Abstract

To compare the effects of electroacupuncture (EA) of different acupoint groups on heart rate variability (HRV) and cerebral glutamate (Glu) and aspartic acid (Asp) contents in cerebrocardiac syndrome (CCS) rats. A total of 52 Wistar rats were randomized into normal (n = 8), sham-operation (sham, n = 8), model (n = 12), Shuigou-Fengfu (GV 26-GV 16, n = 12), and Neiguan-Xinshu (PC 6-BL 15, n = 12) groups. CCS model was established by intracerebral (Caudate nucleus) injection of clostridiopeptidase (1 U/microl) plus heparin (7 U/microl). EA (2 Hz/100 Hz, 1-3 mA) was applied to GV 26-GV 16 and PC 6-BL 15 for 20 min, once daily for 3 days. Cerebral Glu and Asp contents were detected by high performance liquid chromatography, and HRV was analyzed by SMUP Software. In comparison with normal and sham groups, the R-R interval (RRI) of electrocardiogram and total variability (TV) of HRV, cerebral Glu and Asp contents in model group increased significantly (P < 0.01, P < 0.05), and the ratio of low frequency/high frequency (LF/HF) decreased evidently (P < 0.01). Compared with model group, RRI and TV values, and cerebral Glu and Asp contents of EA of GV 26-GV 16 and PC 6-BL 15 groups reduced markedly (P < 0.01, P < 0.05), LF/HF of the late...Continue Reading
