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.

Molecular and Cellular Endocrinology, 1978
A method has been developed for disaggregating porcine anterior pituitary tissue and for providing dissociated preparations which have good, stable viability in culture. The secretory capacity for these preparations in terms of their ability to release luteinizing hormone in response to luteinizing hormone-releasing hormone has been documented in ...

Effect of hydrocortisone on the pituitary response to growth hormone releasing hormone
Psychopharmacology, 2000In depression, the growth hormone (GH) response to clonidine and L-tryptophan (L-TRP) is reduced, suggesting reduced alpha2-adrenergic and serotonin (5-HT)1A receptor function. Pretreatment with hydrocortisone (100 mg, orally 11 h before) also blunts the GH response to L-TRP.

Immunocytochemistry of a ?private? luteinizing-hormone-releasing hormone system in the pituitary
Cell and Tissue Research, 1984Immunocytochemistry of paraffin sections of Bouin-fixed rat pituitaries with antiserum to luteinizing-hormone-releasing hormone (LHRH) revealed two types of cells. Type I cells exhibit granular staining throughout their cytoplasm. The immunoreactivity of type II cells is confined to a much smaller area of the cytoplasm.

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 ...

Growth hormone releasing factor increases growth hormone release from MtTW15 pituitary tumors
Brain Research, 1984The 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

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)

The role of immunopeptides in the regulation of anterior pituitary hormone release
Trends in Endocrinology & Metabolism, 1990The anterior pituitary lobe secretes hormones that regulate the functioning of the immune system which, in turn, produces thymic hormones and interleukin proteins capable of altering neuroendocrine responsiveness. Interleukin-1 is released during inflammation and activates the hypothalamic-pituitary-adrenal axis, which subsequently diminishes the ...

Potentiation of Luteinizing Hormone Release by Estradiol at the Level of the Pituitary
Neuroendocrinology, 2008The objective of this study was to determine the influence of estradiol-17β and/or progesterone on gonadotropin secretion at the level of the pituitary. Female rats in which the hypothalamo-hypophyseal connections had been permanently interrupted after castration served as the experimental model in which the effect of estradiol and/or progesterone on ...

Detection of gonadotropin-releasing hormone receptor in normal human pituitary cells and pituitary adenomas using immunohistochemistry [PDF]
Virchows Archiv Fur Pathologische Anatomie Und Physiologie Und Fur Klinische Medizin, 2000 Gonadotropin-releasing hormone (GnRH), which is a well-known regulator of gonadotroph function, has recently been considered to be a paracrine factor involved in the control of somatotroph, lactotroph, and corticotroph cells.
