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

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)...

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...

Influence of castration and estrogen replacement on sexual behavior in hetersexual, male-oriented and asexual rams

Secretion of luteinizing hormone in response to exogenous melatonin in postpartum beef cows and ovariectomized beef heifers

Creator:: Sucheta, Susan Leers
Resource Type:: Dissertation

Corpus luteum function in hysterectomized and unilaterally hysterectomized ewes treated with gonadotropin-releasing hormone

Creator:: Whitmore, Diana L.
Resource Type:: Masters Thesis

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...

Gonadotropin releasing hormone-induced alteration of corpus luteum function in beef heifers

Creator:: Rodger, Lynn Dian
Abstract:: Two experiments were conducted to evaluate the effects of gonadotropin releasing hormone (GnRH) on the function of the bovine corpus luteum during the estrous cycle. In Experiment 1, 10 heifers were assigned randomly into two groups with each heifer serving as her own control. Heifers in Group I (n=5) were...

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...
