Application of a Leydig cell stimulation assay to quantitate circulating levels of luteinizing hormone in the bovine, baboon and equine
(Texas A&M University. Libraries, 1978)A Leydig cell stimulation assay for luteinizing hormone was applied to the analysis of LH activity in serum samples from the baboon, the bovine, and the equine. Close parallelism was seen between dose response curves for ... -
The effect of neonatal thymectomy on gonadotropin secretion in the female rat
(Texas A&M University. Libraries, 1982)The thymoprivic condition in the neonatally thymectomized or nude female mouse is accompanied by changes in estrous cyclicity, ovarian development and gonadotropin secretion. In the present studies, the neonatally thymectonized ... -
Effect of ovariectomy and ovarian steroid replacement of patterns of plasma LH in the bovine
(Texas A&M University. Libraries, 1981)A study was designed to evaluate the pulsatile patterns of plasma LH in five mature Jersey cows on day 3 of two consecutive estrous cycles, and at different time intervals following ovariectomy (4, 42 and >59 days ... -
Ovarian and pituitary function during the post-partum interval in Brahman and Brahman crossbred cows
(Texas A&M University. Libraries, 1989)Studies were designed to determine: 1) the effect of post-partum nutritional restriction on serum luteinizing hormone (LH) concentrations and blood metabolites; 2) changes in ovarian cell type numbers, follicular populations, ... -
The role of calcium in gonadotropin releasing hormone-induced luteinizing hormone secretion from the bovine pituitary
(Texas A&M University. Libraries, 1986)The hypothesis was tested that GnRH acts to release LH by increasing calcium uptake by the gonadotroph which in turn stimulates calcium-calmodulin activity and results in LH release from bovine pituitary cells as it does ...
