摘要
采用体外造血细胞培养技术,应用高温、利多卡因、足叶乙苷(足叶乙甙,VP-16)联合法,研究其在体外对白血病细胞的杀伤作用。结果表明:高温、利多卡因、VP-16三者联用比高温+利多卡因、高温+VP-16,能更有效地杀伤白血病细胞,而正常粒单系克隆形成单位(GM-CFU)仍约有50%存活。41℃60min+0.75mmol/L利多卡因+8.5μmol/LVP-16联合处理后,HL-60、U937、K562细胞分别只存活0.01%、9.40%、33.66%。另外,从这个联合方案说明对于不同类型的白血病效果不一,在其自身骨髓移植(ABMT)时,体外净化骨髓要采用不同的净化方案。
sing the semi- solid t-CFU and GM-CFU culture method ,we investigated the effect of hyperthermia , lidocaine , etoposide on leukemic cell lines. and normal human bone marrow GM-CFU colony growth in vitro. The results showed that the combination of hyperthermia , lidocaine and etoposide could produce more additive tumor cell killing than hyperthermia plus lidocaine or , hyperthermia plus etoposide, while , under the same experimental conditions , normal hematopoietic precursors were spared , following hyperthermia 41 ℃ for 60min plus 0. 75mmol/L lidocaine plus 8. 5umol/L etoposide treatment ,the survival rate was 0. 01% for HL-60,9.94% for U937, 33. 97% for K562. These results also showed that the treatment had various effect on the different kinds of leukemia , so the different purging treatment should be used in ABMT.
