我们采用体视学分析的整体量化的舌下神经（XII）运动神经元在成年大鼠，接受不同程度的切除的XII神经。在单侧XII神经主干处制作不同长度的神经间隙（0.0- 13.3mm），并在神经切除后12周计数损伤侧和未损伤侧的XII神经元总数。不同长度的神经切除后，体视学估计的XII神经元总数减少，存活率范围为34.4%至87.1%。在切除神经的长度增加和XII神经元存活减少之间观察到统计学上显著的负相关。结论：神经切除后，XII神经元的总数减少，XII神经元的存活率与切除神经戳之间的距离有关。
We employed stereological analyses for whole quantification of hypoglossal (XII) motoneurons in adult rats that received varying degrees of resection of the XII nerve. Various lengths of nerve gaps (0.0–13.3 mm) were made at the main trunk of the unilateral XII nerve, and the total number of XII neurons on the injured and uninjured sides was counted 12 weeks after nerve resection. The stereologically estimated total number of XII neurons decreased after various lengths of nerve resection, and survival rates ranged from 34.4% to 87.1%. Statistically significant negative correlations were observed between increasing length of the resected nerve and decreasing XII neuron survival. It was concluded that the total number of XII neurons decreased after nerve resection and that survival rates of XII neurons were related to distances between resected nerve stamps.
