方法;(1)Wistar大鼠90只随机分为正常对照组A、模型对照组B、青光灵大剂量 组C、青光灵中剂量组D、青光灵小剂量组E和益脉康组F,每组各15只。(2)造模前A、 B组用生理盐水,C-E组用相应剂量的青光灵悬浊液,F组用益脉康悬浊液灌胃,一日两 次,灌胃7天。(3)灌胃7天后B-F组麻醉大鼠,用生理盐水进行前房灌注制作急性高眼 压模型,使眼压达120cmHzO,维持lh,A组不灌注作为正常对照。(4)在造模后,各组 继续用相应药物灌胃,每组随机于1d、2d、3d、7d、14d各处理3只大鼠(每小组6只眼), 取出眼球,制作跟杯,中性甲醛固定、石蜡包埋。(5)石蜡切片做HE染色及HIF-Ia免疫 组织化学染色。(6)观察各组视网膜各层厚度变化情况及HIF·la表达情况,并观察视网膜 的病理组织学改变.

结果:(1)形态学结果示,青光灵中剂量用药组病理组织学改变及水肿轻于模型对照 组。(2)免疫组织化学结果:正常对照组,几乎检测不到HIFola的表达。在模型组,HIF·la 表达量增加.在2d,HIF-Ia表达达到高峰,以后表达量逐渐减少。青光灵用药组与模型对 照组比较HIFola表达量明显有显著性差异(p<O.05),且低于模型对照组。源自’Conclusions:
