Abstract
A seminar was held with “the development of research on auricular acupuncture” as the main theme. In this seminar, the recent development of auricular acupuncture in Japan and abroad, its action mechanism, and clinical effects were reviewed, and the findings were comprehensively evaluated.
Concerning basic research on the effects of auricular acupuncture on obesity, the relationship between the auricle and hypothalamo-autonomic system and individual variation associated with differences in the condition of patients receiving the treatment were reported. As for the action mechanism, leptin expressed in white adi-pose tissue (WAT) due to acupuncture stimulation of the auricle was reported to bind to leptin receptors (Ob-R) in both peripheries and the center and suppress food intake.
Concerning clinical effects of auricular acupuncture, the results reported in Japan indicating its effectiveness for the treatment of obesity were presented. However, no overall conclusion was reached, because papers published abroad were not consistent in the therapeutic procedure or evaluation parameters. Auricular acupuncture appeared to be clinically effective for analgesia and the treatment of drug addiction but ineffective as an anti-smoking treatment.
