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...

Gonadotropin releasing hormone-induced secretion of luteinizing hormone during the milk ejection reflex in the postpartum beef cow

Creator:: Jaeger, John Ralph
Abstract:: A study was conducted to determine the effect of the milk ejection reflex on exogenous gonadotropin releasing hormone (GnRH)- induced release of luteinizing hormone (LH) after short term calf removal. Twenty-four postpartum multiparous beef cows were assigned 3 randomly to groups arranged in a 2[superscript 3] factorial design to be...

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

Plasma membrane composition and luteinizing hormone receptors of ovine corpora lutea during early pregnancy

Creator:: Zelinski, Mary Beth
Abstract:: The lipid composition of plasma membranes of corpora lutea was examined to determine whether changes in this organelle occur during regression and early pregnancy in the ewe. Forty ewes were assigned to be necropsied on days 13 or 15 of the estrous cycle (D13-NP and D15-NP) or pregnancy (D13-P and...

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...
