摘要: 目的 研究9-(4-乙氧羰基苯氧基)-6, 7-二甲氧基-1, 2, 3, 4-四氢吖啶盐酸盐(EDT) 对神经细胞缺血缺氧损伤的影响。方法 离体培养的PC12 细胞, 用连二亚硫酸钠造成缺氧/复氧损伤模型, 用NaCN 加缺糖造成拟缺血损伤模型, 通过MT T 微量比色、培养介质LDH 活力测定研究EDT 对两模型的保护作用。结果 在10-8~10-6 mol·L-1范围内, EDT 浓度依赖地降低两种损伤所致培养介质内LDH 的释放, 增加MTT 比色值, 同时10-6 mol·L-1 EDT 对两模型的保护作用具有时间依赖性, 48 h 达效应平台。结论 EDT 对PC12 细胞缺血缺氧损伤具有保护作用。

Abstract: 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 Na2S2O4 and 20 mmol·L-1 NaCN in combination with glucose deprivation.The pro tective effects of EDT on these two models were evaluated by lactate dehydrogenate (LDH) ef flux assay and colormetric MT T assay.Results EDT, 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 concent ration-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.
