摘要:

中药制剂养血清脑颗粒具有改善脑微循环,缓解血管痉挛的作用,但其对脑缺血再灌注治疗效果的报道较少。实验以0.3,0.1,0.03 g/mL养血清脑颗粒连续7d灌胃大鼠后,对其进行短暂性大脑中动脉闭塞2h后再灌注,灌胃3或7d。观察显示较高剂量的养血清脑颗粒灌胃的大鼠神经功能明显改善,3d时脑梗死体积减少,损伤脑组织中白细胞介素1β阳性细胞数量减少,白细胞介素10表达增加,7d时血管生长因子阳性细胞数量增加,Ang-1和血管生长因子表达增加,凝血及血液流变指标明显改善。说明养血清脑颗粒对脑缺血再灌注损伤有确切的神经保护作用。

Abstract:

Cerebralcare Granule (CG) improves cerebral microcirculation and relieves vasospasm, but studies investigating its therapeutic effect on
cerebral ischemia/reperfusion injury are lacking. In the present study, we administered CG (0.3, 0.1 and 0.03 g/mL intragastrically) to rats
for 7 consecutive days. We then performed transient occlusion of the middle cerebral artery, followed by reperfusion, and administered CG
daily for a further 3 or 7 days. Compared with no treatment, high-dose CG markedly improved neurological function assessed using the
Bederson and Garcia scales. At 3 days, animals in the high-dose CG group had smaller infarct volumes, greater interleukin-10 expression,
and fewer interleukin-1β-immunoreactive cells than those in the untreated model group. Furthermore, at 7 days, high-dose CG-treated
rats had more vascular endothelial growth factor-immunoreactive cells, elevated angiopoietin-1 and vascular endothelial growth factor expression,
and improved blood coagulation and flow indices compared with untreated model animals. These results suggest that CG exerts
specific neuroprotective effects against cerebral ischemia/reperfusion injury.
