Comparative gonadotrophic potency of anterior pituitaries from cocks, laying hens and non-laying hens in molt.
A bulk of studies on the assay of gonadotrophic hormone content of the anterior pituitary from the animals in various reproductive conditions has been done. Riley and Fraps(1942b) assayed pituitary glands from chickens in various reproductive stages, judging the gonadotrophic potency by the increment of uterine weights of immature mice, and concluded that glands from non-laying hens produced a ...
متن کاملGonad-stimulating substance-like molecule from the radial nerve of the sea cucumber.
Gonad-stimulating substance-like molecule (GSSL) was isolated from the radial nerve of the sea cucumber, Apostichopus japonicus (Aj-GSSL), and its partial DNA and protein sequences were characterized. The smaller part of the molecule that also retains GSSL activity was estimated. Radial nerve extract (RNE) induced germinal vesicle breakdown (GVBD) at 3 mg/ml in 85% of immature ovarian oocytes. ...
متن کاملSelenium improves stem cell potency by stimulating the proliferation and active migration of 3T3-L1 preadipocytes.
Selenium is a trace nutrient element that protects cells against oxidative damage. In this study, the potential of selenium to improve stem cell potency through active proliferation and migration of 3T3-L1 preadipocytes was investigated, together with the underlying molecular mechanisms. The results indicated that selenium applied for 24 h stimulated cell proliferation up to 20% compared to unt...
متن کاملP-7: Association of Gonad Failure with SerumInsulin Level
Background: Serum insulin variations are occasionally observed in patients suffering infertility or gonad failure. The main purpose of the present study was to clarify the effects of gonadectomy and sex steroid hormone replacement on serum insulin level in rats. Materials and Methods: Male rats were divided into control, orchidectomized, and testosterone receiving orchidectomized animals. Femal...
متن کاملMicrovessel density and VEGF expression in pituitaries of pregnant women.
OBJECTIVE In pregnant women, the pituitary is enlarged and the prolactin (PRL) secreting cells increase in size and number. This PRL cell hyperplasia is associated with hyperprolactinemia. The aim of the present work was to investigate adenohypophysial vascularization and immunoexpression of vascular endothelial growth factor (VEGF) in pituitaries of pregnant and post-partum women and compare t...
