摘要: 目的:研究神经生长因子( Nerve Growth Fac- tor,NGF) 和神经节苷脂GM1 (Ganglioside GM1 ) 对 2, 5- 己二酮( 2, 5-HD) 中毒的保护作用。方法:将细胞随 机分为对照组和实验组, 对照组于正常培养基生长, 实验组以 2, 5-HD 、NGF 和 GM1 处理。采用 Giemsa 染色法在倒置显微镜下观察细胞形态,MTT 法检测 细胞存活率, 流式细胞计数法检测细胞凋亡率 。结 果:2, 5-HD 处理后, 细胞损伤存活率降低( P < 0 .01) , 凋亡率上升( P <0 .01) ;以 NGF 和 GM1 预处 理的细胞显示出明显的抗损伤性, 细胞存活率提高 ( P <0 .05) , 凋亡率下降( P <0 .05) , 且在联合时较 单独应用效果更显著( P <0 .01) 。结论:2, 5-HD 抑 制PC12 细胞存活和增殖, 诱导细损伤和凋亡。NGF 和GM1 对 2, 5-HD 中毒性 PC12 细胞显示出协同保 护作用。

Abstract: AIM:To investigate whether NGF and GM1 have synergistic protective effect on 2, 5-HD intoxi- cation in PC12 cells .METHODS :Cells were divided into control group and treated groups at random .Control group was maintained in normal medium ;treated groups were exposed to 2, 5-HD with or without NGF, GM1 .The cells' morphological changes were observed by inverted microscope after being dyed with Giemsa .The cell via- bility was determined by MTT assay .The apoptotic ratio was determined by flow cytometry ( FCM) .RESULTS: PC12 cells which was treated by 2, 5-HD injury aggravat- ed, the cell viability decreased ( P <0 .01) , and the ap- optotic ratio increased ( P <0 .01) .PC12 cells pretreated with NGF and GM1 obviously resisted injury, the cell via- bility increased ( P <0 .05) , apoptotic ratio decreased ( P <0 .05) .Combination of NGF and GM1 afforded addit- ional protection that was greater than that of either agent individually ( P <0 .01) .CONCLUSION:2, 5-HD in- hibited the survival, induced apoptosis and injury of PC12 cells.NGF and GM1 showed synergistic protective effect on 2, 5-HD intoxication in PC12 cells .

Key words: NGF , ganglioside GM1 , 2, 5-hexanedi- one, synergistic protective effect
