摘要: 目的 观察葛根素对新西兰白兔视网膜缺血/再灌注损伤组织中细胞凋亡的保护作用。方法 新西兰白兔30只随机分为缺血再灌注对照组和葛根素治疗实验组,各组右眼应用前房灌注加压法建立视网膜缺血再灌注模型,分别于再灌注后第12、24、72 h处死动物,摘除眼球,制作石蜡切片,用TUNEL法检测细胞凋亡,计算凋亡指数。结果 对照组缺血再灌注12 h在神经节细胞层和内核层可见凋亡细胞;24 h神经节细胞层细胞数有所减少,视网膜神经节细胞层、内核层及外核层均见凋亡细胞明显增多;72 h神经节细胞层细胞数明显减少,神经节细胞层、内核层及外核层仍见凋亡细胞,但较24 h有所减少。葛根素治疗视网膜的凋亡细胞在各个时间段的表达规律与对照组相似,但凋亡细胞计数在12 h,24 h,72 h均较对照组明显减少,两组间差异有统计学意义。结论 葛根素能减轻缺血-再灌注损伤的视网膜细胞凋亡,对视网膜有保护作用。

Abstract: Objective To observe the protective effects of Puerarin on apoptosis of ischemic injury in rabbit retina. Methods Retinal ischemia was induced in rabbits by increasing intraocular pressure to 120 mmHg for 60 minutes. TdT-mediated biotin-dUTP nick end labelling(TUNEL) staining technique was used to examine the apoptosis of retinal ganglion cells in the control group and the puerarin treatment group. Results The number of apoptotic cells in 12, 24 and 72h after reperfusion in the puerarin treatment group was obvious lower than that in the control group(P<0.05). Conclusion Puerarin has protective effects in protecting against apoptosis in ischemia reperfusion injury of rabbit retina.
