In order to investigate protection effects of SOD on the oxidized damage of normal tissues induced in chemotherapeutic drug and irradiated tumor−bearing mice, the contents of ROS and MDA, the activation of GSH−Px and CAT in liver, kidney, spleen and bone marrow have been determined. The effect of SOD on the ultra−structure of liver cell has been evaluated. It has been found that chemotherapeutic drug and irradiation can increase the contents of ROS and MDA and decrease activation of GSH−Px and CAT. And SOD can decrease contents of ROS and MDA and increase the activation of GSH−Px and CAT slightly for liver, spleen, marrow, but for kidney there is no significant change while SOD can reduce the damage of ultra−structure of liver. It can be inferred that SOD have some protection effects on the normal tissue of tumor−bearing mice via scavenging free radicals and activate anti−oxidative enzymes after TBI and drugs injection.
