21625423 The antioxidative effect of electro-acupuncture in a mouse model of Parkinson's disease. PLoS One. 2011;6(5):e19790. doi: 10.1371/journal.pone.0019790. Epub 2011 May 23. 2011 Accumulating evidence indicates that oxidative stress plays a critical role in Parkinson's disease (PD). Our previous work has shown that 100 Hz electro-acupuncture (EA) stimulation at ZUSANLI (ST36) and SANYINJIAO (SP6) protects neurons in the substantia nigra pars compacta from 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) toxicity in male C57BL/6 mice, a model of PD. In the present study we administered 100 Hz EA stimulation at the two acupoints to MPTP-lesioned mice for 12 sessions starting from the day prior to the first MPTP injection. We found that in the striatum of MPTP treated mice 100 Hz EA stimulation effectively inhibited the production of hydrogen peroxide and malonaldehyde, and increased glutathione concentration and total superoxide dismutase activity through biochemical methods. However, it decreased glutathione peroxidase activity via biochemical analysis and did not affect the level of 1-methyl-4-phenylpyridinium in the striatum revealed by high performance liquid chromatography with ultraviolet detection. These data suggest that 100 Hz EA stimulation at ST36 and SP6 has antioxidative effects in the MPTP model of PD. This data, along with our previous work, indicates that 100 Hz EA stimulation at ST36 and SP6 protects the nigrostriatal system by multiple mechanisms including antioxidation and antiapoptosis, and suggests that EA stimulation is a promising therapy for treating PD."

Evidence Sentence: Here we assessed whether EA stimulation could rescue DA neurons in the SNpc from MPTP toxicity by TH immunohistochemistry.
Evidence Sentence: We found that on day 14, TH positive neurons in MPTP treated mice dramatically decreased (p<0.05 vs.
Evidence Sentence: However, TH immunoreactivity could be rescued by 100 Hz EA stimulation (p<0.05 vs.
Evidence Sentence: Consistent with the TH immunohistochemistry results, 0 Hz EA stimulation did not affect the concentrations of DA, DOPAC and HVA in the striatum of the MPTP treated mice.
