Effect of exogenous glucagon on pituitary polypeptide hormone release
Metabolism, 1970Abstract Anterior pituitary hormone secretion following administration of crystalline glucagon was studied in three phases, i.e., after subcutaneous injection, after intravenous injection, and after intravenous injection during constant glucose infusion.

Pituitary growth hormone release in gonodal aplasia
The Journal of Pediatrics, 1968DR. 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 ...

Hypothalamic action of cachectin to alter pituitary hormone release
Brain Research Bulletin, 1989Cachectin (tumor necrosis factor, TNF) is a macrophage hormone which is released during infection and after injection of bacterial lipopolysaccharides. We have already demonstrated that the peptide has direct action on the pituitary to alter pituitary hormone release in vitro. To evaluate its action in vivo, we injected it into the third ventricle (3V)

Effects of Thymosin Alpha-1 on Pituitary Hormone Release
Neuroendocrinology, 1992The thymosins are a family of hormone-like products of epithelial cells of the thymus which are important in maintenance and function of the immune system. Thymosin fraction 5, a partially purified extract of calf thymus, can influence pituitary hormone release.

Hormonal Release by Dispersed Pituitary Cells
Canadian Journal of Physiology and Pharmacology, 1972Dispersed 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.

Peptides, 1983
The hypophysiotropic activities of a synthetic human pancreatic growth hormone releasing factor (hpGRF) with 40 residues was examined in vitro using rat pituitary halves. At concentrations from 10(-10) M to 10(-7) M the peptide stimulated GH release in a dose-dependent manner with the ED50 being 1.2 x 10(-9) M.

Fertility and Sterility, 1981
The effects of a 6-hour infusion with haloperidol on serum prolactin and luteinizing hormone (LH) levels was studied in a group of male subjects. Five hours after starting the infusions, a study of the pituitary responses to LH-releasing hormone (LH-RH) was carried out. Control patients received infusions of 0.9% NaCl solution.

Growth hormone-releasing hormone and pituitary somatotrope proliferation.
Minerva endocrinologica, 2003Growth 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.

Extra-pituitary inhibition of testicular function by luteinising hormone releasing hormone
Nature, 1979Luteinising 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, 1988Luteinizing 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.
