Résumé
Aim To investigate the effects of EDT on anoxia and ischemic injury in cultured PC12 cells. Methods Cultured PC12 cells were treated with 1 mmol?L -1 Na 2S 2O 4 and 20 mmol?L -1 NaCN in combination with glucose deprivation. The protective effects of EDT on these two models were evaluated by lactate dehydrogenate (LDH) efflux assay and colormetric MTT assay.ResultsEDT, within the range of 10 -8～ 10 -6 mol?L -1, significantly antagonized LDH efflux induced by two models and increased the optical density at 570 nm tested by colorimetric MTT assay in concentration-dependent manner. 10 -6 mol?L -1 EDT might time-dependently inhibit two injuries and reach maximal level at 48 h. Conclusion EDT can protect PC12 cells from anoxia and ischemic injury.
Résumé
Objective To investigate the effects of the serum contained Shuluo sterile powder for injection (SLI) on injury induced by anoxia and hypoglycemia in cultured PC12 cells. Methods Cultured PC12 cells were treated with Na2S2O4 and Earle′ s liquid with glucose free to induce models of anoxia and hypoglycemia. The protective effects of the serum contained SLI on the two kinds of models were evaluated by the activity of lactate dehydrogenate (LDH) and staining with MTT assay. Results The serum contained SLI counteracted the injury induced by anoxia and hypoglycemia to various degrees and prevent the efflux of LDH. Conclusion The serum contained SLI can protect PC12 cells from injury induced by anoxia and hypoglycemia.
