Figure 3: Immunohistochemical microphotographs of iNOS- immunoreactivity in the cerebral cortex of mice (iNOS immunostaining with hematoxylin counterstain, × 400). (A) Vehicle: no iNOS immunopositive reaction. (B) Rotenone: strong iNOS immunoreactivity. (C-E) Rotenone + misoprostol 10, 100 or 1 000 μ g/kg: decreased iNOS immunoreactivity in a dose-dependent manner. |
