Relationship between release of beta-endorphin, cortisol, and trauma severity in children with blunt torso and extremity trauma

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…

Pain reactivity and plasma beta-endorphin in children and adolescents with autistic disorder

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…

Beta-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…

Cytokine and hormone profiles in mice subjected to handling combined with rectal temperature measurement stress and handling only stress

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…

Beta-endorphin levels of children in acute stress

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…

Plasma beta-endorphin during clinical and experimental ischaemic pain

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…

Plasma beta-endorphin during fasting in man

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…

T-lymphocyte cholecystokinin-8 and beta-endorphin concentrations in eating disorders: I. Anorexia nervosa

Baseline concentrations of cholecystokinin-8 (CCK-8) and beta-endorphin (beta-EP) were measured in T-lymphocytes from 33 restricting patients with anorexia nervosa (AN-R), 23 binging/purging patients with anorexia nervosa (AN-BP), and 24 healthy…

T-lymphocyte concentrations of cholecystokinin-8 and beta-endorphin in eating disorders: II. Bulimia nervosa

Concentrations of cholecystokinin-8 (CCK-8) and beta-endorphin (beta-EP) in T-lymphocytes of 26 women with bulimia nervosa (BN) and in 26 age- and sex-matched healthy comparison subjects were measured. Ten patients were then treated with 300 mg/day…

Age-related changes of beta-endorphin and cholecystokinin in human and rat mononuclear cells

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…

Beta-endorphin concentrations in the peripheral blood mononuclear cells of migraine and tension-type headache patients

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…

Beta-endorphin levels are reduced in peripheral blood mononuclear cells of cluster headache patients

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…

Hormonal response to surgical stress in schoolchildren

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…

Opioid peptide-expressing leukocytes: identification, recruitment, and simultaneously increasing inhibition of inflammatory pain

BACKGROUND: Inflammatory pain can be effectively controlled by an interaction of opioid receptors on peripheral sensory nerve terminals with opioid peptides released from immune cells upon stressful stimulation. To define the source of opioid peptide…
