摘要
目的 :研究血管束植入后 ,预构组织瓣中移植软骨细胞酶活性的变化 ,探讨预构软骨皮瓣的启动时机。方法 :选用 2 4只新西兰白兔 ,将左耳中央动、静脉束及带软骨膜的软骨植于额顶部皮瓣下 ,并应用酶组织化学技术、血管墨汁灌注等实验手段 ,观察移植软骨细胞酶活性在移植早期的改变。结果 :随着时间的推移 ,移植软骨在经历细胞代谢由低到高的变化过程后 ,当血运重新建立时 ,软骨膜下出现成软骨现象。结论 :血管束植入后 5～ 6周 ,新生软骨细胞趋于成熟 。
Objective: The study was to observe the best time to elevate the neovascularized cutaneous cartilage flaps. Methods: Prefabricated cutaneous cartilage flaps were constructed in 24 rabbits. The process of neovascularization and the formation of cartilage was studied by carbon ink perfusion, histological sections on histochemical stainings of SDH.Results: New cartilage was formed with the neovascularization.Conclusion: The prefabricated cutaneous cartilage flap can be elevated on the 5th or 6th week when the new cartilage cells become matural.
