Combined treatment ameliorates MPTP-induced dopaminergic neurodegeneration in the striatum. (a) Immunohistochemistry of TH-positive dopaminergic nerve fibers in the striatum (scale bar; 200 μm) and optical density of TH-positive dopaminergic nerve fibers in the striatum. (b) Expression of TH in the striatum by western blot and quantification of TH expression relative to β-actin for each group. ^∗∗p < 0.01 and ^∗∗∗p < 0.001 by one-way ANOVA followed by the Newman–Keuls post hoc test (n = 4 for each group).
