我们做家兔眼视神经切断再生实验,开始于1981年,当年做10只兔,10只眼。1982年又做10只兔,10只眼。1983年做7只兔,12只眼。每次做家兔眼视神经切断再生实验,都能看到视神经切断后再生的视神经纤维。再生时间过程和周围神经损伤后大致相仿。再生率相当于周围神经损伤后,用外膜缝合方法的修复效果。再生方式经我们初步观察是从切口两侧缘开始;有的呈枝芽状生长,接通呈条索状,有的从两侧缘全面开始再生。不像周围神经那样,从近端开始向远端再生。
We do rabbit oculomotor cut off regeneration experiment, began in 1981, when do 10 rabbits, 10 eyes. In 1982, another 10 rabbits and 10 eyes were made. Seven rabbits in 1983, 12 eyes. Each time rabbit oculomotor nerve regeneration experiment, we can see the regenerated optic nerve fibers after optic nerve cut off. The regeneration time is similar to that of peripheral nerve injury. Regeneration rate is equivalent to the peripheral nerve injury, with the repair method of adventitia. Regeneration by our initial observation is from the incision on both sides of the edge began; some were bud-like growth, connected to a cord-like, and some from the two sides of the edge of the full start of regeneration. Unlike the peripheral nerves, regeneration begins distally from the proximal end.
