EFFECT OF ACUPUNCTURE AT NEIGUAN POINT ON TRANSMEMBRANE POTENTIAL AND cAMP AND cGMP OF MYOCARDIAL CELL OF RABBITS WITH ACUTE MYOCARDIAL ISCHEMIA

28 health rabbits were divided into electroacupuncture group, and non-elec- troacupuncture. Effect of electrical needling "Neiguan" point on the action potintial and cAMP and cGMP of the ventricular cells of acute myocardial ischemia were observed.The main results are as follows: The RP, APA and maximun velecity of depolarization(Vmax) decrease, the APD prolongs in the electroacupuncture and non-electroacupuncture group, but the changes of non-electroacupuncture group are more evident than the electroacupuncture group.The attack rates of EAD and DAD in the nonelectroacupuncture group are higher than in elec troacupuncture group. cAMP in the acute myocardial ischemia cells increases, but the changes of which in nonelectroacupuncture group are more marked than the electroacupunct u re.The above mentioned results show that there is a protection effect of electrical needling "Neiguan"point on the action potential of the ventricular cell of acute myocardial ischemia rabbits. The effect might result from decreasing cAMP in the ischemia cells by electrical needling "Neiguan" point.
