目的:验证两种不同来源的ADM(脱细胞真皮基质)材料作为屏障膜引导骨再生(Guided Bone Regeneration,GBR)的效果。方法:取新西兰大白兔20只,分别在其颅顶矢状缝左右各建立一个直径8 mm的骨缺损区;然后按观察时间随机分为8周、12周两大组,每一大组各随机分为5个亚组(n=4);A组缺损中植入HA-TCP(羟基磷灰石-磷酸钙双相复合骨替代材料)+P-ADM膜(猪脱细胞真皮基质),B组植入HA-TCP+B-ADM膜(牛脱细胞真皮基质),C 组植入 HA-TCP +胶原膜(Bio-gide 胶原膜),D 组只植入HA-TCP,E组不放置任何材料。分别于术后8、12周处死相应组大白兔,切取骨缺损区标本并制作组织切片,采用HE染色和马松(Masson)染色法定量分析各组骨缺损区骨组织再生的情况。结果:P-ADM、B-ADM在GBR技术中均能发挥屏障膜作用,引导和促进兔颅骨组织再生,其中B组与C组相比,在8周和12周时的成骨效果均无显著性差异(P>0.05);而A组在8周和12周时的成骨效果均显著低于B、C两组(P<0.05),但明显高于D、E两组(P<0.05)。结论:猪、牛两种来源的ADM材料在GBR技术中均能发挥屏障膜作用,并能引导骨缺损区的骨组织再生。

AIM:To compare the effects of two acellular dermal matrix (ADM)materials on the repair of the rabbit skull defects.METHODS:A cycloid skull defect with the diameter of 8mm was made on both sides of the sagittal suture of 20 rabbits.The rabbits were randomly divided into 5 groups.The skull defects were treated with im-plantation of hydroxyapatite-tricalcium phosphate (HA-TCP)+porcine ADM (P-ADM ),HA-TCP +bovine ADM (B-ADM,Haoao Biofilm ),HA-TCP +Bio-gide collagen membrane,HA-TCP and wihtout implantation (control) respectively.After 8 and 12 weeks,10 rabbits were sacrificed respectively and the bone samples were were examined by HE staining and Masson staining.RESULTS:Both P-ADM and B-ADM could play a role as barrier membrane in guiding and promoting osteogenesis in rabbit skull defects.There was no significant difference between B-ADMand Bio-gide collagen membrane in promoting osteogenesis at 8 and 12 weeks after treatment(P>0.05).P-ADMimplanta-tion produced less osteogenesis than B-ADM and Bio-gide at 8 and 12 weeks after treatment(P<0.05 ),but more than HA-TCP and control(P<0.05).CONCLUSION:Both P-ADMand B-ADMcan promote osteogenesis in bone defect.
