The Preparation and Properties of Equine Pituitary Gonadotropin

Journal of the American Pharmaceutical Association (Scientific ed.), 1950
A method is described for the alkaline extraction of equine pituitary glands which produced gonadotropic hormone, containing only traces of foreign protein but which was contaminated with posterior pituitary extract. Equine pituitary gonadotropin was found to possess a lower potency than that of serum gonadotropin.

STUDIES ON THE STABILITY OF EQUINE GONADOTROPIN IN CRUDE AND IN PURIFIED FORM

The Journal of Clinical Endocrinology & Metabolism, 1950
IN STUDYING the biologic and chemical properties of equine gonadotropin, a factor of immediate concern is the stability of the hormone under varying conditions. Furthermore, for clinical purposes, it is desirable that the hormone be highly purified.

Clinical evaluation of equine gonadotropin

American Journal of Obstetrics and Gynecology, 1942
Abstract 1. 1. The effect of the pregnant mare's serum hormone in the form of “gonadogen” has been studied in 83 cases in the past three years. 2. 2. In 16 patients with secondary amenorrhea, treated from one to nineteen months, 12 menstruated and 2 were refractory after nine and twelve months of continuous treatment. In the 12 who had cyclic

Enzyme Immunoassay (EIA) for Equine Chorionic Gonadotropin / Pregnant Mare Serum Gonadotropin (eCG/PMSG)

Journal of Immunoassay, 1992
A simple, accurate, sensitive enzyme immunoassay (EIA) has been developed that permits the measurement of equine Chorionic Gonadotropin activity in pregnant mare plasmas or serums as well as in commercial and highly-purified preparations. This assay is specific for eCG and eLH which share the same polypeptide structure but differ in their ...

Effects of equine chorionic gonadotropin on reproductive performance in anestrous mink

Journal of Animal Science, 1992
The incidence of anestrous mink during the normal breeding season has been reported to be as high as 5%. We sought to induce estrus in these mink by using various doses of equine chorionic gonadotropin (eCG) and human chorionic gonadotropin (hCG). Seventy-five female mink maintained under standard ranch conditions failed to demonstrate estrus during ...

Effects of the dam on equine chorionic gonadotropin concentrations during pregnancy

Domestic Animal Endocrinology, 1990
Breeding trials were designed to determine the influence of the mare on serum concentrations of equine chorionic gonadotropin (eCG) from Day 39 to Day 104 of gestation. Sires were ranked according to mean eCG concentrations found in the groups of randomly selected mares to which they were mated in 1983.

Ovulation Rates of Beef Cows and Heifers Treated with Equine Gonadotropin (PMS) and Chorionic Gonadotropin (HCG)

Journal of Animal Science, 1971
To determine the effect of gonadotropins on the ovulation rate in cows and heifers 55 beef cows and 80 beef heifers were treated with 2 subcutaneous injections of equine gonadotropin (PMS) on Days 5 and 17 of the estrous cycle and 1 intravenous injection of human chorionic gonadotropin (HCG) on the day of estrus or on Day 3 following the second PMS ...

Use of Equine Chorionic Gonadotropin to Control Reproduction of the Dairy Cow: A Review

Reproduction in Domestic Animals, 2014
ContentsEquine chorionic gonadotropin (eCG) is a member of the glycoprotein family of hormones along with LH, FSH and thyroid‐stimulating hormone. In non‐equid species, eCG shows high LH‐ and FSH‐like activities and has a high affinity for both FSH and LH receptors in the ovaries.

The Use of Equine Follicle Stimulating Hormone to Increase Equine Chorionic Gonadotropin in the Pregnant Mare

Journal of Equine Veterinary Science, 2014
Equine chorionic gonadotropin (eCG), obtained from pregnant mares, is used for assisted reproductive technologies in laboratory rodents and livestock. The objective of the present study was to use equine follicle-stimulating hormone (eFSH) to increase the incidence of twin pregnancies, through multiple ovulations, and increase eCG.

Some observations on the gynecic employment of equine gonadotropins

American Journal of Obstetrics and Gynecology, 1941
Abstract 1. 1. Equine gonadotropins may stimulate ovaries which possess normal sensitivity to pituitary stimuli. 2. 2. Equine gonadotropins are of value therapeutically in those women whose ovarian failure is due to deficient pituitary function. 3. 3.
