Fig. 1. (A) Effect of SFN and Ar on the activities of ALAD in blood and liver of control and experimental rats. (B) Effect of SFN on the accumulation of As in liver tissue 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).
