BCG对体外培养人癌细胞直接作用的扫描电镜观察

SCANNINGECTROMICRO5COPIC OBSERVATION OF DIRECT ACTION OF BCGON HUMAN HELA CELLS CULTURED IN VITRO

用不同浓度卡介苗（ＢＣＧ）与人宫颈癌Ｈｅｌａ细胞作用不同时间，用扫描电镜进行细胞表面超微结构的观察。结果发现ＢＣＧ对靶细胞有直接损伤的作用。

Effect of BCG in different concentration and with varied duration of it 's application upon human Hels cells was studied in vitro by tissue culture, at the same time the ultrastructural changes were observed notably in the Hela cells by Scanning Electron Microscopy.The results showed that BCG had a immediate damage effect on target cells which documented by the surface morphological changes.
