Cellular mechanisms of altered bovine luteal function in response to exogenous gonadotropin-releasing hormone

Creator:: Bertrand, Jennifer Elaine
Abstract:: To determine whether membrane-related events may be involved in attenuated luteal function after gonadotropin-releasing hormone (GnRH) administration, corpora lutea (CL) were removed from 10 beef heifers on day 7 of the estrous cycle after i.v. injection of GnRH or saline on day 2 of the cycle. Luteal slices were incubated...

Mechanisms of estradiol-17β-induced down-regulation of ovine uterine oxytocin receptors during the estrous cycle

Full Text:: to thank those faculty members who served on my graduate committee, especially Dr. Fred Menino for

Nongenomic inhibition of oxytocin binding by progesterone in ovine uteri

Creator:: Dunlap, Kathrin Anson
Abstract:: Effects of progesterone (P₄) and mifepristone (RU 486) on binding of oxytocin (OT) to its ovine uterine receptor (OTR) were studied in two experiments. Two additional experiments were conducted to evaluate specific binding sites for P4 in endometrial plasma membranes. In Exp. 1, ovariectomized ewes were injected with estradiol-17β (E₂)...

Nongenomic action of progesterone inhibits oxytocin signaling through the ovine oxytocin receptor

Creator:: Bishop, Cecily V.
Abstract:: Experiments were conducted to characterize the nongenomic effects of progesterone (P4) on binding of oxytocin (OT) to the ovine oxytocin receptor (OTR) and signal transduction. The dose-response relationship of P4 to OT binding to the OTR in endometrium was examined. Progesterone interfered with the binding of OT to the OTR...

Endocrinology of fur growth and reproduction in mink

Creator:: Rose, William Jackson
Abstract:: Experiments were conducted to determine: 1) the effects of exogenous melatonin and reduced photoperiod on molting and growth of the winter pelage (fur) and 2) whether changes in serum prolactin levels of treated and control mink during this same period were correlated with growth of winter fur. Adult and kit...

Bovine luteal oxytocin synthesis and secretion in vitro : effects of phorbol ester, calcium ionophore and indomethacin

Creator:: Cosola-Smith, Carrie A.
Abstract:: Experiments were conducted to examine the effects of a tumor-promoting phorbol ester, a calcium ionophore and indomethacin on bovine luteal oxytocin (OT) synthesis and secretion and progesterone secretion. Six 18-month-old crossbred beef heifers in Exp. 1 and five similar heifers in Exp. 2 were observed twice daily for estrus using...

Embryonic and hormonal control of ovine uterine arterial constriction

Creator:: Pope, William Frederick
Abstract:: The role of the conceptus and ovarian hormones in regulating ovine uterine vasoconstriction was investigated. The uterine artery ipsilateral to the ovary bearing the corpus luteum in ten nonpregnant and eight pregnant ewes was utilized in two experiments. Arteries of nonpregnant and pregnant ewes were removed at necropsy on day...

Photoperiodic effects on serum glucocorticoids and fur growth in mink

Creator:: Weiss, Deborah Ellen
Abstract:: The relationship of glucocorticoid secretion to light-induced, early-winter priming of pelage in ranch mink was investigated. Sixteen Standard Dark, mature, female mink were exposed to natural light conditions of 45° North latitude beginning on December 13, 1977. A 2x4 cm area of the right hip of each animal was sheared...

Some ovarian characteristics of the postpartum rabbit

Creator:: Gjesvold, James Allen
Abstract:: The effects of suckling on several ovarian characteristics were studied in postpartum rabbits. Ovarian weight was found to be significantly greater in rabbits suckled for twelve days than in nonsuckled rabbits autopsied at a similar interval postpartum or in a third group autopsied at parturition. There were no significant differences...

Some effects of estradiol on ovine luteal function

Creator:: Akbar, Abulfatah Maqsood, 1938-
Abstract:: Some effects of 171β-estradiol on ovine luteal function were studied in five experiments. Estradiol injected into ewes on days 11 and 12 of the estrous cycle caused luteal regression in both intact and unilaterally hysterectomized ewes indicating that the presence of one uterine horn permits estradiol to cause luteolysis comparable...
