目的：研究电针对急性出血性低血压的大鼠软脑膜微循环的作用。方法：通过股动脉放血造成急性低血压的模型，经过开颅术后在软脑上安置颅窗，利用荧光显微镜观察软脑膜微循环和显微图像，我们分析了针刺过程对脑小动脉的作用。结果：电针前三里有增加脑血流的作用。血压（设ｙ为相对平均血压）－小动脉管径（设ｘ为相对直径）相互关系由以下公式描述：针刺组：ｙ＝１．３２８ ５ｘ~２．２ ８７６ ３ｘ＋ ２．４９３１，非针刺组；ｙ＝０．４７６ ６ ｘ~２－ ０．９７６ ２ｘ＋１．５０８ ４。结论：电针对急性出血性低血压的大鼠软脑膜微循环有明显的扩张小动脉血管的作用。
Objective: To study the effect of electroacupuncture on pia mater microcirculation in rats with acute hemorrhagic hypotension. Methods: A model of acute hypotension caused by the blond of the femoral artery was used. After craniotomy, the cranial window was placed on the soft brain. The microcirculation and microscopic images of the cerebral plexus were observed by fluorescence microscopy. effect. Results: Electroacupuncture first three years to increase the role of cerebral blood flow. Blood pressure (let y be the mean blood pressure) - the diameter of the arterioles (x is the relative diameter) The correlation is described by the following formula: Acupuncture group: y = 1.328 5x ~ 2.2 876 3x + 2.4931, Thorn group; y = 0.476 6 x ~ 2- 0.976 2x + 1.508 4. Conclusion: Electroacupuncture can significantly promote the arterioles in the pia mater microcirculation of rats with acute hemorrhagic hypotension.
