摘要 目的本文应用大鼠视网膜缺血再灌注损伤模型,探讨富氢生理盐水对其是否具有神经保护作用。方法成年雄性SD大鼠随机分为4组:正常组、视网膜缺血再灌注组(RIR)、富氢生理盐水组(HRS)、生理盐水组(NS)。正常组大鼠不进行任何手术操作,其他3组大鼠均行前房穿刺,造成缺血60min后恢复灌注,RIR组期间不给予任何干预措施,HRS组和NS组于再灌注前10min及再灌注开始时分别腹腔内注射3m LHRS或2m L NS。应用免疫组化法观察缺血再灌注损伤视网膜神经节细胞存活情况,另外用相应试剂盒检测再灌注24h及7d后大鼠血清中SOD活性及MDA水平。结果缺血再灌注7d后,RIR组大鼠神经节细胞数明显减少(P<0.01),而HRS组视网膜神经节细胞数明显较多(P<0.05);另外,与正常组相比,RIR组SOD活性明显降低(P<0.01),MDA水平明显升高(24h P<0.05,7d P<0.01),与RIR组相比,HRS组SOD活性显著增加(24h P<0.05,7d P<0.01),7d时MDA含量显著降低(P<0.01)。结论腹腔内注射富氢生理盐水能够明显减少神经节细胞凋亡,并可显著提高血清中内源性抗氧化酶活性,降低氧化产物水平。
