PURPOSE: To determine the levels of beta-endorphin and cortisol in children with multiple injuries and to determine whether there is any difference between and compare the severity of trauma and beta-endorphin and cortisol release as calculated using…

BACKGROUND: Reports of reduced pain sensitivity in autism have prompted opioid theories of autism and have practical care ramifications. Our objective was to examine behavioral and physiological pain responses, plasma beta-endorphin levels and their…

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…

Stress is known to either up or down regulate immunity. In this study, mice were subjected to handling combined with rectal temperature measurement (RTM) stress or handling only stress. We investigated whether there were any significant differences…

In this study aiming to clarify the relationships between beta-endorphin and glucose levels, beta-endorphin levels were determined in children in acute stress. The study was carried out on 32 critically ill children between 5 days and 12 years…

An improved radio-immunoassay using an antiserum directed towards the N-terminal part of the endogenous opioid peptide beta-endorphin 1-31 (beta-EP) was validated and applied to a study of beta-EP in plasma during ischaemic pain. Experimental…

To identify the effects of acute starvation on endogenous opioids in man, plasma beta-endorphin (beta-EP) was measured in 17 patients before, during and after fasting. Patients were assigned a posteriori into two groups: group A, comprised of 11…

Beta-endorphin (BE) and cholecystokinin (CCK) were measured in fresh PBMC isolated from human subjects and rats. The BE and CCK PBMC contents increased significantly with age both in human and rat models. Moreover, polyclonal stimulation induced a…

Levels of beta-endorphin in peripheral blood mononuclear cells have been studied as a new approach to investigating opioid tone in migraine and tension-type headache. Sixty-one patients with migraine without aura, 39 with migraine with aura and 23…

Opioid system hypofunction has been postulated in cluster headache (CH) on the basis of reduced opioid levels found in the cerebrospinal fluid (CSF). In this study beta-endorphin levels were monitored in the peripheral blood mononuclear cells of 65…

PURPOSE: To determine hormone concentrations (ACTH, cortisol, beta-endorphin) in children before and after surgery, to assess the correlation between any hormonal changes and to study the influence exercised on them by the severity of surgical stress…

Serum beta-endorphin was quantified by radioimmunoassay in 71 patients with psoriasis vulgaris, other chronic inflammatory skin diseases with T-cell infiltrates [atopic dermatitis (n = 25), and systemic sclerosis (n = 34)], and 100 healthy subjects.…

Physiological, plasma beta-endorphin and cortisol responses to nasotracheal intubation were studied in 20 distressed infants of median age 0.3 days (range 0.1-23 days) randomized into groups given pethidine 1 mg/kg (n = 10) or alfentanil 20…

beta-Endorphin (beta-EP) and cholecystokinin 8 (CCK-8) concentrations in peripheral blood mononuclear cells were measured in 12 drug-free autistic (AU) children, in 10 drug-free children with pervasive developmental disorders (PDD) and in 11 healthy…
