Searching for an inhibitory action of blood-borne [beta]-endorphin on LH release
Autor: P. V. Malven
Publikováno v: Bioscientifica Proceedings.
Concentrations of beta-endorphin were quantified in peripheral blood plasma of sheep by a radioimmunoassay that cross-reacted with beta-lipotrophin. Plasma concentrations of beta-endorphin increased abruptly after physical confinement, bacteraemia, a

Serum concentrations of luteinizing hormone, growth hormone, and prolactin in untreated and estradiol-treated ovariectomized ewes after immunoneutralization of hypothalamic neuropeptide Y
Autor: P V, Malven, S A, Haglof, H, Jiang
Publikováno v: Journal of animal science. 73(7)
Ovine antiserum against a conjugate of porcine neuropeptide Y (NPY) with bovine thyroglobulin was infused repeatedly into one lateral ventricle of five ovariectomized (ovx) ewes before and after subcutaneous injection of estradiol-17 beta (E beta). S

Intracerebral methionine-enkephalin, serum cortisol, and serum beta-endorphin during acute exposure of sheep to physical or isolation stress
Autor: T, Hashizume, S A, Haglof, P V, Malven
Publikováno v: Journal of animal science. 72(3)
In vivo microdialysis was used to estimate extracellular concentrations of methionine-enkephalin in 19 brain sites for 5 h on each of three consecutive days (trials) in six conscious ewes. Following control procedures on d 1, ewes were completely iso

Transcription of prolactin gene in milk secretory cells of the rat mammary gland
Autor: R. W. Steinmetz, P. V. Malven, A. L. Grant
Publikováno v: The Journal of endocrinology. 136(2)
In-situ hybridization and Northern blot hybridization were used to identify mRNA for pituitary prolactin in mammary tissue obtained from female rats 1 day before expected parturition, 1 day after parturition and on day 7 of lactation. Prolactin cDNA

Effects of Intraventricular Infusion of Serotonin, Norepinephrine, and Dopamine on Spontaneous LH Release in Castrate Male Sheep1
Autor: B. L. Riggs, P. V. Malven
Publikováno v: Biology of Reproduction. 11:587-592
Various dosages of serotonin (5-HT), norepinephrine (NE), and dopamine (DA) were infused into the third ventricle of the hypothalamus of unanesthetized castrate male sheep. Sequential blood samples were collected at 10-mm intervals from indwelling va

Stimulation of Prolactin Release in Vivo by Thyrotropin-Releasing Hormone (TRH) Through Direct Action on the Ectopic Rat Pituitary1
Autor: P. V. Malven, S.E. Porteus
Publikováno v: Endocrinology. 94:1699-1703
Hypophysectomized female rats which had received renal grafts of anterior pituitary (AP) were sampled by heart puncture under pentobarbital (PB) anesthesia. Serum prolactin in sequential samples from each rat was measured by radioim-munoassay to dete

Bacteremia-induced changes in pituitary hormone release and effect of naloxone
Autor: P. V. Malven, L. S. Leshin
Publikováno v: American Journal of Physiology-Endocrinology and Metabolism. 247:E585-E591
Acute bacteremia in sheep caused a surge of plasma beta-endorphin/beta-lipotropin (beta-EP/beta-LPH) associated with shivering behavior, tachycardia, hyperthermia, hemoconcentration, and decreased respiration rate. The surge of plasma beta-EP/beta-LP

Experimental Alterations of Prolactin Levels in Goat Milk and Blood Plasma1
Autor: P. V. Malven, J. P. Mcmurtry
Publikováno v: Endocrinology. 95:559-564
Previous research demonstrated the presence of substantial amounts of prolactin in the milk of several species. In the present experiments plasma prolactin levels in goats were experimentally altered and prolactin concentrations in milk were determin

Immediate Release of Prolactin and Biphasic Effects on Growth Hormone Release Following Electrical Stimulation of the Median Eminence1
Autor: P. V. Malven
Publikováno v: Endocrinology. 97:808-815
The median eminence (ME) region of the hypothalamus was electrically stimulated through permanently implanted electrodes in 4 unanesthetized sheep. Plasma concentrations of GH and prolactin (PRL) were measured at 10-min intervals before, during and a
