Prolactin Inhibits Pituitary Luteinizing Hormone-Releasing Hormone Receptors in the Rat
Endocrinology, 1982Pituitary LHRH receptors were studied in intact immature and mature female rats as well as in adult castrated animals of both sexes under experimental conditions leading to marked alterations of plasma PRL levels. Implantation of three anterior pituitary glands under the kidney capsule on the morning of estrus prevented the increase in pituitary LHRH ...

Clinical Endocrinology, 1976
SummaryIntrajugular administration of LHRH (0.6 and 1.2 μg) in hypophysectomized rats which received renal grafts of anterior pituitary induced a small but significant rise in plasma GH 5 and 10 min post‐treatment. LHRH, at the same dose levels, was ineffective in weight‐matched intact controls.

Galanin modulates pituitary hormones release.
Neuro endocrinology letters, 2006Galanin and its receptors are widely distributed within the central and peripheral nervous system, especially in hypothalamus including preoptic area, paraventricular nucleus (PVN), supraoptic nucleus (SON) and median eminence. Galanin plays an important role in the control of food intake, energy expenditure, reproduction, water balance and various ...

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.
