(a) Immuno-histochemical staining of Tumor Necrosis Factor (TNFα) in colonic sections of rats treated with cadmium and Nigella sativa oil X400; TNFα expression is indicated as golden brown coloration (black arrows) on tissue structures. A, control; B, Cd only; C, Cd+NSO; D, NSO only. (b) The mean area% of TNFα expression in the different groups. *indicates significant difference (p=0.029) compared to the control group; #indicates significant differences (p=0.035 for Cd+NSO group and 0.017 for the NSO group), compared to the Cd only group; @indicates significant difference (p=0.023) compared to the Cd+NSO group
