(a) Immuno-histochemical staining of MUC 2 in colonic sections of rats treated with cadmium and Nigella sativa oil X400; MUC 2 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 MUC 2 expression in the different groups. *indicates significant difference (p=0.003) compared to the control group; ^#indicates significant differences (p=0.010 for Cd+NSO group and 0.008 for NSO group) compared to the Cd only group
