| 摘 要： | 为探讨运动训练对大血管的影响，对长期游泳训练的大鼠主动脉中膜作了透射电镜及光镜的配合观察。结果发现：游泳训练后的大鼠主动脉中膜平滑肌细胞线粒体、粗面内质网、微饮小泡等超微结构产生了形态学上的变化。中膜弹力纤维增多有利于大动脉的弹性贮器功能。为进一步研究运动训练对大血管的影响提供了形态学上的依据。

| Abstract: | The tunicae media of aortae in rats, which had their swimming training for a long time, were observed under transmitted electron microscope and light microscope in order to inquire into the effects of physical training on blood vessels. The results showed that after swimming training the mitochondria in the smooth muscle cells of the tunicae media of aortae, the endoplasmic reticula and the tunicae media of aortae, the endoplasmic reticula and the pinocytolic vesicles in rats had changed morphologically. The increase of tunica media elastic fibers is advantageous to the elastic reservior functions of the conducting arteries. It has provided morphological basis for further researches on the effects of physical training on blood vessels. |
