若为异物，为何没有异物反应？

These oval structures with parallel fibers within are oblique sections of normal peripheral nerves. Each and every saussage-like fiber is a myelinated nerve fiber with the bulk being myelin sheath. If you look carefully, you will see the actual axon (or axis cylinder) in its center as a small calibered red or purple fiber or dot, depending on the direction of section. These are different from suture materials.

喂，老大们，有没有搞错．这些结构可都是：

１．粗细不均．２．都有更细微的内部结构．３．束状结构外面都有纤维膜包裹．４．纤维膜外都无组织反应．

这些都不是丝线的显微镜下图象啊．仔细看看图１，你还会说是丝线吗？

不好意思了，嘿嘿．
