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, 2008
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

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.

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 ...

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

Dexamethasone suppresses beta-endorphin in humans

Psychoneuroendocrinology, 1985
Studies 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 ...

Pancreatic Beta-Endorphin-Like Polypeptides

Pharmacology, 2008
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.

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 ...

$beta;-ENDORPHIN IN HUMAN CEREBROSPINAL FLUID

The Lancet, 1978
beta-endorphin is a brain peptide with potent morphine-like activity structurally related to the anterior pituitary hormone beta-lipotrophin (beta-L.P.H.). We have developed a radioimmunoassay for human beta-endorphin in plasma and cerebrospinal fluid (C.S.F.).

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.
