Luteinizing Hormone-Releasing Hormone
Archives of Internal Medicine, 1986To the Editor. —In their excellent review of gonadotropin-releasing hormone (GnRH) (also known as luteinizing hormone-releasing hormone [LH-RH]) in the September 1985 issue of theArchives, Hammond and Ory 1 cite the potential advantages of GnRH over conventional gonadotropin therapy for induction of spermatogenesis as rapidity, higher success rate ...

Stereoisomers of luteinizing hormone-releasing hormone
Biochemical and Biophysical Research Communications, 1974Summary Six decapeptide analogs of the luteinizing hormone-releasing hormone (LH-RH) were prepared with the D-isomers of pyroglutamic acid, histidine, tryptophan, tyrosine, leucine, and arginine successively replacing the corresponding L-amino acids of the hormone. [D-pGlu 1 ]-LH-RH and [D-His 2 ]-LH-RH had appreciable LH-releasing activities, 8% and

Luteinizing-Hormone-Releasing Hormone
New England Journal of Medicine, 1977One of the exciting advances in endocrinology has been the discovery of a family of peptidic neurohormones in the hypothalamus that stimulate or inhibit the secretion of adenohypophysial hormones.

THERE is a demand for an easy and accurate method of assaying the luteinizing fraction of gonadotrophic hormone. The present method depends upon the formation of corpora haemorrhagica in the ovaries of immature female mice after rendering their Graafian follicles mature.

Stimulating luteinizing hormone
Drug Testing and Analysis, 2011Low molecular weight luteinizing hormone (LMWLH) receptor agonists could be of interest as a potential doping substance for athletes. These orally active compounds induce the production of endogenous hormones such as testosterone in a similar way to LH.

Radioimmunoassay of Luteinizing Hormone Releasing Hormone
Nature, 1973THE isolation and characterization of hypothalamic luteinizing hormone releasing hormone (LH–RH) and its subsequent synthesis have made possible the production of an antibody specific for this decapeptide.

The concentrations of 17-oxosteroids in the spermatic venous blood of anaesthetized dogs were used as an index of LH release to assess the effects of arginine-vasotocin on the response of the canine pituitary gland to exogenous luteinizing hormone releasing hormone (LH-RH).

Luteinizing Hormone Receptors in Luteinized Rat Ovaries
1973It has been demonstrated that radioiodinated HCG and LH are accumulated in vivo by mouse and rat ovaries (1–4). These observations suggested the existence of specific receptor sites for gonadotropic hormone in this target tissue. Recently, the existence of specific receptors for LH and HCG have been reported in slices of luteinized rat ovaries (5) and ...

Adult Soay rams with low concentrations of gonadotrophins in the circulation as a result of 12 weeks of exposure to long daylengths (16 h light: 8 h darkness) were given small doses (100 ng) of synthetic luteinizing hormone releasing hormone (LH-RH) into the jugular vein two, four or seven times/day for 10 days.

Luteinizing Hormone-Releasing Hormone
1985Luteinizing hormone-releasing hormone (LHRH), originally isolated from mammalian hypothalami, has well-established functions in mediating hypothalamic control of pituitary hormone release (Blackwell and Guillemin, 1973; Schally et al., 1973). Parvicellular hypothalamic neurons that contain LHRH project to portal vessels originating in the median ...
