Poly ( l - lactic acid ) ( plla ) is the most typical biodegradable polymer used in bone tissue engineering 聚乳酸plla是组织工程中常用的支架备选材料，具有很好的生物相容性。
What are the causes ? our bone is a dynamic organ . new bone tissue is being made while old bone tissue is being broken down 骨骼是一个动态的器官，身体会不停制造新的骨组织，而旧的骨组织会被分解及取代。
Evaluation on the biological performance of poly lactic acid glycolic acid asparagic acid - co - polyethylene glycol tri - block copolymer in vivo as bone tissue engineered scaffold 三嵌段高分子骨组织工程支架材料的体内生物学性能评价
Bioactive substance such as hydroxyapatite ( ha ) and bioglass are coated on their surfaces in order to improve the bond between the implants and bone tissue 为改善其植入后与骨组织的结合，常在其表面涂覆一层具有生物活性的物质，如羟基磷灰石和生物玻璃等。
Bone tissue engineering is the most active field in research of tissue engineering and one of its studies is focused on the preparation of the ideal scaffold 摘要骨组织工程的研究是组织工程最为活跃的领域之一，如何制备理想的骨支架材料是当前的一个研究热点。
This paper systematically reviewed the relevant research advances and applications , and showed the applied prospect of bone tissue engineering in this field 作者系统回顾了近年来一些下领骨缺损修复方法的研究和应用情况,并阐述了组织工程化骨在:这方面的应用前景。
The goal is to come up with a substitute for bone tissue that can put the bone right and regenerate in such a way that it carries out similar functions as in its natural state 目标是达到骨组织替代物的要求? ?可校正骨骼以及促进骨再生，与自然状态下组织的功能相似。
This paper reviews both the advantages and disadvantages of many kinds of scaffolds , compares their mechanical properties and also previews the feature trend of bone tissue engineering 综述了各类骨组织工程支架材料的优缺点，对比了它们的力学性能，开对骨组织工程的前景近行了展望。
During childhood , teen years and early adulthood , new bone tissue is added faster than existing bone is absorbed . as a result , bones become larger and heavier until about age 30 when peak bone mass is reached 儿童时期青春期和成年后的早期新骨的生成大于现有骨骼的吸收，骨骼越长越大，骨质也越来越密，
When human body suffer from suddenness , the material character of skeleton and the mechanical properties of bone tissue must be understood if the appropriate renovation materials could be found 当人体发生意外时，要想找到合适的骨修复材料，必须了解骨组织本身的的材料性质，以及对骨机械性能更好的理解。
