摘要
目的在于观察兔同种胎软骨移植后的不同时期组织和细胞学变化，为临床应用提供可靠依据。所用方法为将妊娠２６天的新鲜兔胎软骨移植到２７只成年同种家兔的面部骨膜下，在不同时期切取标本进行光镜和电镜观察。结果显示，兔胎软骨移植后的生长方式类似于一般软骨间质生长和软骨膜下生长，在移植后半年，兔胎软骨的生长有停止倾向。作者认为，新鲜胎软骨移植可以作为骨诱导材料和支架材料供临床使用。
Purpose:In order to provide reliable basis for clinical application of rabbit fetal cartilage allografts,histological and cytological changes were observed after their transplanting.Method:Fresh rabbit cartilage allografts from the fetal rabbits of 26 days were transplanted under the periosteum in rabbit faces of 27 grown up rabbits.Samples from different periods were observed under light and transmission electron microscope.Result:The way of growth after the fetal cartilage allografts was similar to the normal appositional and interstitial growth.Growth tends to stop after the 6th month of grafting.Conclusion:Fresh fetal cartilage allografts can grow after transplanting till the 6th month. They can clinically be used as grafting material.
