动脉粥样硬化的扫描电镜(SEM)研究开始于六十年代末期。SEM具有很宽的放大范围(20～100000倍)和高分辨率(60～100A),能在三维结构上观察较大的样品,便于研究血管内表面的概貌和区域性差异,易于发现各种血液成份与血管壁的相互作用。由于可在样品上标记血流方向,有利于研究血流应力与血管内表面结构的关系。因此,近年来SEM已被广泛应用于家兔、鸽、豚鼠、大鼠、狗、猪、猴和人等不同种属的动脉粥样硬化的研究。许
Atherosclerotic scanning electron microscopy (SEM) study began in the late sixties. SEM has a wide range of magnification (20 ~ 100000 times) and high resolution (60 ~ 100A), can be observed in the three-dimensional structure of larger samples for the study of vascular surface profile and regional differences, easy to find a variety of Interaction of blood components with the vessel wall. Because the direction of blood flow can be marked on the sample, it is helpful to study the relationship between blood flow stress and the surface structure of the blood vessel. Therefore, in recent years, SEM has been widely used in studies of atherosclerosis in different species of rabbits, pigeons, guinea pigs, rats, dogs, pigs, monkeys and humans. Xu
