Expression of calcitonin gene - related peptid - immanoreactivity positive fibers in dorsal root ganglion and nerve trunk after end - to - side neurorrhaphy
Abstract：Objective To study the regeneration of calcitonin gene - related peptid(CGRP) immunoreaetivity positive fibers after endto - side neurorrhaphy. Mefthods The model of the rabbit greater auricular nerve end - to - side anastomosis was used in the paper. The neuros and fibers were labeled with immunohistochemisty. Results One week later, the expression of CGRP immunoreactivity was weakly positive in donor nerve. With times went the expression of CGRP immunoreactivity positive fibers rose rapidly. In the fourth week the receptor nerve acquired reinnervation. CGRP of receptor never positive cells remained weakly positine. Conclusion CGRP positive fibers were able to arcoss the nerve gap to enter receptor nerve, regeneration of fibers was step by step.
