Results of the MTT assay showed that GBS exhibits a significant cytotoxic effect in HL-60 cells, and we found that the cytotoxic effect is a result of apoptosis as evidenced by morphological change, DNA fragmentation, and flow cytometry.

• MTT还原测定(单核细胞直接细胞毒性测定)结果显示GBS对HL-60细胞有明显的细胞毒作用,通过形态学改变、DNA断裂及流式细胞计量术,我们发现其细胞毒作用是凋亡的结果。
