Photomicrographs of cresyl violet staining of the striatal tissue (lesioned right side) from untreated 6-OHDA and SEMU (20 and 40 mg/kg, p.o.) treated groups. The Sham-operated (SO) rats are the control group (a). A lower number of stained cells (indicating neuronal damage and nonviable neurons) are observed in the untreated 6-OHDA group, as related to the 6-OHDA groups treated with SEMU and mainly to the SO group (magnification: 400x). (b) shows the means ± SEM of the number of cells (three different fields), in each group. versus untreated 6-OHDA group (, ).
