Acupuncture ameliorates motor symptoms and delays onset of neuron damage in 6-OHDA lesioned rats. (A) Weight curve; sham n = 12/model n = 12/madopa n = 11/acupuncture n = 13. (B) Left: Rotation score. Rotation test was performed for each rat on day 15 and day 45. Right: Suspension score. Suspension test was performed for each rat on day 15 and day 45. Sham n = 5/model n = 5/madopa n = 11/acupuncture n = 13; SPSS13.0. One-way ANOVA analysis was used for multi-group comparison, and Dunnett and Bonferroni were used for post-test correction. *Compared with model on day 45 P < 0,05. (C) IHC: TH staining of the SN. Left: whole brain sections and representative images of the SN (40x magnification). Arrows indicate lesioned brain areas. Right: Quantification of TH + areas. 3 sections of 4 rats of each group were quantified and means ± SEM were calculated out of 12 sections in total for each group. One-way ANOVA analysis was used for multi-group comparison, and Dunnett and Bonferroni were used for post-test correction. **Compared with sham: P < 0,01; Δ compared with model: P < 0,05; ΔΔ compared with model: P < 0,01.
