Electroacupuncture is the combined treatment of mechanical and electric stimuli on the needle head, on which electricity runs after acupuncturing at the acupuncture points. It is reported that its treatment effect depends on the parameter of stimulus, which is wave of stimulus, frequency, voltage, and duration of electric current. To get the effective treatment, stimulus intensity over threshold is needed. We planned to experiment whether acupuncture effect is affected by sex, age, and weight. After we conducted electric stimulus at Zusanli(ST 36) which is known to increase small intestinal motility in normal rats, we observed the effects and got the following results. Though the increased effects of small intestinal motility of electro-acupuncture at Zusanli(ST 36) did not show the difference of sex, this effect was observed to have a tendency to decrease according to weight increase without distinction of sex. But the effect of electro-acupuncture shown in 4, 5, 7 weeks old without distinction of sex was observed to have a tendency to decrease with the growing of weeks-old in the male rat group. And the significant change without specific tendency was observed in the 4, 5 weeks old female rat group. This result suggested that sex, weight, and age should be considered to get the efficient electro-acupuncture. The more experimental study should be advanced to investigate the correlation between the factors that can affect the acupuncture treatment, and, afterward, the interconnection into the clinical use.
