摘要: 应用MTT比色法研究了重组人肿瘤坏死因子(rhTNFα)对白血病细胞株HL60和K562生长的抑制作用。实验结果表明,rhTNFα对白血病细胞生长的抑制作用有时相和剂量依赖关系。rhTNFα与HL60和K562细胞分别培养12h,抑制率仅有6.2%和4.3%.当作用时间延长到24h时,抑制度分别达到55.4%和47.1%.rhTNFα的用量由0.04μg/2×105细胞增加到5μg/2×105细胞时,对HL60和K562细胞的生长抑制率也分别由16.8%和6.4%增长到77.1%和59.3%.上述两种依赖关系的实验数据经单因素方差处理,有显着性差异。rhTNPα同抗肿瘤药Vp16合用对白血病细胞生长的抑制有叠加作用。rhTNFα加入急性粒细胞白血病患者骨髓细胞培养体系后,对白血病细胞集落形成单位(CFU-L)的生长有一定抑制作用。当rhTNFα为1μg/5×105白血病细胞时,对CFU-L的抑制率可达43.4%.

Abstract: The effect of recombinant human tumor necrosis factor-a(rhTNFα)on leukemic cells was investigeted.The suppressive effect of rhTNFon HL60 and K562 leukemic cells was time and dose dependent.After incubation for 24 hours,the suppressive effect of rhTNFαon HL60 and K562 cells should be above 1μg at 2×105 leukemic cells.Our work indicated that rhTNFαwhen used conjointly with Vp16 exerted a synergetic action on inhibiting the growthof leukemic cells and that these results of two methods were generally the same. The suppressive effect of rhTNFαon colony forming unit-leukemia(CFU-L)in two patiensts with acute myelogenous leukemia was shown.These observations suggested that the rhTNFαcould be used to treat the patient with acute myelogenous leukemia.

Key words: rhTNFα(recobinant human tumor necrosisfactor-a), leukemia, MTT(tetrazolium-based semiautomated colorimtric assay)
