为探讨动脉粥样硬化斑块发生中平滑肌细胞的作用,我们以每只兔每日喂饲一克纯胆固醇致动脉粥样硬化斑块形成,取主动脉斑块常规制备标本,透射电镜观察。 对照组家兔主动脉,狭窄的内皮下层中只有少量弹力及胶原纤维,偶见平滑肌细 To explore the role of atherosclerotic plaque in the development of smooth muscle cells, we fed one gram of pure cholesterol per animal per day to induce the formation of atherosclerotic plaque. Specimens of aorta plaques were routinely prepared and examined by transmission electron microscopy. In the control group, there was only a small amount of elasticity and collagen fibers in the aorta and stenosis of the rabbit aorta, occasionally smooth muscle
