摘要
报道了聚 d ,l 乳酸在大鼠体内的降解 ,以及用聚d ,l 乳酸制备的神经诱导管对大鼠坐骨神经 2 0mm断缺修复的研究。通过肉眼观察、组织学检查、电镜观察、以及电生理测定等方法和手段 ,对神经诱导再生过程进行了跟踪 ,揭示了随着神经的再生聚d ,l 乳酸管形态的变化 ,且对神经修复的效果进行了评价。研究表明 :用聚d ,l 乳酸管可成功地诱导 2 0mm断缺神经得到再生修复。
WT5BZ]Degradation of poly d,l lactide in vivo and 20mm nerve gap recovered by poly d,l lactide guide were reported. The effects of nerve recovery were examined by the techniques of gross observation, tissue testing, SEM determination, and electronic physiological examination. In result that the poly d,l lactide can be effectively used as nerve guide and 20mm nerve gap successfully recovered by poly d,l lactide guide were demonstrated.
