本文对用透明质酸酶消化去除糖胺聚糖后的大鼠透明软骨和纤维软骨进行了超微结构观察，并与弹性系统纤维选择性染色切片进行了光镜观察。除气管透明软骨软骨膜内纤维层可见弹性纤维外，其余软骨均未见弹性纤维。然而，软骨组织中含有oxytalan和elaunin纤维。上述弹性纤维在两种软骨中都有明显的分布。透明软骨在包围软骨细胞的细胞外基质中具有oxytalan纤维，而弹性纤维位于包围软骨的软骨膜的纤维层中。在软骨膜附近的过渡（软骨形成）层中可以检测到Elaunin纤维。所使用的方法公开了在纤维软骨中存在沿胶原束的外周沿着延伸的oxytalan和elaunin纤维。
Rat hyaline and fibrous cartilages whose glycosaminoglycans had been removed by hyaluronidase digestion were studied by comparing the ultrastructural features with the observation of sections stained by selective methods for elastic system fibers under the light microscope. Except for the fibrous layer in the perichondrium of tracheal hyaline cartilage, where elastic fibers were found, no elastic fibers could be detected in the cartilages studied. However, cartilaginous tissues contained oxytalan and elaunin fibers. A distinct pattern of distribution of the above-mentioned elastic-related fibers could be observed in both kinds of cartilages. Hyaline cartilages possess oxytalan fibers in the extracellular matrix that surrounds the chondrocytes, whereas elastic fibers were localized in the fibrous layer of the perichondrium that encloses the cartilage. Elaunin fibers could be detected in the transition (chondrogenic) layer adjacent to the perichondrium. The methods used disclosed the presence of oxytalan and elaunin fibers running along the periphery of the collagen bundles in fibrocartilage.
