... of the median eminence area (MEA) were incubated in vitro and LHRH release in response to the combined actions of copper and prostaglandin E 2 was used as a criterion for secretory function. Based on vaginal cytology, young (2–3 months) females exhibited regular estrous cycles, the transition to irregular...

...Dean G. Karahalios; Jon E. Levine The effects of an opiate receptor antagonist, naloxone, on the in vivo release of luteinizing hormone releasing hormone (LHRH) in ovariectomized and intact female rats were examined using push-pull perfusion. Hypothalamic LHRH release rates were determined before...

...Miriam Colombani-Vidal; Ayalia Barnea Copper, complexed to histidine (CuHis), stimulates LHRH release from explants of the median eminence area (MEA). To gain further understanding of the mechanism of copper action, in this study, we assessed the Na + and energy requirements for CuHis stimulation...

...Miriam Colombani-Vidal; Ayalia Barnea We have previously shown that chelated copper stimulates LHRH release from explants of the median eminence area (MEA). Characteristics of this release process are: ligand and metal specificity, the involvement of a limited number of copper interactive sites...

... the mechanism of action of copper, we addressed two questions: (a) What is the divalent metal [metal(II)] specificity for this release process? (b) Is the stimulation of LHRH release by CuHis dependent on influx of extracellular calcium? MEA obtained from adult male rats were incubated for 15 min with one...

... by radioimmunoassay. The spontaneous release rate of LHRH was maximal from MBH of 12-day-old rats and minimal from those of 32 days. Depolarization of neural membranes, by medium containing 45 mM K + induced a stimulation of LHRH release. This K + -induced release of LHRH was also most prominent on day 12...
