In order to analyze the change of micronucleus in the p53 mutant human breast cancer cells MDA-MB-435 caused by artemisinin additive, MTT method was used to check the effect of different concentration and treatment time of artemisinin to cytotoxicity. Cytokinesis block micronucleus method (CB method) was used to determine the micronucleus frequency (MNF) and the micronucleus cell frequency (MNCF) of cells treated by artemisinin additive and with different doses of ,60,Co γ-rays. The experiment results show that artemisinin is of little toxicity to MDA-MB-435. When drug concentration is 200μmol/L and treatment time is 24 h, the dose-response curves of MNF and MNCF of irradiated cells combined with treatment of or not artemisinin additive confirm that MNF and MNCF of cells treated by artemisinin are both significantly higher than that treated by radiation alone. It can be deduced that artemisinin may have some sensitive action on radiation therapy.
