目的 探讨10 3 Pd粒子对人肝癌细胞 - 74 0 2的细胞毒作用 .方法 以体外培养的人肝癌细胞 - 74 0 2为研究对象 ,采用对照分组、体外细胞毒试验 (MTT)、方差分析 ,观察10 3 Pd粒子放疗对肝癌细胞 - 74 0 2的生长抑制作用 .结果 10 3 Pd粒子对肝癌细胞 - 74 0 2的细胞毒作用与照射时间、照射剂量有关 ,照射时间越长、照射剂量越大 ,细胞毒作用越强 .结论 人肝癌细胞 - 74 0 2对10 3 Pd粒子放疗敏感 .
Objective To investigate the cytotoxic effect of 10 3 Pd particles on human hepatocellular carcinoma cells-74 0 2 .Methods Human hepatocellular carcinoma cells-74 0 2 cultured in vitro were used as control subjects, and were divided into control group, in vitro cytotoxicity test (MTT) and analysis of variance. Observed the inhibitory effect of 10 3 Pd particle radiotherapy on the growth of hepatocellular carcinoma cells - 74 0 2 . Results The cytotoxic effect of 10 3 Pd particles on hepatocellular carcinoma cells - 74 0 2 was related to the irradiation time and irradiation dose. The longer the irradiation time, the greater the irradiation dose. Larger, the stronger the cytotoxicity. Conclusion Human liver cancer cells - 74 0 2 sensitive to 10 3 Pd particles radiation therapy.
