[Acupuncture and adrenergic mechanisms of the autonomous nervous system]

A review of current knowledge about the involvement of peripheral adrenergic mechanisms in the action of acupuncture is presented. Apart from its undeniable effects on these mechanisms, acupuncture seems to operate in two different ways: indirect stimulation due to an aspecific response to the stress of the acupuncture and direct stimulation or depression, mainly of noradrenaline increase according to the placing of the needles and the condition being treated. During electroacupuncture anesthesia the inhibition of peripheral adrenergic mechanisms is proportional to the effectiveness of the induction.
