Fig. 3. Rg1 ameliorated striatal neuronal loss induced by 3-NP.

a–g, a’-g’ Nissl staining of striatal neurons across groups. h The counting results of Nissl staining-positive cells in the striatum. i, j The representative blots and densitometry data for DARPP-32 in the striatum across groups. Data are expressed as the mean ± SEM, n = 3. ^###P < 0.001 vs control group; ^*P < 0.05, ^**P < 0.01 vs model group. Scale bars, (a–g) 500 μm; (a’-g’) 50 μm.
