自由基导致的神经细胞损伤是中风发病机理之一. 多项体外和体内研究证明,通过干预自由基在局部缺血部位导致的细胞凋亡,抗氧化剂可起到神经保护作用,而具有抗氧化功效的自然产品无疑是一种极有潜力的治疗中风的候选药物.奉研究的目的是评估脑必通(Braintone)在Wistar)k2鼠大脑中动脉梗死模型(MCAO)的治疗作用.与对照组相比,脑必通治疗组大鼠促凋亡基凶(AT2受体,FAS,BAX和BCL-XS)的表达量显著地减少(分别是0.4-,0.72-,0.76-,0.32倍,P<0.05).免疫组化结果显示这些基因所对应的蛋白质表达量也大量减少.TUNEL的观察结果进一步验证了脑必通的抗凋亡作用.从而证明脑必通作为一种抗氧化药物,对中风的治疗的确具有一定的潜在功效.“,”Free radical induced neuronal damage is involved in stroke. Several in vitro and in vivo studies have proved that antioxidant could act as neuroprotective agent through intervening with free-radical mediated apoptosis in the ischemic penumbra. In particular, natural products which contain antioxidant properties have undoubtedly potential for stroke treatment. In the present study, therapeutic effects of Braintone on Wistar rats undergone middle cerebral artery occlusion (MCAO) was evaluated. Gene expression levels of pro-apoptotic genes (AT2 receptor, FAS, BAX and BCL-XS) were showed to be significantly reduced in Braintone treated groups (0.4-, 0.72-, 0.76-, 0.32-fold, P<0.05) as compared to vehicle group. Significant reduction of immunoreactivity of protein production of these genes, together with least nuclear green fluorescence observed in TUNEL, Braintone as an antioxidant drug, is concluded to have promising therapeutic effect for stroke treatment.
