The effect of electrical stimulation of the ear points on the plasma ACTH and GH level in humans

The effect of electrical stimulation of the ear points on the plasma ACTH and GH level was investigated in healthy female subjects. Electrical stimulation by 20 pulses/sec for 20 min. induced an elevation of plasma GH; however, no changes were found in the plasma level of ACTH at 20 min. after the needle removal. The mechanism of action of electroacupuncture in inducing GH secretion may involve the brain endorphin, serotoninergic and catecholaminergic systems. The results obtained from the determination of ACTH suggest the conclusion that electroacupuncture did not induce stress and the increased level of GH may be due to specific effects of electrical stimulation on the neuroendocrine processes.
