关于动脉硬化现象的研究,已从形态学和生物化学方面有所进展,丰富了临床和治疗的知识。而对脑动脉尤其是生理和临床重要的脑微动脉硬化问题,尚未得到深入研究。病理学一般认为,人脑出血部位是直径200μm左右的动脉,而对直径15～50μm的血管通常不够重视。得是,这种微血管以及毛细血管直接供给脑组织以营养,其硬化与其分布下的脑功能关系十分密切。微血管出现硬化,管腔变窄,即使不发生出血与栓塞,也可导致脑功能障碍。也可以说,血管性痴呆症就是这种微血管变窄的结果。就脑微血管形态学的特点而言,与身体其他部位的微血管不同,是由一种我们命名为特异的FGP
Research on the phenomenon of atherosclerosis has made morphological and biochemical advances and enriched clinical and therapeutic knowledge. The cerebral artery, especially physiologically and clinically important brain micro-arteriosclerosis, has not been studied in depth. Pathology is generally believed that the site of human cerebral hemorrhage is about 200μm in diameter of the artery, while the diameter of 15 ~ 50μm of the blood vessels are usually not enough attention. To be sure, this kind of capillaries and capillaries directly supply nutrients to the brain tissue, and its sclerosis is closely related to the brain function under its distribution. Microvessel sclerosis, lumen narrowing, even without bleeding and embolism, can also lead to brain dysfunction. Can also be said that vascular dementia is the result of this microvascular narrowing. In terms of the characteristics of cerebral microvascular morphology, unlike the microvessels in other parts of the body, it is composed of a type of FGP
