What's more, mice seemed to get hooked on the high levels of beta-endorphin
. After getting regular doses of UV light, mice showed signs of withdrawal when their endorphins were silenced with naloxone: The animals' paws trembled, their teeth chattered and they shook like wet dogs.

It stimulates the release of beta-endorphin
and adrenocorticotropin hormone (ACTH).
Experimental pain thresholds and plasma beta-endorphin
levels during exercise.
 examined behavioural and physiological pain responses, plasma beta-endorphin
levels and their relationship in 73 children and adolescents with autism and 115 normal individuals matched for age, sex, and pubertal stage during blood drawing.
and ACTH in plasma: effects of physical and psychological stress.
and HGH increase are associated with both the anticipation and experience of mirthful laughter.
The following hormones and chemicals have been shown to initiate parturition and facilitate sexual function: oxytocin, catecholamines, beta-endorphin
, and prostaglandins (Cunningham et al., 2010c).
However, studies with naloxone have suggested that beta-endorphin
may have an important role to play in steroidogenesis and may have a role in regulating transport of luminal material1.
RESULTS: Acute psychological stress induced subjective distress, increases of circulating concentrations of epinephrine, norepinephrine, beta-endorphin
, adrenocorticotropic hormone (ACTH), and cortisol, and a selective redistribution of natural killer (NK) cells into the peripheral blood as compared with the video control condition.
Inhibition of acid secretion by electrical acupuncture is mediated via beta-endorphin
, a product derived from a pro-opiomelanocortin (POMC) precursor, is involved in regulating reproductive function as one of main inhibitory factors in mammals (Kalra and Kalra, 1986), rodents (Gruenewald and Matsumoto, 1991) and birds (Stansfield and Cunningham, 1987).
