本实验采用0.5％福尔马林溶液处理异体骨,并与新鲜自体骨同时在狗的下颌骨移植,分别在术后1、2、4、8、14、24周进行X线、组织学观察、于2、4、8周进行四环素荧光、透射电镜观察,结果表明0.5％福尔马林溶液可有效地降低异体骨的抗原性,异体骨移植后未引起宿主产生明显的免疫排斥反应,其成骨方式与自体骨完全相同,但新骨出现晚于自体骨,骨改建过程也比自体骨缓慢。 In this experiment, 0.5% formalin solution treatment of allogeneic bone, and fresh autologous bone at the same time in the dog's mandible transplantation, respectively, at 1,2,4,8,14,24 weeks after X-ray, histological observation , Tetracycline fluorescence and transmission electron microscopy were performed at 2,4,8 weeks. The results showed that 0.5% formalin could effectively reduce the antigenicity of allogeneic bone, and did not cause obvious immune rejection after allograft Osteoblasts are identical to autologous bone, but new bone appears later than autologous bone, and bone remodeling is slower than autologous bone.
