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 کاملLuteinizing Hormone in Controlled Ovarian Stimulation
The role of follicle stimulating hormone (FSH) in assisted repro ductive technology is well understood, though there is still no published consensus on the need for exogenous luteinizing hormone (LH) in controlled ovarian stimulation. There is a dilemma regarding the usefulness of LH supplementation in controlled ovarian stimulation despite growing understanding of the LH and FSH interrelation...
متن کاملEquine luteinizing hormone possesses follicle-stimulating hormone activity in hypophysectomized female rats.
The ability of equine luteinizing hormone (eLH) to promote follicular growth and maturation in hypophysectomized rats has been assessed. A single injection of equine LH has been shown to promote the growth of a large number of antral and preovulatory follicles. In addition, equine LH markedly increased serum estrogen levels and uterine weight. Furthermore, equine LH, like equine chorionic gonad...
متن کاملChemosensory Stimulation of Luteinizing Hormone (LH)
22 Male Siberian hamsters (Phodopus sungorus) housed in long days (LD), but not short 23 days (SD) release luteinizing hormone (LH) when exposed to females. This study examined 24 whether this response is specific to a female and identifies the source of a stimulus that induces 25 LH release. Serum concentrations of LH, testosterone (T), follicle stimulating hormone (FSH), 26 and cortisol were ...
متن کاملEvidence for growth hormone/insulin-like growth factor I axis regulation of seawater acclimation in the euryhaline teleost Fundulus heteroclitus.
The ability of ovine growth hormone (oGH), recombinant bovine insulin-like growth factor I (rbIGF-I), recombinant human insulin-like growth factor II (rhIGF-II), and bovine insulin to increase hypoosmoregulatory capacity in the euryhaline teleost Fundulus heteroclitus was examined. Fish acclimated to brackish water (BW, 10 ppt salinity, 320 mOsm/kg H2O) were injected with a single dose of hormo...
