[目的] 探讨参附注射液对局灶性脑缺血大鼠Na-K-Cl协同转运蛋白1(NKCC1)的影响。[方法] 雄性SD大鼠随机分为假手术组(Sham),缺血模型组(Ischemia)和缺血后给予参附注射液治疗组(SFI).利用线栓法制作脑缺血/再灌注模型,再灌注3 h及24 h后进行神经功能评分,再灌注24 h后2,3,5氯化三苯基四氮唑蓝(TTC)法比较脑梗死面积,免疫组织化学及蛋白印迹法检测NKCC1的表达。[结果] 参附注射液治疗组的脑梗死面积、神经功能缺损程度均比对照组明显降低(P<0.05).和对照组相比,SFI组的NKCC1表达明显低于Ischemia组(P<0.05).[结论] 参附注射液对大鼠脑缺血模型的神经保护作用可能与抑制NKCC1相关。 |

Abstract: |
[Objective] To investigate the effect of Shenfu injection on the expression of Na-K-Cl-cotransporter 1 (NKCC1) in rats with focal cerebral ischemic stroke. [Methods] The ischemic stroke was generated by 90 min occlusion of right middle cerebral artery. After 24 h reperfusion, neurological score was evaluated. The cerebral infarct volumes were quantified by 2, 3, 4-triphenytetrazolium-chloride (TTC), and the NKCC1expression were evaluated by Western blot and immunofluorescence methods. [Results] Shenfu injection-treatment group (SFI) significantly reduced the infarct volume (P<0.05) and the degree of neurological deficits (P<0.05). Compared to the ischemia group, the protein expression of NKCC1 was significantly reduced in the SFI group. [Conclusion] Shenfu injection plays a neuroprotective role in rats with experimental cerebral ischemia, which was associated with the inhibition of NKCC1. |
