摘 要: 采用台盼蓝计数、流式细胞仪分析等方法,离体研究玉米赤霉烯酮对小鼠胸腺上皮细胞增殖与细胞周期的影响,结果发现:不同质量浓度(1~25mg/L)玉米赤霉烯酮对小鼠胸腺上皮细胞的增殖均具有显著抑制作用(P〈0.05),并表现出与剂量和处理时间依赖性关系。高剂量(10~25mg/L)ZEA使小鼠胸腺上皮细胞细胞周期显著阻滞于G2/M期(P〈0.05),并存在剂量依赖性关系。这些结果表明,玉米赤霉烯酮对小鼠胸腺上皮细胞有直接毒害作用。 To elucidate the effects of Zearalenone(ZEA) on proliferation and cell cycle of cultured thymie epithelial cells in mice,trypan blue staining and flow cytometric analysis were performed. At the concentrations from 1 to 25 mg/L,ZEA displayed a significant inhibitory action to proliferation of thymic epithelial cells in its dose-and time- dependent manner. Higher doses(10-25 mg/L)ZEA could induce a profound increase in G2/M phase with arrest of thymic epithelial cells in the G2/M phase in a dose dependent manner. In conclusion, ZEA could be assumed that there were toxic effects on the thymic epithelial cells of mice in vitro.
