Hypothalamic KiSS1/GPR54 Gene Expressions and Luteinizing Hormone Plasma Secretion in Morphine Treated Male Rats
Objective The inhibitory effects of Morphine and the stimulatory influence of kisspeptin signaling have been demonstrated on GnRH/LH release. Hypothalamic kisspeptin is involved in relaying the environmental and metabolic information to reproductive axis. In the present study the role of kisspeptin/GPR54 signaling system was investigated on relaying the inhibitory effects of morphine on LH horm...
متن کاملRadioimmunoassay for luteinizing hormone releasing hormone in plasma.
A sensitive and specific double antibody radioimmunoassay has been developed capable of measuring LH-RH in extracted human plasma. Thyrotropin releasing hormone, lysine vasopressin and most of LH-RH analogues did not appear to affect the assay. Hypothalamic extract and some of the LH-RH analogues produced displacement curves which were parallel to that obtained with the synthetic LH-RH. Sensiti...
متن کاملKisspeptin receptor agonist (FTM080) increased plasma concentrations of luteinizing hormone in anestrous ewes
Kisspeptin receptor (KISS1R) agonists with increased half-life and similar efficacy to kisspeptin in vitro may provide beneficial applications in breeding management of many species. However, many of these agonists have not been tested in vivo. These studies were designed to test and compare the effects of a KISS1R agonist (FTM080) and kisspeptin on luteinizing hormone (LH) in vivo. In experime...
متن کاملEffect of castration on plasma luteinizing hormone concentrations in prepubertal boars.
Mean concentrations and the occurrence of pulsatile release of luteinizing hormone (LH) were determined in 14-wk-old crossbred boars (50.5 +/- 1.5 kg) after bilateral or unilateral castration at 10 wk of age. Blood was collected at 10-min intervals for 5 h. Then gonadotropin releasing hormone (GnRH; 40 micrograms) was given and sampling was continued at 5-min intervals for 1 h. Compared with in...
متن کاملLuteinizing Hormone Concentrations in of Postpartum Beef Cows Injected Microencapsulated Luteinizing Hormone-releasing Hormone Analog 1 Serum With
Twenty-five cows were divided equally into five groups to determine whether [D-Trp6]luteinizing hormone releasing hormone (LHRH-A) microencapsulated in poly (DL-lactide co-glycolide) would increase basal serum concentrations of LH during the postpartum period. On d 5 postpartum, cows were injected i.m. with 2 ml of vehicle alone (Group 1) or vehicle containing microcapsules calculated to releas...
