Part I: Characterization of the stability and biocompatibility of PLGA conduits.1 Artificial nerve conduits were successfully fabricated using two different copolymer ratios of PLGA(85:15 and 50:50)(lactide:glycolide).2 Degradation of PLGA(85:15) and PLGA(50:50) conduits were examined in vitro for 12 weeks in phosphate buffered saline at 37℃, pH 7.4 and in vivo for up to 8 weeks following implantation into the rat dorsal muscle.

结果显示：①体内外降解条件下，PLGA(50：50)管吸水率、失重率及生物降解率显著高于PLGA(85：15)管；②两种材料样品体内生物降解率显著高于体外降解率；③扫描电镜观察显示，随降解时间延长，材料样品表现为特征性的虫蚀样破坏并进行性加重，以PLGA（50：50）管尤为明显。
