摘　　要：在束缚-冷大鼠的应激模型上，研究了电针足三里穴对胃肠电活动的调整效应。应激大鼠的胃结肠电活动呈现明显的抑制效应，包括慢波波幅下降、频率降低、节律率乱、离散度大、快波减少，在肠电相当于消化间期综合肌电Ⅲ相的出现周期延长或消失破坏。电针组胃肠电活动的应激性变化明显减轻。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.
