针刺对实验性脑缺血家兔超微结构的影响

目的：探讨缺血性脑血管病（ＩＣＶＤ）的发病机理，同地结合现代是论为临床针灸治疗缺血提供客观理论依据。方法：运用“三血管”阻断法，以家兔为研究对象，建立了实验性不完全性脑缺血模型，采有“醒脑开窍”针法施以治疗，定性观测大脑皮质超同结构的改变，运用形态学计量法定量观测细胞核和线粒体体密度以及突触间隙。结果：针刺能明显改善脑缺血家兔的大脑皮质超微结构、线粒体、粗面内质网、高 在体破坏程度及核膜凹陷各度明

THE EFFECT OF ACUPUNCTURING ON ULTRASTRUCTURE OF ICVD IN EXPERIMENTAL RABBIT

Objective: This experiment is to study the mechanism of ICVD and to provide the objective basis for clinically treating ICVD after acupucturing. Method:Occluding CCA and left vettebral artery, 3-vo ICVD models in rabbits weremade. The influences on ultrastructure of cerebral cortex by acupucturing Ren Zhong, Nei Guan and San Yin Jiao points were observed. Results: ultrastructure of cerebral cortex in ICVD rabbits were improved greatly. Compared with model groups, observation on the acupuncturing groups showed that the demage of mitochondrion, rough endoplasmic reticulm and meclede became less. The results of dimensional puantitative analysis showed that there was significant differance between the model group and acupuncturing group in dimensi onal density of mitochondrions, necledes and synapse space. Conclusion:Acupuncturing can lessen the cerebral demage caused by ischemia.
