Abstract:
This study was aimed to explore the mechanism of electroacupuncture (EA) on improvement of Parkinson’s disease (PD). A total of 40 SD male rats were randomly divided into 4 groups, which were the normal group, sham-operation group, model group, and EA group (n=10). The 6-hydroxydopamine (6-OHDA) was used to prepare PD rat rotational model. The 0.2% Vitamin C of physiological saline was injected in the sham-operation group. EA on GV16-Fengfuand LR3-Taichongwas given for 30 min in the EA group after the model was successfully established, once a day, 7 days a treatment course. The treatment was given for 2 courses. Behavioral test was used to detect PD rat rotational behavior changes. Glu concentration in the striatum was detected by HPLC assay. The expression levels of GS and PAG were detected with western blot. The results showed that there were significant differences in the rotational behavior before and after treatment in the EA group (P < 0.01). Compared with the normal group and sham-operation group, Glu concentration significantly increased, GS expression obviously decreased, and PAG expression significantly increased in the model group (P < 0.01). Compared with the model group, Glu concentration obviously decreased (P < 0.05), GS expression significantly increased, and PAG significantly decreased in the EA group (P < 0.01). It was concluded that the protective effect of EA in PD may be associated with EA improving the expression of GS, reducing the expression of PAG, and relieving the cytotoxicity induced by Glu in the brain.
