摘要 目的 研究F - 2毒素引起体外培养细胞 (HELA细胞 )的DNA损伤。方法 应用单细胞凝胶电泳技术 (SCGE) ,测定玉米赤霉烯酮 ,即F - 2毒素。结果 F - 2毒素在 1~ 1 5 μg/mL细胞悬液浓度范围内能够引起细胞DNA损伤并存在明显的剂量反应关系。结论 不同剂量的F - 2毒素可引起体外培养细胞拖尾 ,说明F - 2可致DNA损伤 ,但其修复机制还存在。 DNA damage of HELA cells by F-2 toxin was determined by single-cell gel electrophoresis (SCGE). Results showed that F-2 toxin at the level of 1 to 15 μg/mL caused DNA damage in a dose-dependent pattern. The results were discussed briefly in this paper.
