OBJECTIVE: To observe the effects of electroacupuncture (EA) of "Source-" + "Collateral-" acupoints ["Shenmen" ( @entity101 7) + "Zhizheng"(SI 7)] and single acupoints "Neiguan"(PC 6) and @entity101 7 on cardiac function and myocardial enzymes in @entity741 ( @entity741 ) @entity95 . METHODS: Sixty Chinchilla @entity95 were randomized into normal control, model, Shenmen ( @entity101 7), Neiguan (PC 6), @entity101 7 + SI 7 groups, with 8 @entity95 in each. @entity741 model was duplicated by occlusion of the anterior descending branch of left coronary artery under anesthesia. EA (2 Hz,1 mA) was applied to acupoints @entity101 7, PC 6,and @entity101 7 + SI 7 for 10 min. The maximum ascending rate (+ dp/dt max) and maximum descending rate (-dp/dt max) of the left ventricular pressure (LVP) were recorded by using PowerLab System. Serum @entity880 dehydrogenase (LDH) and @entity908 kinase MB (CK-MB) contents were detected with chromatometry. RESULTS: Serum LDH and OK-MB contents increased significantly in model group than in normal control group (P < 0.01). Compared with model group, serum LDH and CK-MB contents decreased remarkably in PC 6, @entity101 7 and @entity101 7 + SI 7 groups (P < 0.01, P < 0.05), and the effects of @entity101 7 + SI 7 group were significantly superior to those of PC 6 and @entity101 7 groups in lowering serum LDH and CK-MB levels (P < 0.01, P < 0.05). Compared with the normal control group, + dp/dt max lowered significantly and -dp/dt max increased markedly in the model group (P < 0.01), while compared with the model group, + dp/dt max increased obviously and -dp/dt max decreased significantly in the three EA groups (P < 0.01, P < 0.05). The effects of @entity101 7 + SI 7 group were markedly superior to those of @entity101 7 and PC 6 in raising + dp/dt max and lowering -dp/dt max (P < 0.05, P < 0.01), and those effects of PC 6 group were evidently better than those of @entity101 7 group (P < 0.05, P < 0.01). CONCLUSION: EA of "Source-" + "Collateral-" aoupoints ( @entity101 7 + SI 7), @entity101 7 and PC 6 has a positive effect in improving changes of cardiac function and in lowering serum LDH and CK-MB contents in @entity741 @entity95 , and the effect of EA of @entity101 7 + SI 7 is superior to that of EA of single acupoint.
