Temperature changes before and after aeupuneture st aeupoints on the face, back of hands, and fingertips were observed with Thermography. 15cases of ENT patients were tested. The results showthat acupuncture induces changes in acupoint temperature. At facial acnpoints the temperature mainly rises, and at fingertip acupoints it mainly drops. There are significant differences among the various acupoints and individuals. Differences in temperature changes between facial aeupoints and fingertip acupoints, and bwtween the "all rise group" (Temperature rises at all aeupoints) and "All drop group" (Temperature drops at all acupoints) of patients are of statistical significance. It is our opinion that using Thermography to determine changes in acupoint temperature is a useful and objective means in determining the effect of acupuncture and its mechanism. The method merits further exploration.
