五味子乙素对乳鼠缺氧／复氧损伤心肌细胞的保护作用及其机制
Protective effect of Schisandrin B on myocardial cells with hypoxia/reoxygenation-induced inj ury in neonatal rats and its mechanism
摘要
Abstract
Objective To investigate the influence of Schizandrain B(Sch B)preconditioning in myocardial cells of neonatal rats with hypoxia/reoxygenation (H/R)inj ury, and to explore its possible mechanism.Methods The cultured myocardial cells were divided into control group, model group and 10, 50, 250 mg · L-1 SchB preconditioning groups.All the cells in various groups except control group were cultured in 2 mmol·L-1 Na2 S2 O4 for 2 h,then cultured in normal medium for 18 h to induce myocardial H/R injury.The morphological changes of myocardial cells in various groups were observed under inverted microscope. The survival rates of the myocardial cells in each group were examined by MTT. The activities of lactic dehydrogenase (LDH ), creatine (CK ), superoxide ismutase(SOD),and the (MDA)levels in the cells in various groupswere examined by detection kits. Results Compared with control group,the cells in model group were retracted,arrest or float,the survival rate was decreased significantly (P<0.01),the activities of LDH,CK and MDA level were increased (P<0.01),and the SOD activity was decreased (P<0.01);compared with model group,the cells in Sch B preconditioning groups remained beating,retraction was light,the cell survival rates were significantly increased (P<0.01),the activities of LDH,CK and MDA levels were decreased (P<0.01),and the SOD activities were increased (P<0.05 or P<0.01).Conclusion Sch B has protective effect on myocardial cells with H/R injury in the neonatal rats,which may be associated with anti-oxidative damage.关键词
