摘  要:
本文研究茶儿茶素诱导白血病癌细胞凋亡的作用及其机理。结果表明 ,茶儿茶素 (包括EGCG ,ECG和EGC)在浓度超过 5 0 μg ml时促进白血病癌细胞的凋亡 ,并在 5 0~ 30 0 μg ml浓度范围内存在正的量 -效关系。茶儿茶素诱导癌细胞凋亡的可能机理之一是促进自由基的产生 ,并抑制癌细胞的抗氧化酶

摘  要:
The effect on the apotosis of K562 leukemia cell and the possible mechanisms of catechins on the anti carcinogenetic activity were investigated Results showed that the catechins (including EGCG,ECG and EGC)induced the apotosis of K562 leukemia cell and showed effect-dose relationship within 50~300 μg/ml The possible mechanisms are that catechins caused the production of free radicals and inhibited the activities of anti oxidase such as superoxide dismutase and catalase
