目的: 研究蒙药额尔顿·乌日勒对血清一氧化氮( NO) 和一氧化氮合成酶( NOS) 在大鼠视网膜缺血
再灌注损伤( RIR) 中的影响,探讨额尔顿·乌日勒对大鼠RIR的保护作用及其相关机制。方法: 通过高眼压法
造成RIR模型,采用ELISA 方法对160 只RIR大鼠血清中NO、NOS 含量进行测定。结果: 视网膜缺血再灌注后
模型组NO 和NOS 含量非常显著地高于空白组( P<0.01) ,12h、24h、48h 高剂量组NO 含量非常显著地低于模型
组( P<0.01) ,24h、48h 低、中剂量组NO 含量显著地低于模型组( P<0.05) ,24h、48h 高剂量组NOS 含量显著地低
于模型组( P<0.05) 。结论: 蒙药额尔敦·乌日勒能降低RIR血清中NO、NOS 含量,能够减轻视网膜组织损伤,
对视网膜缺血再灌注损伤具有保护作用。

[Abstract]
Objective: Study on Mongolian medicine Erdun-wurile on serum nitric oxide( NO) and
nitric oxide synthase( NOS) in rat retinal ischemia and reperfusion( RIR) effects of Erdun -wurile of
RIRinjury protective effects and related mechanisms.Methods: the high intraocular pressure by the
method of RIRmodel,using ELISA method of NO and NOS in serum of 160 RIRrats were determined.
Results: the contents of NO and NOS in retinal ischemia and reperfusion model group were significantly
higher than the control group( P<0.01) , the NO content of 12h, 24h, 48h high dose group was significantly
lower than the model group( P<0.01) , the NO content of the 24h,48h low,middle dose group
was significantly lower than the model group( P<0.05) , the NOS content of the 24h,48h high dose
group was significantly lower than the model group( P<0.05) .Conclusion: Mongolian Medicine Erdunwurile
can reduce the contents of NO and NOS in serum of RIR,can reduce the damage of retina,and
has a protective effect in the retinal ischemia reperfusion injury.
