With the total number of medullated fibers in 6J rats also less than that of Ola rat ( P < 0.01), which predominated by obviously reduced big diameter fibers ( P < 0.01); 总有髓纤维数目少于Ola鼠(P<0.01),以大径纤维数目减少明显(P<0.01);有髓纤维平均直径也明显小于01a鼠(P<0.01)。
Observation with transmission electron microscope: There were regeneration medullated nerve fibers in myoblast group and extracellular matrix gel group. 透射电镜观察:成肌细胞组和细胞外基质凝胶组均见再生的有髓神经纤维。
The number of macrophage necrotic Schwann's cell was fewer than that at week 2.At week 12 regenerated medullated nerve fibers, fibrocyte and fibroblast adhered to the surface of materials; few macrophage necrotic Schwann's cells appeared. 12周时材料表面附着再生的有髓神经纤维、纤维细胞和纤维母细胞,巨噬细胞吞噬坏死变性的许旺细胞少见。
MAIN OUTCOME MEASURES: The density and size frequency distribution of sciatic nerve medullated fibers, as well as the number, the maximum diameter and the mean diameter of medullated fibers in two group of 01a rats and 6J rats. 主要观察指标:两组中01a鼠和6J鼠坐骨神经的有髓纤维密度、有髓纤维数目、有髓纤维最大直径、有髓纤维平均直径。
Analysis of regeneration nerve fiber image: After 12 week of operation, effective area of nerve fiber, the medullated nerve fibers density, quantity, diameter and neural sheath thickness of myoblast group were all better than those of the extracellular matrix gel group. 再生神经纤维图像分析:术后12周,在有髓神经纤维密度、神经纤维有效面积、有髓神经纤维数量、直径及髓鞘厚度等指标上成肌细胞组均优于细胞外基质凝胶组。
