| 中文摘要: |
| 用网格交点计数法测量了正常家兔主动脉弓靠近内弹性膜和靠近外弹性膜侧的平滑肌细胞胞质的超微结构。主动脉弓靠内弹性膜侧的平滑肌细胞与靠外弹性膜侧的平滑肌细胞相比，两者的肌丝没有明显的变化，但前者胞质的粗面内质网、线粒体和高尔基复合体明显增多。结果提示：主动脉弓靠内弹性膜侧平滑肌细胞与合成功能相关细胞器增加可能与动脉粥样硬化的发生发展有关。 |
| 英文摘要: |
| In this paper,the phenotypes of smooth muscle cells(SMCs)in aortic media were examined by electromicroscopic study, and the volume fraction of synthetic organelles and myofilaments in SMCs was detemined morphometrically. The results indicated that aortic smooth muscle cells adjoining inter elastic lamina and exter elastic lamina were all contractile phenotype, but the volume fraction of organelles of smooth muscle cells adjoining inter elaster lamina was significumtly increased.There data suggested that the increase of the volume fraction of organelles of smooth muscle cells adjoining inter elastic lamina could related with the formation and development of atherosclerosis. |
