Objective To observe the synergetic protective effect of electro-acupuncturing(EA) at PC6 and BL15 against acute myocardial ischemia in rats.Methods 40 rats were randomly divided into 5 groups,namely control group,model group,PC6 group(treated with EA at PC6 acupoint),BL15 group(treated with EA at BL15 acupoint),Guanshu group(treated with EA at both PC6 and BL15 acupoint).Injecting pituitrin into sublingual vein simulated the acute ischemic rats models.The changes of blood viscosity and blood rheology were ...
