Cicadidae Periostracum, the Cast-Off Skin of Cicada, Protects Dopaminergic Neurons in a Model of Parkinson’s Disease

Figure 3

Effects of CP on MPTP-induced dopaminergic neuronal death. Dopaminergic neurons were visualized by TH-specific immunostaining. The number of TH-immunopositive neurons in the SNPC (a) was counted, and the optical density in the ST (b) was measured. Dopamine levels in the ST were measured using ELISA (c). MAO-B inhibition rate in a cell-free system was measured using ELISA (d). Representative photomicrographs of the SNPC and ST were taken (e). Values are presented as . , , and compared with the control group and , , and compared with the MPTP-treated group (a, b, or c) or control group (c in the cell-free system).
