摘要
目的探讨盐酸戊乙奎醚(长托宁)对癫痫持续状态(SE)后大鼠海马晚期糖基化终末产物受体(RAGE)和核因子KB(NF—KB)的影响。方法SD大鼠随机分为A组(对照组)、B组(模型组)和c组(盐酸戊乙奎醚组),每组8只。应用氯化锂-匹罗卡品制备SE模型。TUNEL法检测大鼠海马细胞凋亡,Westernblot法检测大鼠海马RAGE及NF—KB065的表达改变情况。结果与A组比较,B组大鼠海马RAGE、NF—KBp65水平明显增高,神经元凋亡增加(P〈0.01);与B组比较,C组大鼠海马RAGE、NF—KBp65水平降低,神经元凋亡减少(P〈0.01)。结论盐酸戊乙奎醚可抑制RAGE—NF—KB通路和减少神经元凋亡,对SE后大鼠海马神经元发挥保护作用。
Objective To investigate the effect of penequinine hydrochloride on the expression of RAGE and NF - kB in rat hippocampal neurons after status epilepticus. Methods Male SD rats were randomly divided into three groups, ie. a control group, a status epilepticus group and a penequinine hydroehloride group (n = 8 each). The rats abdominal cavity of status epileptieus group were injected lithium - pilecarpine to establish status epileptieus model. The expression of RAGE and nuclear factor kappa B ( NF - KB) p65 in hippoeampal was measured by Western blot. TUNEL assay was used merely to identify apoptotie cells. Results Compared with the control group, the expression of RAGE and NF - KB 1365 was significantly higher in status epilepticus group and apoptotie cells were significant increased (P 〈 0.01 ). Com- pared with the status epilepticus group, the expression of RAGE and NF - KB p65 was significantly lower and apoptotie cells were decreased in penequinine hydroehloride group ( P 〈 0.01 ). Conclusion Penequinine hydroehloride shows a protective effects on rat hippocampal neurons after status epilepticus through inhibiting the expression of RAGE and NF - kB.
