Beta-endorphin in pregnancy

European Journal of Obstetrics & Gynecology and Reproductive Biology, 1984
Concentrations of maternal plasma beta-endorphin (beta-EP) as measured by radioimmunoassay decline during pregnancy, reaching a nadir during the second trimester, rise during labor, remain elevated during the early postpartum period and are increased prior to elective cesarean section in the absence of labor.

Beta-endorphin-(1–27) antagonizes beta-endorphin-induced hypothermia in mice

Peptides, 1987
The effects of beta-endorphin and beta-endorphin-(1-27) on the body temperature of mice was studied at an ambient temperature of 10 degrees C. Intracerebroventricular injection of beta-endorphin (0.25-4 micrograms) and beta-endorphin-(1-27) (0.61 to 10 micrograms) caused a dose-related hypothermia. The duration of hypothermia induced by beta-endorphin-(

Pancreatic Beta-Endorphin-Like Polypeptides

Pharmacology, 1981
Acid extracts of porcine pancreas acetone powders (but not of other tissues) have been shown to contain material which will react firstly in a radioimmunoassay for beta-endorphin, and secondly, compete with 3H-Naloxone and 3H-enkephalinamide in the radio-receptor assay.

Beta Endorphin Concentrations in Human Milk

Journal of Pediatric Gastroenterology and Nutrition, 2001
ABSTRACTBackgroundThe source and regulatory mechanisms that elevate beta‐endorphin (β‐EP) approximately twofold higher than circulating plasma levels in the colostrum of lactating mothers are still unknown, and no studies have examined β‐EP availability previously during maturation phases of human milk. Therefore, the aim of this study was to determine

Plasma immunoreactive beta-endorphin in bulimics

Psychological Medicine, 1986
SynopsisThe plasma beta-endorphin response to glucose ingestion was compared in 8 bulimics and 8 controls. The bulimics demonstrated a sustained elevation of plasma beta-endorphin unrelated to glucose ingestion throughout the 5-hour study period. It is hypothesized that such an elevation of beta-endorphin is the result of stress and that it may play an
