Study on the Surface Ultrastructure of the Internal Elastic Lamina of Rabbit Aorta
摘要
Abstract
<正> The surface ultrastructure of the internal elastic lamina(IEL)ofrabbit aorta was investigated with scanning electron microscopy(SEM).After fixation of aorta in situ at physiological pressure
the endotheliumwas torn off by using nitrocellulose and the endothelim-free intima wasdigested by HC1 and then treated by Tween.The IEL
covering thetunica media
was carpet-like which consisted of densely populated elas-tic fibers.The Stomata of the IEL were also observed.These stomatawere probably specially differentiated structures and some cells could beseen passing through them.The significance of stomata was discussed.Itwas proposed that SEM was very useful for studying the three-dimens-sional relationship of the IEL.
