Data are mean ± standard error of the mean S.E.M. values. * Values significantly different from the control group; # Values significantly different from PTZ group. ANOVA and Tukey’s post-hoc test (p ≤ 0.05) were used. DNPH: Dinitrophenylhydrazine; SOD: Superoxide dismutase; DTNB: 5,5′-dithiobis(2-nitrobenzoic acid).
