目的:观察功能性电刺激(FES)治疗对急性脑梗死大鼠运动功能和缺血半影区微管相关蛋白-2(MAP-2)表达的影响。方法:制作急性大脑中动脉栓塞模型大鼠。随机分为假手术组、FES安慰治疗组和FES治疗组共三组,每组又分为治疗0d、3d、7d、14d四个亚组,每亚组共6只,术后3天开始FES治疗。FES治疗引起瘫痪侧伸腕伸指动作,每天1次,每次10min。在治疗前和治疗后的各个时间点采用网屏试验评定运动功能,评定后取材,应用免疫组化技术观察半影区MAP-2变化。结果:治疗7d和14d后,FES治疗组的运动功能 |

Abstract: |
Objective: To observe the effects of functional electrical stimulation (FES) on motor function and the expression of microtube-associated protein 2 (MAP-2) in the penumbra field of the rats with acute cerebral infarction. Method:Acute cerebral infarction was made by means of middle cerebral artery occlusion. Rats were randomly divided into sham-operated, FES placebo-treatment and FES treatment groups. Each group was divided into 0-day, 3-day, 7-day and 14-day subgroups and 6 rats for each subgroup. FES treatment to induce wrist and fingers extension was carried out 3 days after operation and was performed once daily, 10 minutes each time. The motor function and protein expression of MAP-2 were observed before treatment and at each treatment points. Result:After treatment for 7 days and 14 days, the motor function of FES treatment group was significantly improved, comparing with that of FES sham-treatment group (P<0.05), and the MAP-2 labeled cells and expression were also significantly enhanced comparing with that of the FES sham-treatment group (P<0.01). Conclusion:FES treatment can improve motor function and enhance the expression of MAP-2 in the penumbra field of the rats with acute cerebral infarction. |
