针刺足阳明经穴对兔胃粘膜损伤前后胃运动功能的影响

目的 :通过针刺足阳明经穴对兔胃粘膜损伤前后胃运动的观察 ,进一步探讨足阳明经与胃的相关规律。方法 :对 40只大耳白兔运用无水乙醇灌胃 ,造成胃粘膜损伤模型 ,然后观察针刺对胃粘膜损伤前后胃运动功能的影响。结果 :胃粘膜损伤造模前后 ,胃运动振幅指数百分率比较差异有显著性意义 ,造模后振幅指数显著下降 ,与造模前比较 P <0 .0 1,针刺四白、足三里穴能增强胃运动 ,针刺后比刺前胃运动振幅指数显著升高 (P <0 .0 1) ,尤以四白穴最为显著 ,且在胃粘膜损伤后 ,同样能增强胃的运动。结论 :胃粘膜损伤后 ,胃运动振幅指数显著下降 ,针刺足阳明经穴后可使胃运动振幅指数上升 ,提示足阳明经与胃具有相关性。

Effect of Acupuncture of Foot-Yangming Meridian Points on Function of Gastric Movement before and after Gastric Mucosa Damage

Objective: To explore the relationship between meridian of Foot-Yangming and stomach by observing the influence of acupuncture of Foot-Yangming meridian points on the gastric movement before and after gastric mucosa damage in the rabbits. Methods: Forty large ear rabbits were perfused with pure ethanol to make models of gastric mucosa damage. The influence of acupuncture on the function of the gastric movement before and after gastric mucosa damage was observed. Results: Before and after development of model of gastric mucosa damage, there was significant difference in amplitude index percentage of the gastric movement.Compared:with that before development of the model, the amplitude index after development of the model was lowered remarkably (P< 0.01). Acupuncture of Sibai (ST.2) and Zusanli (ST.36), could reinforce gastric movement. The amplitude index of gastric movement was remarkably increased after acupuncture as compared with that before acupuncture (P< 0.01). The effect of Sibai (ST.2) was most remarkable and after gastric mucosa damage acupuncture of Sibai (ST.2) could strengthen gastric movement. Conclusion: After gastric mucosa damage the amplitude index of gastric movement was remarkably lowered and acupuncture of Foot-Yangming meridian points could increase index of gastric movement, indicating that meridian of Foot-Yangming and stomach have a interrelationship.
