Substantia nigra tyrosine hydroxylase (TH) expression in rats (immunofluorescent staining, × 200).
TH-positive reaction was represented by red fluorescence. A large number of TH-positive cells were observed in the control group (A). Compared with the control group, the number of TH-positive cells was significantly decreased in the vehicle-treated (model) group (B). Anchanling (C) increased TH-positive cells in rats compared with the vehicle-treated group.
