摘要

目的：评价阿霉素和ｒＨｕＴＮＦ抗人结肠癌细胞株的序贯作用。方法：采用克隆生成试验（Ｈａｍｂｕｒｇｅｒ－Ｓａｌｍｏｎ法），研究ＤＯＸ和ｒＨｕＴＮＦ序贯作用于ＣＯＬＯ２０５细胞株后的抗增殖效果。结果：对结肠癌细胞系ＣＯＬＯ２０５，存在ＤＯＸ－ｒＨｕＴＮＦ序贯抗增殖作用；多数联合给药情况下出现相加／协同作用。结论：ＤＯＸ存在时，ＴＮＦ的抗瘤作用增强，从而支持ＤＯＸ可干扰细胞保护机制以使瘤细胞对ＴＮＦ细胞毒作用更为敏感的理论。

Abstract

Objective: To evaluate the sequential action of rHuTNF and doxorubicin (DOX) against hurnan colon cancer cell line (COLO205 ). Method: With clonogenic aSSa(Hamburger -- Salmon methed)

the sequen- tial roles of rHuTNF and DOX on COLO205 were investigated. The dose -- effect relationships of each drug alone and in combination were analyzed by examining the survival fraction of the drug combination. Results: The ac- tion of DOX and rHuTNF against proliferation was found to be schedule -- dependent in colon cancer line CO- LO205;marked synergistic effects were observed in most instances of trearment

when DOX was administered prior to and not following rHuTNF. Chnclusion: The anti -- tumor effect of TNF can be enhanced in the presece of DOX

suggestion that the addition of DOX may interfere with the cellular protective mechanism

causing the tumor cells to become rae susceptible to the cytotoxic action of TNF.
