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...

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...

Concerted actions of ovarian steroids and prostaglandin F₂a on smooth muscle contractility of ovine and bovine uterine arteries

Creator:: Ford, Stephen Paul
Abstract:: The role of estradiol- 17β, progesterone and prostaglandin F₂α (PGF₂α) in altering contractility of uterine vascular smooth muscle was investigated. A segment of uterine artery (3. 5 cm) supplying each uterine horn of ewes and heifers were removed at necropsy and perfused with oxygenated Krebs Henseleit Solution prior to initiating...

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...

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...

The response of the bovine infundibulum to norepinephrine and acetylcholine during estrogen and progesterone dominance

Creator:: Friedman, Ron
Abstract:: A local effect of endogenous ovarian hormones on the in vitro responses of the bovine infundibulum to the neurotransmitters norepinephrine (NE) and acetylcholine (Ach) was investigated. Prostaglandin F₂α-tham salt was utilized to induce luteal regression in six heifers which were necropsied during proestrus. Six heifers were also necropsied during the...

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...
