镁基合金应用于生物医用材料的研究进展 贾东煜1,沈阳1,葛淑萍1,王贵学1,张勤1 (1.重庆大学生物工程学院生物流变科学与技术教育部重点实验室,重庆,400044) 摘要:镁基合金具有较高的强韧性和加工性能以及较好的生物相容性,可应用于骨组织工程,整形外科以及血管支架中.而镁基合金在人体体液环境下的腐蚀性又反过来影响其使用寿命.采用适宜的改性方法不仅可以提高镁基合金的耐腐蚀性能,降低其生物降解速率,而且可以进一步提高其力学性能和表面生物活性.综述了镁基合金的力学相容性,生物相容性,可降解性以及针对以上性能的各种改性方法,并评述了国内外对镁基合金医用生物材料的应用研究概况. 关键词:镁基合金; 力学相容性; 生物相容性; 可降解性; magnesium alloys; biomechanical compatibility; biocompatibility......
纯镁在动物体内骨诱导性能的研究 高家诚1,王勇1,乔丽英1,辛仁龙1 (1.重庆大学,重庆,400045) 摘要:将改性前后的4N-Mg以及TC4合金对照样植入白兔股骨,术后2, 6, 12 w时任取1只处死,进行X线片检查,血镁浓度测试,并对标本进行SEM观察,EDS分析,以及组织切片光镜观察.结果表明,骨内植入试验中,动物血镁浓度均在正常值范围之内;镁基植入材料显示出较好的骨结合性和骨诱导性,新生骨组织矿化明显,新生骨层上有排列整齐的破骨细胞;改性镁基材料的腐蚀降解速率明显减小.初步表明镁基材料有较好的骨诱导性能,改性对镁基材料腐蚀降解有调控作用. 关键词:镁; 表面改性; 生物相容性; 骨诱导性; magnesium; surface modification; biocompatibility; bone inducement; [全文内容正在添加中] ......
: Mg-based scaffold; biocompatibility; antibacterial activities; bioactivity; corrosion behavior 1 Introduction Throughout the history of biomedical engineering, finding an alternative material for repairing bone defects has been a critical issue [1-3]. Magnesium (Mg) has drawn much attention as a bone substitute material due to its biodegradability, biocompatibility, and appropriate mechanical......
