摘要: 为观察救脑益智水提液对半乳糖老化小鼠海马神经元的神经元存活信号转导通路和凋亡级联反应中某些蛋白质表达的影响,将昆明种小鼠分为4组(每组24只):正常对照组(C组)、D-半乳糖老化模型组(D组)、大剂量药物治疗组(B组)和小剂量药物治疗组(S组).除C组外,3组小鼠每日皮下注射半乳糖50mg/kg.其中B组和S组每日分别灌胃救脑益智胶囊水提取液,相当于生药1g/kg和0.3g/kg,C组和D组分别灌胃等量生理盐水,共3个月。结果:D组小鼠海马神经元中Akt/PKB(蛋白激酶B)、CREB(cAMP response element binding protein)和Bcl2的免疫组化阳性细胞数明显减少,而AIF(凋亡诱导因子)和Bax明显增加,PP-1(蛋白磷酸酯酶-1)也明显减少。S组上述改变恢复正常,而B组却无此作用。提示:小剂量救脑益智水提液对半乳糖老化模型小鼠海马神经元的存活信号转导通路和凋亡级联反应的改变具有恢复正常的作用,而大剂量则无此作用。

Abstract: The objective of this study was to investigate whether the liquid extract of Jiunaoyizhi capsule has a protective effect on neuronal impairment of the aging mice induced by D-galactose. Several antibodies were applied to detect the immunoreactive positive neurons in hippocampus. It was found that in the D-galactose induced aging mice the Akt/PKB, CREB and Bcl-2 is as well as PP-1 positive neurons decreased obviously, but AIF and Bax increased significantly. The mice treated with 0.3 g/kg liquid extract of raw herbs could make these changes normal. The small dosage of jiunaoyizhi has effect on the impairment of signal pathway of hippocampal neurons in the aging mice. But the unexpected result was that the 1.0 g/kg liquid extract exerted no such effect.

Key words: Jiunaoyizhi capsule, D-galactose induced aging mice, hippocampal neurons, signal pathway
