Domestic Animal Endocrinology, 1992
The secretion of luteinizing hormone-releasing hormone (LHRH) and its temporal association with pulses of luteinizing hormone (LH) was examined in ovariectomized prepuberal gilts. Push-pull cannulae (PPC) were implanted within the anterior pituitary gland and LHRH was quantified from 10 min (200 microliters) perfusate samples.

STEROID PRIMING OF THE LUTEINIZING HORMONE RESPONSE TO LUTEINIZING HORMONE RELEASING HORMONE
Journal of Endocrinology, 1978Perifusion experiments were performed to study the stimulatory effects of luteinizing hormone releasing hormone (LH-RH) on the release of LH from anterior pituitary tissue. Exposure of pituitary tissue from normal male rats to LH-RH (5 ng/ml for 5 min) induced a small release of LH; in tissue from ovariectomized rats receiving no pretreatment, the ...

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

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.

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 ...

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 ...
