The untreated 6-OHDA group shows almost no TH immunopositive cells, as related to the 6-OHDA group after SEMU treatment, at the dose of 40 mg/kg, p.o. (magnification: 400x). Arrows indicate TH immunopositive cells. (b) shows the means ± SEM of the number of TH immunopositive cells (three different fields) in each group. versus the untreated 6-OHDA group (, df = 7.0, ).
