电针“神门”、“太溪”穴对急性心肌缺血家兔的效应比较

Comparison on the Effects on Acute myocardial is chemia Rabbits with Electro - acupuncture “Shenmen”or “Taixig”

目的:探讨电针"神门"、"太溪"穴对急性心肌缺血家兔心功能的影响,比较同名经原穴间的效应差异。方法:健康青紫蓝家兔40只,随机选择8只健康家兔作为正常对照组,余家兔经股静脉一次性注射垂体后叶素3U/kg进行模型复制。将模型复制成功的家兔随机分为模型对照组、电针"神门"组、电针"太溪"组和电针非经穴组,每组8只。观察电针前后各组家兔心功能变化情况。结果:电针"神门"组家兔的+dp/dt max、-dp/dt max、LVSP与模型组、电针非经穴组及电针"太溪"组比较差异有统计学意义(P<0.05)。电针"太溪"穴及电针非经穴组的+dp/dt max、-dp/dt max及LVSP与正常组比较差异有显著性意义(P<0.05),与模型比较差异无统计学意义(P>0.05)。结论:手少阴心经的原穴"神门"对心脏功能的调节作用优于其同名经的原穴"太溪"。

Objective ： To observe the treatment effects of electro - acupuncture at ＂Shenmen＂ （ HT7 ）, ＂Taiyuan＂ （ KI3 ） on the acute myocardial ischemia （AMI） rabbits. To investigate the specificity effects of adjus ting cardiac function after electro - acupuncturing （EA） on different primary acupoints. Methods ： 50 healthy rab bits are selected, 8 are chosen randomly as normal group. The odd rabbits were developed acute myocardial ische mia models by intravenous administration posterior pituitrin into femoral vein, and AMI model rabbits were random ly divided into model group, EA on HT7 group, EA on KI3 group, and EA on nonpoint group, 8 in per group. To treat AMI rabbits by EA for 10rain, and to record cardiac function. Results ： The ＋ dp/dt max and LVSP of EA on HT7 group are higher obviously than model group, EA on KI3 group and EA on nonpoint group after EA. Con- clusions： There is specificity in the effects of EA on different Primary acupoints with the best effect on Shenmen （HT 7 ） , and no effect on Taixi （KI 3） .
