treated rat pituitaries.

Modelling the Pituitary Response to Luteinizing Hormone‐Releasing Hormone

Journal of Neuroendocrinology, 2004
AbstractThe pituitary response to luteinizing hormone‐releasing hormone (LHRH) is steroid‐dependent and varies throughout the reproductive cycle, but the rapid rise in pituitary sensitivity on the day of the ovulation‐inducing LH surge is due to a ‘self‐priming’ effect of exposure to LHRH that results in a potentiation of pituitary responsiveness 35–40

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

Effects of cholinergic stimulation on pituitary hormone release

Psychoneuroendocrinology, 1982
Abstract Physostigmine was infused into human volunteers to assess the effect of central cholinergic stimulation on memory and on neuroendocrine function. Methscopolamine bromide, a peripheral anticholinergic agent, was given simultaneously. The lower dose of physostigmine (1.0 mg) produced no change in AVP, cortisol, melatonin, GH or LH in those ...
