By determination of ROS and apoptosis of Hela cells in mice at different hours after treatment with DDP, ADM or VP-16, the relations between apoptosis of Hela cell induced by chemotherapic Drug and concentration of ROS has been investigated. It has been found that there is no effect on apoptosis, and the P53 and c-fos expressions, of the Hela cells when SOD was applied 24 hours after the chemotherapy, whereas apoptosis of the Hela cells reduced when SOD was applied beforethe chemotherapy. Comparing with the control group, to which just ADM and DDP were given, ROS levels reduced markedly in bone marrow, liver and spleen of the tumor-bearing mice, which had been treated with SOD for five consecutive days 4 hours after the chemotherapy. It can be inferred that the oxidation damage of normal tissue can be avoided with scavenge of excessive ROS and increase of anti-oxidative enzymes by SOD in the chemotherapy. The results suggest that injecting SOD at suitable time in clinic chemotherapy may be useful for reducing the side effects.
