采用MTT细胞毒实验分别测定不同浓度的国产蜂胶对体外培养人肝癌细胞株细胞的杀伤率 ,并与商业化标准蜂胶 (Sigma #P_1010)比较。结果示国产蜂胶和标准蜂胶对肝癌细胞均有杀伤作用 ,且呈浓度 -抑制率相关关系 ,而对正常细胞的影响较小。
MTT cytotoxicity assay was used to determine the killing rate of domestic propolis with different concentrations on human hepatocellular carcinoma cell lines in vitro and compared with commercial standard propolis (Sigma # P_1010). The results showed that domestic propolis and standard propolis on the liver cancer cells have killing effect, and the concentration - inhibition rate, while the impact on normal cells smaller.
