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...

Factors affecting prolactin secretion in the African elephant

Creator:: Bechert, Ursula S.
Abstract:: Prolactin (PRL) is a peptide hormone that is involved in a number of diverse physiologic roles, particularly with respect to reproduction, including: influencing sexual and parental behaviors, onset of puberty, regulation of seasonal reproduction, follicular maturation, ovulation, luteinization and corpus luteum (CL) function, steroidogenesis, mammary gland development and lactation, testicular...

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...

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...

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...

Intrauterine migration of the porcine embryo

Creator:: Pope, William Frederick
Abstract:: The mechanism(s) involved with intrauterine migration of the porcine embryo was investigated. Twenty-four gilts on Days 6, 9 and 12 of gestation (Day 0 = 1st day of estrus) were utilized to examine the relationship between myometrial activity and intrauterine migration. On Day 2, embryos were flushed from one oviduct...

Some aspects of the mechanism of estrogen action in the uterus of the ewe

Creator:: Koligian, Karl Bruce
Abstract:: The binding of estrogen to endometrium and uterine arteries of the ewe was investigated by use of a [³H]estradiol exchange assay and by incubating whole tissue aliquants with [³ H]estradiol, a method which permits quantification of bound estrogen translocated from the cytoplasm to the nucleus. Five ewes were necropsied on...

Pituitary and uterine control of ovarian function in the gilt and ewe

Creator:: Chakraborty, Prabir Kumar, 1936-
Abstract:: The role of the pituitary gland and uterus in regulating ovarian function in the estradiol-treated gilt and ewe was investigated in two experiments. Pituitary gonadotropin content, ovarian follicular development and corpus luteum function were studied following daily intramuscular injection of seven gilts with 7 mg of 17β-estradiol from day 11...
