摘 要:为探讨关节软骨缺损的修复方法,采用家兔30只,平均分成两组。在每个动物的双侧髌股关节股骨关节面作4mm×7mm全层软骨缺损。将经二步冷冻法保存的胎兔颅骨骨膜移植于一组动物一侧后肢作为实验组,另一侧用自体骨膜移植作为自体对照组。在另一组动物的一侧后肢用新鲜胎兔颅骨骨膜移植作为新鲜对照组,另一侧关节软骨缺损不修复作为空白对照组。术后肢体不作外固定。16周后取材,经大体观察、组织学观察及氨基酸成分分析。结果发现,经冷冻保存的胎兔颅骨骨膜移植后能形成透明样软骨,与自体对照组无显著性差异(P>0.05),与新鲜对照组及空白对照组主要指标有显著性差异(P<0.05)。氨基酸分析示实验组新生物接近纤维软骨(P>0.05)。认为,冷冻胎兔颅骨骨膜移植为关节软骨缺损的修复提供了实验依据。In order to repair cartilage defect in joint with transplantation of cryopreserved homologous embryonic periosteum, 30 rabbits were used and divided into two groups. A 4 mm×7 mm whole thickness cartilage defect was made in the patellar groove of femur of each rabbit. The homologous embryonic rabbit skull periosteum (ERSP), preserved in two-step freezing schedule, was transplanted onto the cartilage defect of joints of one group and autogenous periosteal graft was done in the joint defect of the other group. The knees were not immobilized, following operation and 16 weeks later, the newly formed tissue in the defects were assessed by gross observation, histochemical examination and biochemical analysis. The results showed that new hyaline-like cartilage was formed in the cryopreserved ERSP grafted knee, and had no significant difference from that of the knee receiving autogenous periosteal graft, but had significant difference from that of the fresh ERSP grafted knee and the nongrafted knee. Furthermore, the new hyaline-like cartilage had the biochemical characteristics of a fibrous cartilage. The conclusion was that this method might be feasible to repair articular cartilage defects.
