针刺补泻手法对家兔实验性胃节律紊乱的影响

Effects of Reinforcing and Reducing by Lifting and Thrusting in Manual Acupuncture on Experimental Gastric Dysrhythmia in Rabbit's

对空腹麻醉的家兔,经微量泵从胃左动脉匀速连续灌注肾上腺素(Adr)、乙酰胆碱(Ach)和胰高血糖素(Glucagon)建立胃节律紊乱的实验模型。结果在灌注Ach或Glucagon后,针刺补法可使胃电幅值升高,泻法可使之降低(P<0.05),都使基本电节律趋于正常;在灌注Adr后,补泻手法对胃电频率、幅值无明显差异,但基本电节律也呈规律性。切断膈下迷走神经和内脏大神经后,针刺补泻手法消失了对胃节律紊乱的调整作用。提示针刺补泻手法对胃节律紊乱有不同的效应,自主神经系统的功能状态和完整性在针刺补泻的效应中起着重要的作用。

The experimental model of gastric dy.srhythrnia could be produced by left gastric artery infusion of Adr, Ach and Glucagon at a steady vilocity in fasting and anaesthetic rabbits.The effects and mechanism of reinforcing and reducing in manual acupuncture on gastric dysrhythmia were investigated. The results showed that after infusion of Ach or glucagon reinforcing method of acupuncture may increased the amplitude of basic electric rhythm ( BER ) (P<0.05). Reducing method of acupuncture may decreased them (P<0.05). Both different manual acupun-cture may exhibit normal rhythm of BER. After infusion of Adr the effects of two manual acupuncture method on the gastric activity differed insignificantly from the control group. But the rhythm of BER could turned to approch the normal regular activity After inferior phrenicus vagotomy and splanchnic neurotomy such effects of different reinforcing and reducing method on gast'ric dysrhythmia were disappeared. It can be concluded that acupuncture effects of reinforcing and reducing method on gastric dysrhyithmia were different. The functional condition and integrity of automomic nerve system may be play, an important role in the acupuncture -effects of refbrcing and reducing method.
