Each value is a mean of 4 rats ± SD; a, b, c, d values are not sharing superscripts letters (a, b, c, d) differ significantly at p<0.05; Damage index (DI) = cells number of each class × number of classes (O-4), maximum value=400 arbitrary unit); Damage frequency %(DF) = (number of cells with tail/ number of cells without tail) ×100; DM: Dimethoate; VC: vitamin C; SAC: Synthetic antioxidant compound
