The vascular supply to the proximal tibial growth plate of the 7 weeks old chicken is described using various vascular markers. In addition the ultrastructure of metaphyseal and epiphyseal vessels as well as their supporting tissue is reported. The metaphyseal arterioles terminate in large calibre vessels which have occasional endothelial gaps and no basement membrane or supporting cells, and therefore could be classified as venous sinusoids. In contrast the epiphyseal arteriole terminates in a capillary-venule plexus lined by an attenuated and fenestrated but continuous endothelium. This paper definitively establishes that communication of epiphyseal and metaphyseal vessels across the avian growth plate does not occur. The eosinophilic streaks which often join these two vascular supplies have been described ultrastructurally and would appear to be remnants of the 'retreating' epiphyseal vessels.
运用多种血管标记物描述了7周龄鸡胫骨近端生长板的血管供应情况。此外，还报告了干骺端和骨骺端血管及其支持组织的超微结构。干骺端小动脉终止于大口径血管，这些血管偶尔存在内皮间隙，没有基底膜或支持细胞，因此可归类为静脉血窦。相比之下，骨骺端小动脉终止于由变薄且有窗孔但连续的内皮细胞衬里的毛细血管-小静脉丛。本文明确证实，禽类生长板两端的骨骺端和干骺端血管之间不存在连通。经常连接这两种血管供应的嗜酸性条纹已通过超微结构进行了描述，似乎是“退缩”的骨骺端血管的残余物。
