摘要: 采用不同浓度H2O2处理H9c2心肌细胞,MTT法检测复方龙脉宁(Compound Longmaining,CLMN)水提液和醇提液含药血清(5%、10%、20%组)对氧化损伤的H9c2心肌细胞活性的影响,研究CLMN提取液对H2O2导致H9c2心肌细胞氧化损伤的修复作用。结果显示,当H2O2浓度为100μM,作用时间24 h,可建立稳定的H9c2心肌细胞氧化损伤模型;与对照组相比,经H2O2处理后的细胞活性明显下降,SOD活性显著降低,而LDH活性、MDA含量则显著增加,而用CLMN水提液和醇提液含药血清(10%、20%组)处理氧化损伤的H9c2心肌细胞,可显著提高细胞存活率及 SOD活性,降低LDH活性和MDA含量。说明CLMN水提液和醇提液均对H2O2诱导H9c2心肌细胞氧化损伤具有很好的保护作用。

Abstract: H9c2 cardiomyocytes were treated with different concentrations of H2O2.The effect of Compound Longmaining (CLMN) water extract and alcohol extract (5%,10%,20% group) on H9c2 cardiomyocytes injured by H2O2 was detected by MTT assay.The results showed that a stable H9c2 cardiomyocytes injury model can be established when the concentration of H2O2 was 100 μM and the action time was 24 h.Compared with the control group,the activity of the cells decreased obviously after treatment with H2O2,and the activity of SOD decreased significantly,but the activity of LDH and the content of MDA increased significantly.While CLMN water extract and ethanol extract serum containing drugs (10%,20% groups) can significantly improve cell viability and SOD activity,as well as reduce LDH activity and MDA content.The results indicated that CLMN water extract and ethanol extract can protect H9c2 cells from oxidative injury induced by H2O2.

Key words: CLMN extract, H9c2 cardiomyocytes, MTT method, myocardial oxidative injury
