Characterization of endothelin receptors in the anterior pituitary gland
American Journal of Physiology-Endocrinology and Metabolism, 1993To characterize endothelin (ET) receptors modulating pituitary hormone secretion, potencies of ET-like agonists were compared on prolactin (PRL), thyrotropin (TSH), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) secretion from primary cultures of female rat pituitary cells. ET-1 was more potent than ET-3 in all cases.

Anterior Pituitary — Six Glands and One
New England Journal of Medicine, 1972Though anatomically associated in a single structure, the anterior pituitary is made up of at least six different secretory types of cells, all capable of functioning independently of one another.

Characterization of Neurophysin in the Anterior Pituitary Gland of Sheep
Neuroendocrinology, 1988Portions of sheep anterior pituitary lobe tissue were extracted under acid conditions and assayed for the two neurophysins (oN-III and oN-I/II) by radioimmunoassay. In all tissues examined, oN-III and oN-I/II immunoreactivities were detected. Using a combination of isoelectric focusing and polyacrylamide gel electrophoresis, the neurophysins of the ...

Double tumors of anterior and posterior pituitary gland
Acta Neuropathologica, 1981Double tumors were found in the anterior and posterior lobes of pituitary gland at autopsy in a patient who presented with progressive deterioration of mental status. The chromophobe adenoma of anterior lobe consisted of a mixture of non-immunoreactive hormone containing cells and a few prolactin (PRL) and growth hormone (GH) cells in the mid portion ...

The anterior pituitary gland (adenohypophysis) influences a variety of biologic processes through the secretion and release of polypeptide and glycoprotein hormones (Harris and Donovan, 1966; McCann and Porter, 1969). Body growth is regulated through the synthesis and release of growth hormone (somatotropic hormone, STH), while the structure and ...

Control of Ovulation by the Anterior Pituitary Gland
1972Publisher Summary This chapter discusses control of ovulation by the anterior pituitary gland. Arguments are brought forward in the chapter pointing to the participation of structures situated outside the preoptic area and the hypothalamus in spontaneous ovulation.

The anterior pituitary gland: Lessons from livestock
Domestic Animal Endocrinology, 2005There has been extensive research of the anterior pituitary gland of livestock and poultry due to the economic (agricultural) importance of physiological processes controlled by it including reproduction, growth, lactation and stress. Moreover, farm animals can be biomedical models or useful in evolutionary/ecological research.

Sex Differences in the Anterior Pituitary Gland
1985This chapter will review many of the sex differences we and other investigators have observed on the morphology and physiology of the anterior pituitary gland of the laboratory rat. Occasionally similarities and differences in other species are mentioned. When known, the age of onset and the underlying mechanisms of the sex differences are discussed.

CONTROL OF PROTEIN SYNTHESIS IN ANTERIOR PITUITARY GLAND
Acta Endocrinologica, 1973ABSTRACT Chronic administration (6 days) of LH-RH to adenohypophyseal cells in monolayer culture leads to a 4-fold increase of the total content (cells plus medium) of radioimmunoassayable LH. A 75 % increase was observed at an initial concentration of 1 × 10−10 M LH-RH while a progressive increase to 300 % over control was measured at a ...

Hypothalamus: Anterior Pituitary Gland
1971Prior to 1940 very few definitive studies were done concerning the effects of narcotic analgesics on endocrine function. In general most of the early reports dealt with either the toxicity of morphine following extirpation or administration of endocrine tissue or morphological changes in endocrine organs after administration of the drug. These data are
