摘要
目的探讨阿魏酸钠(sodium ferulate,SF)对NO供体硝普钠(SNP)引起的大鼠海马神经元凋亡的影响。方法采用MTT比色分析测细胞存活率,Hoechst33258荧光染色及DNA琼脂糖凝胶电泳分析等方法检测凋亡。结果不同剂量SF(10～160μmol/mL)预处理海马神经元6h可剂量依赖地对抗SNP引起的神经元凋亡,提高神经元的存活率;减少SNP引起的核固缩、凝聚和碎裂现象;DNA凝胶电泳图谱未见典型的"梯子状"改变。结论SF对NO供体SNP诱导的海马神经元凋亡具有明显的保护作用。
[Objective] To study the effects of Sodium Ferulate （SF） on apoptosis of cultured hippocampal neurons induced by nitric oxide-donor, Sodium Nitroprusside （SNP）. [Methods] Neuronal viability and morphology were tested by MTT assay and light microscope. Huoreseent staining with Hoehest 33258 and agarose gel electrophoresis was used to analyze apoptosis. [Results] Pretreatment with different concentrations of SF （10-160 μmol/mL） for 6 h increased the survival rate of neurons in a concentration-dependent fashion. SF prevented the neuronal nuclei from shrinkage, condensation and cleavage induced by SNP. It also blocked neuronal nuclear DNA fragmentation induced by SNP. [ Conclusion] These results indicated that SF can protect neurons from apoptosis induced by NO.
