摘要 目的探讨丹参注射液对兔视网膜缺血再灌注损伤视网膜节细胞凋亡和caspase-3表达的影响。方法在建立兔视网膜缺血再灌注损伤模型前30 min,首先进行左眼球后注射平衡盐溶液(对照组),右眼球后注射丹参注射液(治疗组)。30 min后通过升高眼内压造成视网膜缺血后,再恢复正常眼内压而制作成兔视网膜缺血再灌注损伤动物模型,分别于1、6、24 h和72 h处死动物,取视网膜,部分视网膜切片行Tunel染色,部分视网膜采用免疫组化法检测视网膜节细胞相关基因caspase-3蛋白的表达。结果除1 h组外,同一时间点对照组视网膜节细胞凋亡计数和治疗组比较,差异具有统计学意义。除1 h组外,同一时间点对照组cas-pase-3蛋白表达与治疗组比较差异均有统计学意义。结论球后注射丹参注射液能够减少视网膜缺血再灌注后视网膜节细胞的凋亡,降低caspase-3蛋白表达。
