INHIBITION BY OESTRADIOL OF THE PITUITARY RESPONSE TO LUTEINIZING HORMONE RELEASING HORMONE IN THE DOG

Journal of Endocrinology, 1976
SUMMARY Intravenous injections of synthetic LH-RH stimulated LH secretion in male dogs. Pretreatment with 50 μg oestradiol-17β, 60 or 165 min but not 15 min before LH-RH, inhibited LH secretion. Injection of 0·1–10 μg oestradiol 165 min before administration of LH-RH, blocked LH secretion.

Extra-pituitary inhibition of testicular function by luteinising hormone releasing hormone

Nature, 1979
Luteinising hormone releasing hormone (LHRH), produced by the hypothalamus, stimulates gonadotropin production by the pituitary1–3. Paradoxically, chronic treatment with large doses of LHRH or its agonists causes a decline in testicular steroidogenesis and testicular LH/human chorionic gonadotropin (hCG) receptors; they also cause a decrease in the ...

Extra-pituitary action of luteinizing hormone releasing hormone on intraocular pressure

Current Eye Research, 1988
Luteinizing hormone releasing hormone (LHRH) given intraventricularly caused a delayed, significant decrease of intraocular pressure (IOP) in adult female rabbits for a prolonged period, but only elevated plasma gonadotropins for a few hrs. Intravenous injections of LHRH caused a similar elevation of plasma gonadotropins without any effect on IOP.

Growth hormone-releasing hormone and somatostatin in normal and tumoral human pituitaries

Peptides, 1991
In order to further understand the role of endogenous pituitary neuropeptides in pituitary hormonal content and secretion, GHRH, SRIH and GH contents were quantified in GH adenomas obtained from acromegalic patients with plasma GH levels either high (greater than 5 micrograms/l, range 11 to 550 micrograms/l, n = 11) or in the normal range (less than 5 ...

Sexual dimorphic porcine pituitary response to growth hormone-releasing hormone

Domestic Animal Endocrinology, 1990
The aim of this study was to compare growth hormone (GH) response of barrows and gilts to porcine growth hormone-releasing hormone (pGRH) at the pituitary level. Anterior pituitary cells from barrows and gilts responded to pGRH in a dose-dependent manner.

Hormonal Release by Dispersed Pituitary Cells

Canadian Journal of Physiology and Pharmacology, 1972
Dispersed anterior pituitary cells were prepared by treatment of hog pituitaries with collagenase. The cell yield based on DNA recovered in intact cells after collagenase treatment was 5–10%. Ninety percent of the cells appeared intact by phase contrast microscopy. The three major cell types were identifiable by Mallory-Heidenhain staining.

Pituitary growth hormone release in gonodal aplasia

The Journal of Pediatrics, 1968
DR. WHITTEN. At the moment, it seems to me that the evidence in support of the sensory deprivation hypothesis is far more vulnerable to the type of criticism you have introduced than are our data which support the nutri t ional deprivation hypothesis. We have gone fur ther in eliminating the possibility of the psychologic factors being misinterpreted ...

Growth hormone-releasing hormone and pituitary somatotrope proliferation.

Minerva endocrinologica, 2003
Growth hormone-releasing hormone (GHRH) is a hypothalamic hormone that is essential for normal expansion of the somatotrope lineage during pituitary development. Decreased GHRH secretion and/or action leads to impairment of this process and somatotrope hypoplasia in both humans and experimental animals.
