目的:
2
以氧化应激损伤为切入点探讨益气活血方对脑缺血损伤大鼠的保护作用。
方法:
2
将SD大鼠随机分为模型组,假手术组,尼莫地平组(20 mg·kg
-1
),益气活血方高、中、低剂量组(2.916,1.458,0.729 g·kg
-1
),连续灌胃14 d后,采用结扎双侧颈总动脉法建立急性脑缺血损伤模型,透射电镜观察突触超微结构,生化法检测脑匀浆中总超氧化物歧化酶(T-SOD),丙二醛(MDA),乳酸脱氢酶(LDH),谷胱甘肽过氧化物酶(GSH-Px),腺嘌呤核苷三磷酸(ATP)酶的水平,蛋白免疫印迹法(Western blot)和实时荧光定量聚合酶链式反应(Real-time PCR)测定大鼠缺血区脑皮层血红素氧化酶-1(HO-1),核因子E2相关因子2(Nrf2)蛋白和mRNA表达。

Objective:
2
To investigate the protective effect of Yiqi Huoxue recipe on rats with cerebral ischemia injury by using oxidative stress injury as an entry point.
Method:
2
SD rats were randomly divided into model group
sham operation group
nimodipine group (20 mg·kg
-1
)
Yiqi Huoxue recipe high
medium and low dose group (2.916
1.458
0.729 g·kg
-1
). After 14 days of stomach
acute cerebral ischemic injury model was established by ligation of bilateral common carotid arteries. Ultrasound of synapse was observed by transmission electron microscopy. Total superoxide dismutase (T-SOD) and dialdehyde (MDA)
lactate dehydrogenase (LDH)
glutathione peroxidase (GSH-Px)
horizontal adenine nucleoside triphosphate (ATP) levels were detected by biochemical method. Western blot and Real-time PCR was used to determine the expression of heme oxygenase-1(HO-1) and nuclear factor E

-related factor 2 (Nrf2) protein and mRNA in the ischemic cortex of rats.
Result:
2
Transmission electron microscopy showed that Yiqi Huoxue recipe had a significant improvement on the degree of cerebral ischemic injury. Compared with sham operation group
MDA levels in the brain homogenate of model group increased significantly
T-SOD and GSH-Px levels were significantly decreased (

the medium and high dose group of Yiqi Huoxue recipe significantly decreased MDA content in brain tissue and increased the levels of T-SOD and GSH-Px(
