Experiments were performed 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 restraint cold immersion (4 degrees C 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 electric activity induced by stress in rats.
实验在SD大鼠身上进行。通过手术将三对双极电极植入大鼠的胃窦、升结肠和降结肠。应激模型通过束缚冷浸(4℃水,30 - 40分钟)诱导产生。研究了足三里穴针刺对胃肠电活动的调节作用。应激大鼠的胃肠结肠电活动抑制作用明显表现出来,如慢波的频率和幅度降低、节律紊乱、离散度增大、快波减少以及结肠肌电综合慢波Ⅲ期延长或紊乱。针刺足三里可有效减轻应激对大鼠胃肠结肠电活动的抑制作用。
