摘　　要：目的 :研究骨骺软骨管的形态结构。方法 :胎儿和新生儿胫骨近端骨骺标本 ,用组化染色方法及电镜观察。结果 :胎儿 8周时无软骨管 ,14周软骨管数目少 ,2 2周增多 ,2 9周最多 ,分支复杂 ,新生儿软骨管数目减少。软骨管除由动脉、静脉和毛细血管 ,还包含淋巴管。结论 :胎儿胫骨近端骨骺软骨中存在淋巴管 ,淋巴管是软骨管的重要组成成分。Objective: To study morphological structure of cartilage canals of epiphysis .Methods:The tissue specimens of proximal tibial epiphyseal cartilage obtained from fetus and neonates were examined by histologic method (HE) and modified histochemical method and transmission electron microscopy.Results:Cartilage canals which grew into epiphyses from perichondrium or cruciate ligaments were found at 14 wk,increased at 22 wk and developed fully at 29 wk of gestation.With the formation of secondary ossification center,the quantity of cartilage canals decreased.In addition to arteries,veins and blood capillaries,cartilage canals were also composed of lymph capillaries.Conclusion:Epiphysis cartilage of proximal tibial of fetus contained lymphatic vessles which were an important component of the cartilage canals.
