Results The degeneration changes of free nerve endings and sensory corpuscles were observed after 2 weeks. 结果失神经后2周,游离神经末梢和感觉小体开始溃变;
Conclusion The implanted nerve might recover the functional and structural integrity of sensory fibers and innervate the degenerative corpuscles. 结论植入的神经恢复了感觉神经结构和功能的完整性,可以使感觉小体获得神经再支配。
Results: After nerve was cut off, the axons of Merkel's cell-neurite complexes degenerated till the basic structure of the corpuscles disappeared completely. 结果:Merkel氏细胞轴突复合体随失神经时间延长逐步减少,直至完全消失;
METHODS Nerve was implanted into the denervated finger skin of monkey, the samples were taken from monkey finger palm after nerve implantation, and marked by immunohistochemical staining, the regeneration free nerve endings and sensory corpuscles were observed. 方法猴手指皮肤造成失神经支配并植入神经,于术后12mo取指腹标本利用免疫组织化学染色技术观察游离末梢和感觉小体再生情况。
Objective To study degeneration of free nerve endings and sensory corpuscles after nerve injuries. 目的研究神经损伤后,感觉神经末梢的溃变过程。
