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 and adrenocorticotropin are selected concomitantly by the pituitary gland.
Science, 1977The opiate-like peptide beta-endorphin and adrenocorticotropin are concomitantly secreted in increased amounts by the adenohypophysis in response to acute stress or long-term adrenalectomy as well as in vitro in response to purified corticotropin ...

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-endorphins in essential blepharospasm
Neuro-Ophthalmology, 1994The effect of the administration of adrenergic and serotoninergic substances on beta-endorphins was evaluated in four patients with essential blepharospasm. The lack of beta-endorphin release following administration of adrenergic agents demonstrated that this aminergic action on the hypothalamus-pituitary adrenal axis is modified in the presence of ...

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

A 41-residue peptide purified as a corticotropin-releasing factor/beta-endorphin-releasing factor (CRF) in vitro was tested for its ability to stimulate the secretion of ACTH, beta-endorphin, and corticosterone in three animal groups: 1) unanesthesized ...

The complete sequence of sheep beta-endorphin
Biochemical and Biophysical Research Communications, 1977Abstract 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.

beta-Endorphin is associated with overeating in genetically obese mice (ob/ob) and rats (fa/fa).
Science, 1978Small doses of the opiate antagonist naloxone selectively abolished overeating in genetically obese mice (ob/ob) and rats (fa/fa). Elevated concentrations of the naturally occurring opiate beta-endorphin were found in the pituitaries of both obese ...

Prolactin response to beta-endorphin in man
Life Sciences, 1980Abstract 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 ...
