逐点动态刺激足阳明经对大鼠胃粘膜损伤保护作用的实验观察

以无水乙醇灌胃造成大鼠胃粘膜损伤模型，以经络疏通仪沿大鼠体表“足阳明经”胸、腹段作逐点动态刺激，与非针刺组比较，大鼠胃粘膜损伤指数低，胃排空率升高，说明针刺“足阳明经”对大鼠胃粘膜有一定保护作用。毁损大鼠脊髓后再刺激大鼠足阳明经，与毁损前比较仍能使大鼠胃粘膜损伤指数降低，但降低幅度及胃排空率升高幅度均较毁损前低。说明毁损大鼠脊髓并不完全取消针刺胃经对大鼠胃粘膜保护作用，刺激足阳明经与胃的相关联系不能完全用神经节段学说解释。

EXPERIMENTAL OBSERVATION ON PROTECTIVE EFFECT OF DYNAMIC EXCITING ON EVERY POINTS IN FOOT YANGMING CHANNEL ON GASTRIC MUCOSA OF RAT

Filling stomach with ethanol without water modeled a injured gastric mucosa of rat.The every points along the chest and abdomen section of Foot-yangming Channel in the body surface of rat were dynamically stimulated one by one with channel dredge instrument.The damage index of gastric mucosa was lowered and the evacuation rate of stomach was increased as compared with the non stimulating group.The result shows that needling Foot-Yangming channel has a protective effect on the gastric mucosa of rat.Stimulating Foot-Yangming channel of rat once again after damaging the spinal cord of rat still lowered the damage index compared with the index before damaging,but the lowered range and the increased range of stomach evacuation rate were lower than that before damage.Such a result explains that impairing the spinal cord of rat con not completely deprive needling St.of protecting effects on gastric mucosa of rat.The relationship between stimulatin St.and stomach is not completely explained by nerve section theory.
