内源性阿片肽包括脑啡肽、内啡肽和强啡肽等。不仅存在于中枢神经系统,而且也存在于其他组织和器官,如垂体、胃肠道和肾上腺髓质,在体内起着神经递质和调质的作用。在诸如应激、疼痛、脑内刺激、针刺等因素中,以针刺刺激所导致的阿片肽改变最为显著。内源性阿片肽在痛觉调节机制中具有重要作用,对体内激素分泌、体温调节、消化活动、睡眠、精神、运动等生理功能都有一定影响。近年来,一些学者认为脑啡肽是一种免疫调节物,内啡肽是神经内分泌系统和免疫系统之间的联系物。因此,免疫系统与
Endogenous opioid peptides include enkephalin, endorphins and dynorphin. Not only exists in the central nervous system, but also in other tissues and organs, such as the pituitary gland, gastrointestinal tract and adrenal medulla, plays a role in the body’s neurotransmitters and conditioning. In factors such as stress, pain, intracerebral stimuli, and acupuncture, opioid peptide changes caused by acupuncture stimuli are most pronounced. Endogenous opioid peptides play an important role in the mechanism of pain regulation, and have certain effects on hormone secretion, body temperature regulation, digestion, sleep, mental and physical functions. In recent years, some scholars believe that enkephalin is an immune regulator and endorphin is a link between the neuroendocrine system and the immune system. Therefore, the immune system
