心经经脉与相应脏腑相关的研究——电针心经对家兔心功能、小肠及脑电活动的影响

目的 :了解分别电针心经、肺经循行路线上的 3个测试点以及不电针的对照组对心功能、小肠及脑电活动的影响。方法 :以左心室内压峰值 (LVP)、左心室内压变化上升最大速率(LVPdp/dtmax)、心力环面积 (ACFL)、心肌收缩成分最大缩短速度 (Vmax)、小肠电图及脑电图为指标 ,静脉滴注垂体后叶素造成心肌缺血动物模型进行观察。结果 :电针心经对心功能、小肠及脑电活动的调节作用比电针肺经显著 ,有相对特异性。结论 :心经作为一条经脉 ,与心功能、小肠及脑电活动有密切关系

Study on the Interrelation between the Heart Meridian and the Related Internal Organs in the Myocardial Ischemia Rabbit

Objective:To probe into the effect of electroacupuncture (EA) of 3 points of the Heart Meridian and 3 points of the Lung Meridian on the cardiac function, small intestinal electrogram (SIEG) and electroencephologram (EEG) in acute myocardial ischemia (AMI) rabbits. Methods: A total of 30 rabbits anesthetized with urethane (1 g/kg) were randomized into control group, Lung Meridian group and Heart Meridian group with 10 cases in each group. AMI was induced by intravenous drip of posterior pituitary hormone. "Shenmen"(HT 7), "Lingdao"(HT 4) and the midpoint between them of the Heart Meridian, "Taiyuan"(LU 9), "Lieque"(LU 7) and the midpoint between these two acupoints of the Lung Meridian were punctured and stimulated electrically with ZYZ 1 EA Therapeutic Apparatus.Left ventricular pressure (LVP),dp/dtmax,the area of myocardial force loop (ACFL) and the maximal shortening velocity of the myocardium( Vmax ), SIEG and EEG were used as the indexes. Results: After AMI, LVP,dp/dtmax, ACFL,Vmax,the amplitudes of SIEG and EEG decreased significantly in comparison with their basic values ( P <0.05～0.001), and then recovered gradually 10～30 min later. No significant differences were found between Lung Meridian group and control group in the above mentioned indexes, but there were significant differences between Heart Meridian group and control group, and between Heart Meridian group and Lung Meridian group in all the indexes ( P <0.05～0.01).Conclusion: Results indicate that the regulative effects of EA of acupoints of the Heart Meridian are better than those of EA of acupoints of the Lung Meridian in improving AMI induced changes of the cardiac activity,SIEG and EEG. The whole Heart Meridian has a close relationship with the heart,the small intestine and the cerebral cortex.
