摘要: 目的: 研究毫米波和ADM 分别单独应用以及联合应用对 K562细胞株培养体系中的氧化自由基及抗氧化酶系的调控和影响,来探讨毫米波及 ADM对白血病细胞的作用机制,为研究白血病细胞体外净化方法提供理论依据 。方法: 将毫米波和阿霉素分别单独以及联合作用于 K562细胞株,测定细胞培养体系中超氧化物歧化酶(SOD) 和谷胱甘肽过氧化物酶(GSH-Px) 的活性,测定脂质过氧化产物丙二醛(MDA) 的含量。结果: 单用 ADM 或毫米波辐射均对K562细胞内 MDA 的含量有显著的增高(P<0.01);对K562 细胞内 SOD、GSH-Px 两种重要的抗氧化酶系的活性有显著的抑制作用(P<0.01) 。毫米波与ADM 联合应用能产生协同作用(P<0.01) 。结论: 毫米波和阿霉素联合作用于人白血病 K562 细胞能产生协同治疗效应,值得进一步研究。

Abstract: AIM: To study the effect of combination millimeterwave with adriamycin on regulating the antioxi-dase system andoxyradical in the cultured cell line system in vitro.METHODS: Leukemic cell line K562 was treated by millimeterwave alone and in combination with adriamycin.Then Intracellularmalondialdehyde(MDA)was analyzed with thiobarbituric acid method,superoxide dismutase (SOD) was analyzed with pyrogallic acid meth-od,and glutathione peroxidase (GSH-Px) was analyzed with improved Hafemanmethod.RESULTS: The combi-nation of millimeterwave and adriamycin had a synergistic effect on inhibiting superoxide dismutase and malondial-dehyde of leukemic cell line K562.The activity of SOD and GSH-Px was decreased and the content of MDA was improved by the combination.CONCLUSION: The combination of millimeterwave and adriamycin shows a synergistic effect on puring leukemic cells in vitro.
