Abstract: BACKGROUND AND AIM: To investigate the synergistical suppressive effect of cadmium chloride and cisplation on the proliferation of human hepatoma cell line SMMC-7721. MATERIALS AND METHODS: Cytotoxicity of the drugs was measured by MTT assay. The coefficient of drug interaction(CDI) was used to analyze the synergistical suppressive effect of drug combination. RESULTS: 0.56、1.12、2.25 μg/ml cadmium chloride and 0.25、0.5、1.0 μg/ml cisplatins had inhibitory effects on the proliferation of SMMC-7721.The inhibition in cells treated with both agents was significant increased with treatment time. CONCLUSION: The combination of cadmium chloride and cisplatin could inhibit the proliferation of human hepatoma cell line SMMC-7721.

Key words: cadmium, cisplation(C-DDP), SMMC-7721, synergistical suppressive effect
