摘要
为进一步研究静脉套接法修复面神经段缺损的效果，用辣根过氧化物酶（ｈｏｒｓｅｒａｄｉｓｈｐｅｒ－ｏｘｉｄａｓｅ，ＨＲＰ）标记法，观察大鼠面神经干经静脉套接修复后，面神经核内神经元的变化，并与神经原位移植及正常对照组比较。结果表明：①自体静脉能象自体神经一样修复面神经小段缺损；②两种修复法均存在轴突误向再生的问题；③经两种方法修复后，同侧靶器官接受对侧神经元支配的可能性极小；④静脉修复面神经后，周围与中枢的关系恢复可能更接近于正常。
For further study of the effects of the repairment of facial nerve with vein tubulation, we used horseradish peroxidase (HRP) retrograde mark method to observe the changes of the labeled cells in facial neucleus after the tubulation of rat facial nerve. And, we compared the changes with nerve graft in situ and the normal group. The results showed: ① The vein tubulatiton can repair the short defect of facial nerve as well as the nerve graft does. ② Irregular outgrowth of axon sprouts could be found in both methods. ③ There was few chance for homolateral target organ to be reinnervated by contralateral motoneurons in both methods. ④ Using the vein tubulation method, a more natural relationship between the peripheral target organ and central nucleus may be easily achieved.
