Experiments were per formed in SD rats.Three pairs of bipolar electrode were implanted surgically on the antrum,ascending and descending colon of rats. The stress model was induced by restraintcold immersion (4℃ Water, 30-40 min.). The modulating effect of Zusanli ST36 acupuncture on gastroenteric electric activity was investigated. The inhibitory effects of gastro-colon electric activity were obviously displayed in stress rats, such as the frequency and amplitude of slow wave were reduced,rhythmic disorder, degree of dispersion was enlarged, fast wave was decreased and the IDMEC phase Ⅲ was prolonged or disturbed. Acupuncture of Zusanli could effectively reduce the inhibition effect of gastro-colon efortric activity induced by stress in rats.
