气管的低温保存和临床移植研究

Studies on Cryopreservation and Clinic Transplantation of Trachea

气管是个机构复杂的器官，其中纤毛更具有特殊的功能。为满足临床气管移植的需要，本文研究了气管的低温保存工艺和移植技术。本研究探索得到的气管低温保存工艺方法，经电镜分析显示，气管的超微结构和纤毛的功能均得到很好保存。对２０只狗进行移植试验，除３只因移植物气管软化和狭窄的死亡外，存活率达８０％；对人的临床低温保存和移植试验进行了２例，也取得很好的效果。

In order to meet the need of clinic application,the methods of trachea cryopreservation and transplantation are studied.Evaluation by electron microscopy shows that the ultrastracture of cryopreserved trachea are very similar to the fresh one,and the cilia have normal function.Transplantation studies show eighty percent(17/20) of dogs were survival.And also 2 cases of human transplantation with cryopreserved trachea are successful.
