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, 1987The 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-(

Beta Endorphin Concentrations in Human Milk
Journal of Pediatric Gastroenterology and Nutrition, 2001ABSTRACTBackgroundThe 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

The role of endorphins in animal learning and behavior
Neuroscience and Biobehavioral Reviews, 1980 The present review examined the influence of endorphins in animal learning and behavior. It was suggested that in learning paradigms involving stress, the stressor elicits the release of endorphins.

Beta-endorphins in acute myocardial infarction [PDF]
Clinical Cardiology, 1986 AbstractThe endogenous peptide B‐endorphin (B‐EP) is closely connected with different aspects of homeostasis, behavior, and in particular with the perception of pain. The purpose of this study was to investigate the correlation between: (a) the level of plasma B‐EP and the intensity of pain in acute myocardial infarction (AMI); and (b) the B‐EP and ...

The concentration of β-endorphin-immunoreactivity (βE-IR) in cerebrospinal fluid (CSF) and plasma of rats was determined following intracerebroventricular (ICV) treatment of conscious animals with substances known to stimulate the release of βE and other pro-opiomelanocortin (POMC)-derived peptides at the level of the anterior and intermediate lobes of

Pancreatic Beta-Endorphin-Like Polypeptides
Pharmacology, 2008Acid 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.

Dexamethasone suppresses beta-endorphin in humans
Psychoneuroendocrinology, 1985Studies assessing the effect of glucocorticoids on beta-endorphin regulation in man have yielded inconsistent results. As measured by a highly specific beta-endorphin assay procedure, plasma immunoreactive beta-endorphin (irB-EP) in six healthy subjects was significantly suppressed, along with cortisol, after a 2 mg oral dose of dexamethasone (DEX ...

Plasma immunoreactive beta-endorphin in bulimics
Psychological Medicine, 1986SynopsisThe 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
