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-(

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

Effects of Pituitary Beta-Endorphin Secretagogues on the Concentration of Beta-Endorphin in Rat Cerebrospinal Fluid: Evidence for a Role of Vasopressin in the Regulation of Brain Beta-Endorphin Release

Neuroendocrinology, 1990
The concentration of beta-endorphin-immunoreactivity (beta E-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 beta E and other pro-opiomelanocortin (POMC)-derived peptides at the level of the anterior and ...

Prolactin response to beta-endorphin in man

Life Sciences, 1980
Abstract Beta endorphin was administered intravenously to six medication-free schizophrenic patients under placebo-controlled conditions. Serum prolactin (PRL) and growth hormone (GH) concentrations were measured for 90 minutes after infusion. Prolactin was significantly increased following beta-endorphin infusion compared to placebo infusions ...

The complete sequence of sheep beta-endorphin

Biochemical and Biophysical Research Communications, 1977
Abstract Automatic sequencing of an isothiocyano naphthalene sulfonic acid derivative of sheep beta-endorphin, allowed the positioning of 24 out of 31 residues. Peptide mapping of a tryptic digest of the native molecule permitted the filling of remaining gaps.

Pharmacologic Studies of Beta-Endorphin in Psychopathology

Psychiatric Clinics of North America, 1983
The pharmacologic trials of beta-endorphin in the field of mental illness are critically reviewed in this article, with an emphasis on the therapeutic efficacy of beta-endorphin in schizophrenia and affective disorders.

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.

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

Human EEG response to beta-endorphin

Psychiatry Research, 1979
Beta-endorphin, morphine, and saline were given intravenously to a single schizophrenic subject on separate occasions in a double-blind design. EEG spectral analyses performed on data collected before and after drug injection demonstrated that beta-endorphin and morphine produced similar increases in alpha power within 5 to 15 minutes after injection ...
