Fig. 6. Effect of SFN on the impact of As induced RT-PCR changes in SOD1 (A) and CAT (B) of control and experimental rats. Values are expressed as mean ± SD for groups of eight rats in each. Statistical significance was determined by one way ANOVA (Duncan's Multiple Range Test). Values not sharing a common or same alphabet letter (^a-f) and they differ significantly at P<0.05 (Duncan's multiple range test).
