摘要: 背景与目的: 研究氯化镉和顺铂联合对人肝癌细胞SMMC-7721增殖的抑制作用。 材料与方法: 采用MTT法测定不同浓度氯化镉和顺铂对人肝癌细胞SMMC-7721增殖的抑制作用;应用两药相互作用指数进行联合作用分析。 结果: 0.56、1.12、2.25 μg/ml的氯化镉联合0.25、0.5、1.0 μg/ml的顺铂可协同抑制SMMC-7721增殖,且随着作用时间延长,协同抑制作用增强(P<0.05或 P<0.01)。 结论: 氯化镉与顺铂联合应用可以协同抑制人肝癌细胞SMMC-7721的增殖。

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
