Physiological factors affecting ovine uterine estrogen and progesterone receptor concentrations

Creator:: Prater, Patrice L.
Abstract:: Two experiments were conducted to determine whether in ewes uterine concentrations of estrogen and progesterone receptors are affected by the presence of a conceptus or by the hormonal milieu associated with extremes in photoperiod to which ewes are exposed. In Exp.1, nine mature ewes were unilaterally ovariectomized by removing an...

Response of the bovine corpus luteum to exogenous gonadotropin-releasing hormone during the estrous cycle

Creator:: Martin, Teri L.
Abstract:: Two experiments were conducted to investigate the effects of gonadotropin-releasing hormone (GnRH), administered twice during the same estrous cycle, on bovine luteal function. Eight mature beef cows, each cow serving as her own control, were injected intravenously (i.v.) with saline on days 2 and 8 of the cycle (day of...

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...

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...

Oxytocin synthesis and release by the bovine corpus luteum

Creator:: Abdelgadir, Salaheldin Eltigani
Abstract:: Four experiments were conducted to determine oxytocin concen tration of bovine luteal tissue at different stages of the estrous cycle and to study the effects of prostaglandins F₂α (PGF₂α), E₂ (PGE₂), luteinizing hormone (LH), cycloheximide, colchicine and cytochalasin B on oxytocin synthesis and release in vitro. In experiment 1, luteal...
