电针手三阴经原穴对急性心肌缺血家兔心功能的影响

目的 比较电针“大陵”、“神门”和“太渊”对急性心肌缺血家兔心功能的影响，探讨手三阴经原穴间的相对特异性作用。方法 50只家兔分为正常对照组、模型对照组、电针大陵组、电针太渊组和电针神门组，采用静脉注射脑垂体后叶素复制急性心肌缺血模型，用Biopac生物信号采集系统记录电生理信号，同时接入SKY—A8生物信号处理系统进行统计分析，记录电针不同经穴对急性心肌缺血家兔心功能的影响。结果 电针大陵组、电针神门组对心率、室内压上升段最大变化率和左心室收缩压力峰值的改善明显优于电针太渊组（P〈0．01），且与模型组比较有统计学意义（P〈0．05）。结论 电针“大陵”、“神门”可显著改善急性心肌缺血家兔的心功能，而电针“太渊”穴未见明显作用。

Effects of Electroacupuncture of Primary Acupoints of Yin Meridian of Hand on the Cardiac Function in Acute Myocardial Ischemia Rabbits

Objective： To observe the effects of electrocacupuncture （EA） of Daling（PCS）, Shenmen（HTT）, Taiyuan（LU9） poitnts on acute myocardial ischemia rabbits, and compare their cardiac function with control groups. Methods： 50 rabbits were randomly divided into normal control group, model control group, group of EA on PC5, group of EA on HTT, group of EA on LU9. To develop acute myocardial ischemia models with intravenous adminstration of pituitrin. To record the changes of cardiac function after EA on different acupoints. Results： The heart rate, left ventricular systolic pressure （LVSP）, rate of rise of left ventricular pressure（ ＋ dp/dt max） after EA on PC5 and HT7 had statistical significance comparing with EA on LU9 and model control group. Conclusion： The cardiac function of acute myocardial ischemia rabbits can be improved after EA on PC5 point or HT7 point. EA on LU9 has not the similar effects.
