针刺对急性脑出血模型大鼠局部脑血流量的影响

Effect of Acupuncture on Cerebral Blood Flow of Acute Cerebral Hemorrhage Model Rats

目的:动态观察急性脑出血模型大鼠出血半球脑表面血流量的变化规律及针刺效应。方法:应用激光多普勒血流监测仪分别动态观察治疗组、对照组及模型组急性脑出血模型大鼠出血半球脑表面血流量。结果:脑出血后,模型组脑表面血流量大幅下降,与正常组、对照组和治疗组比较,差异有显著性(P<0.05或P<0.01)。且治疗组在增加局部脑血流量方面明显优于对照组,差异有显著性(P<0.05)。结论:针刺能显著增加急性脑出血后脑局部血流量,一定程度上阻止了因局部脑血流降低而引发的一系列病理现象,对保护脑细胞,避免脑细胞损害均起了积极的作用。

Objective: To investigate dynamically change of cerebral superficial volume of blood flow in the cerebral surface of the hemorrhage hemisphere in the acute cerebral hemorrage model rat and effects of acupuncture. Methods: Blood flow of the cerebral surace in the breeding hemisphere in acute cerebral bleeding model rat were investigated by laser doppler blood flow monitor in treatment group. control group and medel group. Results: After cerebral hemorrage. blood flow in cerebral superface decreased largely with a significant difference as compared with the normal group. control group and treatment group. Treatment group was significantly superior to control group in increase of blood flow in the local brain (P<0. 05). Conclusion: Acupuncture can significantly increase volume of blood flow in the local brain after acute hemorrhage. and arrest a series of pathological phenomena induced by local decrease of cerebral volume of blood flow to a certain extent.
