摘要 目的 研究 Carnosine对 β淀粉样蛋白片段 (Aβ2 5- 3 5)诱发 PC1 2细胞损伤的神经保护作用。方法 将培养的 PC1 2细胞分为三组 :正常对照组、损伤组和保护组。损伤组用 Aβ2 5- 3 5处理细胞 ,保护组在用 Aβ2 5- 3 5处理前 30 min加入 Carnosine。使用细胞形态学方法、LDH法、MTT法观察 Carnosine的神经保护作用。结果 通过形态学方法 ,保护组细胞数显著比损伤组多 ,受损变圆的细胞数较少。保护组 LDH活性显著少于损伤组(P<0 .0 1 ) ;MTT显著高于损伤组 (P<0 .0 1 )。结论  Carnosine对 Aβ2 5- 3 5诱发 PC1 2细胞损伤有显著的保护作用。
