摘　　要：在22只家兔下颌骨体部的两侧,进行复合胚胎骨移植实验手术44例,用牙钻造成0.7×0.5×0.3cm^3的缺损后。植入7类下同的复合和单纯胚胎骨材料。观察发现复合同种胚胎骨和单纯胚胎骨均有较好的生物相容性和促进骨生长作用。高温高压清毒潜代60Co 消毒胚胎骨,进行移植,也有较好效果。Forty-four transplant operations were perfomed on both sides of the body ofthe mandible in 22 rabbits.Seven types of complex and simple embryo-bones fromrabbits ware placed into holes(0.7×0.5×0.3cm^3)made in the mandibles with adental drill.At the same time,40 pieces of embryo-bones were embedded intoerector spinae muscles of rabbits as control.The specimens were collected at dif-ferent periods after the operations.The transplanted bone was prepared for examin-ation by X-ray,light microscpy,fluorescent microscopy,and transmission electronmicroscopy.Both complex and simple embryo-bones had good biocompatibility andshowed progressive growth.When bones from embryos were sterilized with highpressure and high temperature instead of ^(60)Co,the embryo-bone transplantationswere also successful.
