摘要: 活性氧如H2O2、O2以及OH·造成的生物分子及细胞损伤与许多神经退行性疾病如阿尔茨海默病、癫痫和帕金森氏病等有关。本实验对Wistar大鼠脑星形神经胶质细胞进行了分离和原代培养,以此为材料检测了大麦提取物对由H2O2处理引起的细胞生长抑制的保护作用。通过细胞形态学观察和SRB法测定细胞生长率,实验结果表明大麦提取物对H2O2诱导下星形胶质细胞生长率降低具有一定的保护作用,且呈浓度依赖性,当大麦提取物浓度增加到1600 μg/mL时,细胞生长率达到100%。

Abstract: Reactive oxygen species(ROS)such as H2O2, O2 and OH· are related to neurodegenerative diseases,including Alzheimer’s disease,Epilepsy,Parkinson’s disease, etc. In this study,the astrocytes of Wistar rat were separated and cultured.It was used as the raw material for detecting the protective effect of barley extracts on the cell growth inhibition induced by H2O2.The cell morphology was then observed and the cell growth rate was determined by SRB method.The experimental results indicated that barley extracts had the protective effect on the decrease of the growth rate of astrocytes under the induction of H2O2, in which there was a trait of concentration dependence,namely when concentration of barley extracts increased to 1600 μg/mL,the growth rate of cells was 100%.

Key words: reactive oxygen species, barley extracts, astrocyte, the growth rate of cells
