2.Qingguangking could decrease the level of edema in retina of acute ocular hypertension
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:
l-n培increasing expression of HIF-la in retina in rats of acute elevation in intraocular pressure sustained the theory ofhypoxin in damage ofoptic nerve of glaLI∞m丸
