A. PAGE profile of SOD isoenzymes (Mn-SOD, Cu/Zn-SOD) in the kidneys. Control, Cd-exposed, Cd + Ca + Zn supplementation, and Cd + Vit-E supplementation conditions are indicated as control, Cd, Cd + Ca + Zn and Cd + Vit-E, respectively. B. PAGE profile and densitometry graph of the Mn-SOD isoenzyme in the kidneys of all experimental groups. C. PAGE profile and densitometry graph of the Cu/Zn-SOD isoenzyme in the kidneys of all experimental groups.
