NDI1 can restore TH content (indicating dopamine content) in striatum of MPTP-induced PD mouse model. A: Tyrosine hydroxylase (TH) content in striatum examined by immunohistochemical staining with TH antibody (brown) (scale bar: 500 μm). B: Statistical histogram from A displaying TH-positive optical density value in striatum. ns: no significant difference, **: P < 0.01, ***: P < 0.001
