So study on bone tissue engineering are becoming one of the hot points in the field of Orthopaedic research.

而机体产生的排异反应，疾病传播的可能性和骨不愈合等并发症又使异种骨移植的应用受到限制，所以对组织工程化骨组织的研究成为目前骨科研究的热点之一。

Posterolateral Lumbar Intertransverse Process Spinal Arthrodesis With Composites Composed Of Recombinant Human Bone Morphogenetic Protein 2 And Allograft Or Xenograft; Or With Composite Consisted Of HA And Xenograft in rabbitsBackground: So far spine arthrodesis remains to be used in spine surgery.

中文题名rhBMP-2、HA及其复合物在兔腰椎后外侧融合的实验研究副题名外文题名论文作者杨发军导师马忠泰教授学科专业外科学研究领域\研究方向临床技能训练与研究学位级别博士学位授予单位北京大学学位授予日期2001 论文页码总数92页关键词骨形态发生蛋白异体骨移植脊柱融合异种骨移植馆藏号BSLW /2001 /R687 /42 背景：目前，脊柱融合手术被广泛地应用于脊柱外科领域，自体髂骨仍是被最常用的骨移植物，但是其有5％-35％的不融合率。

RESULTS ① rhBMP2/BCB used alone was capable of healing the defect in large part by 16 wk, with a similar repair process and mechanism to that seen with RBX;② use of rhBMP2/BCB in conjunction with vascularized periosteal graft exhibited stronger defect-repairing power, basically healing the defect by 8 wk. The repair process consisted of intramembranous and endochondral ossification that resembled the physiological repair during the fracture healing.

结果①单纯rhBMP2/BCB移植，可在16 wk使节段性骨缺损基本修复，其机制与过程与重组合异种骨相似；②rhBMP2/BCB与带血循骨膜联合移植，仅用8 wk即可修复骨缺损，其修复机制与骨折修复相仿，包括膜内成骨和软骨成骨两种机制。

Objective To develop a new small-caliber vascular xenograft and evaluate the feasibility of xenogenic artery for coronary artery bypass grafting.
