Degradation of [3H]beta-endorphin in rat plasma is increased with chronic stress.
With a number of acute stressors beta-endorphin is released into plasma. It is unclear if beta-endorphin is converted into any other biologically active products, nor is it clear if the rate or pathways of degradation are changed during chronic stress. To explore these issues, we incubated [3H]beta-endorphin h labeled in positions 1 and 27 with plasma from normal and chronically footshocked rat...
متن کاملPresence of immunoreactive beta-endorphin in normal human plasma: a concomitant release of beta-endorphin with adrenocorticotropin after metyrapone administration.
To elucidate whether or not beta-endorphin exists in plasma of normal subjects, plasma extracts obtained before and after metyrapone administration were subjected to gel exclusion chromatography, and fractions obtained were assayed by a sensitive radioimmunoassay for beta-endorphin. The basal plasma level of beta-endorphin was 5.8 +/- 1.1 pg/ml (mean +/- SE, n = 5), which rose significantly to ...
متن کاملBeta-endorphin concentration after administration of sucrose in preterm infants.
BACKGROUND Sucrose is an effective analgesic for procedural pain in preterm infants. It has been hypothesized that its analgesic effects are mediated by the release of endogenous opioid neurotransmitters such as beta-endorphin. OBJECTIVE To determine whether intraoral administration of sucrose was associated with an increase in serum beta-endorphin concentrations in preterm infants with a ges...
متن کاملClassification of alcoholics on the basis of plasma beta-endorphin concentration.
Recent findings suggest that a genetic deficit in opioid may be a biological marker of alcoholism. In other words, decreased plasma concentrations of opioids may be a predisposing factor, rather than a consequence, of alcohol consumption. We attempted to classify 88 randomly chosen individuals as alcoholics or nonalcoholics on the basis of plasma concentration of beta-endorphins. This criterion...
متن کاملBeta-endorphin in serum and seminal plasma in infertile men.
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)...
