Neuroblastoma x glioma hybrid cells (NG108CC15) were examined for the presence of ?-endorphin-like material. In order to differentiate this ?-endorphin-like material from crude cell extract, a procedure for immunoaffinity chromatography was developed. The monoclonal antibody 3-E7 employed possesses the unique property of recognizing the N-terminal sequence of virtually all endogenous opioid pep...

Endorphin is a hormone and types of endorphins are found in our body. Endorphin is like morphine in structure and effects and has same binding site in the brain cells or receptors. Different endorphins are released during different exercises or eating food or during sex, meditation etc. Anxiety is a disease which is widely spread and can be treated with this endogenous endorphin without using a...

Proopiomelanocortin (POMC) is expressed in pituitary, central nervous system, and in a few peripheral tissues. This study addresses the hypothesis that metabolic stressors, such as acidosis, may induce the release of POMC derivatives into the cardiovascular system not only from the pituitary but also from other sites of POMC expression. In our study, we investigated the liberation of POMC deriv...

beta-Endorphin blocks release of luteinizing hormone (LH)-releasing hormone (LHRH) into the hypophyseal portal vessels by stimulating mu-opiate receptors, thereby inhibiting secretion of LH. LHRH release is controlled by release of nitric oxide from nitricoxidergic (NOergic) neurons in the basal tuberal hypothalamus. To determine whether beta-endorphin exerts its inhibitory action on this NOerg...

BACKGROUND In animal models of circulatory shock and heart failure concentrations of the endogenous opioid peptide beta endorphin are raised and opioid receptor blockade improves haemodynamic variables and survival. This study was performed to identify whether acute myocardial ischaemia provokes the release of beta endorphin in humans. METHODS Observational study in a university cardiology ce...

AIM To access beta-endorphin levels in serum as well as seminal plasma in different infertile male groups. METHODS Beta-endorphin was estimated in the serum and seminal plasma by enzyme-linked immunosorbent assay (ELISA) method in 80 infertile men equally divided into four groups: non-obstructive azoospermia (NOA), obstructive azoospermia (OA), congenital bilateral absent vas deferens (CBVAD)...

The paraventricular hypothalamus regulates autonomic nerve outflow and is innervated with /3-endorphin-immunoreactlve nerve terminals. This study examined the effects of /3-endorphin microinjected into the paraventricular hypothalamus on blood pressure, heart rate, and plasma catecholamine and glucose concentrations in conscious, unrestrained spontaneously hypertensive rats (SHR) and Wistar-Kyo...

a-Neo-endorphin anddynorphin immunoreactivities in rat brain were visualized by double antibody immunofluorescence of frozen sections. Antibodies were used that were specific for their respective antigens. The pattern of neuronal immunostaining produced by a-neo-endorphin and dynorphin antisera in adjacent serial sections was completely superimposible. No areas were found in which a-neo-endorph...

An effect of metrizamide, a contrast medium, on results of beta-endorphin radioimmunoassay was examined. We found that 1, 5, and 10 microL of the medium added to 100 microL of standard containing 0 to 500 pg of beta-endorphin shifted the standard curve to the left in proportion to the metrizamide concentration. Three other contrast media showed a similar effect at low concentrations of beta-end...

The present study was performed to investigate the effect of 0-endorphin on macrophage colony-stimulating factor (MCSF)-induced differentiation of macrophages from bone marrow cells in a semisolid culture system. 0-endorphin increased the number of macrophage colonies when bone marrow cells were cultured in the presence of M-CSF plus lipopolysaccharide (LPS). This was not the case with LPSunres...
