In our previous study, we showed that irradiation, by low power laser, of the stellate ganglion of patients suffering from facial pain, trigeminal neuralgia, and facial palsy had an ameliorative effect. The method is safer than injecting anesthetics. However, basic research on the mechanism of this treatment procedure is not numerous. In this study, the author examined the validity of two hypotheses explaining the physiological phenomena F Itin. 1. ffoni laser irradiation., namely the nerve block-like effect hypothesis and the acupuncture-like effect hypothesis. The stellate ganglions of 15 healthy subjects were irradiated with low power Nd: V AG laser (300 mW), and the following were examined:<BR>1) Changes in temperature of the skin of the face and hand dorsum.<BR>2) Pulse rate and blood pressure.<BR>3) Plasma catecholamin (adrenaline and noradrenaline).<BR>4) Peripheral autonomic surface potential (PASP).<BR>Tin results were as follows.<BR>1) Although only one stele was irradiated, the skin temperature rose on both sides of the face and hand dorsum.<BR>2) systolic pressure fell significantly in the irradiated group.<BR>3) The noradrenalme level became lower at 15 minutes-irradiation in the irradiated group.<BR>4) The PASPs did not show significant change either in latency or amplitude.<BR>It is concluded that the effects of irradiation occur reflectively through the central nervous system, by lowering the tension of the sympathetic nervous system.
