The author reports the results of morphological investigations in 48 experimental shot wounds of the peripheral nerves of rabbits. In 8 animals the missile hit directly the ischiadic nerve disrupting its continuity (neurotmesis). The microscopic picture of not discupted nerves differed from one animal to another. Three types of microscopic findings were distinguished: 1) normal microscopic appearance, 2) Wallerian degeneration, 3) axonal regeneration. Normal appearance of nervous fibres was observed in all three groups of animals studied at different time intervals after injury (8-10, 18 and 56 days after injury). In the first and second groups Wallerian degeneration prevailed, while axonal regeneration was a typical finding in groups II and III. Microscopic changes in the nerves were very similar to those observed in peripheral nerves subjected to traction injury. It may be assumed that the cause of shot injury was sudden stretching of the nerve trunk in the pulsating shot channel.
作者报告了对48只家兔周围神经实验性枪伤进行形态学研究的结果。在8只动物中，子弹直接击中坐骨神经，破坏了其连续性（神经断裂）。未受损神经的微观图像在不同动物之间有所不同。区分出三种微观发现：1）正常微观外观，2）华勒氏变性，3）轴突再生。在损伤后的不同时间间隔（损伤后8 - 10天、18天和56天）对所有三组研究动物都观察到了神经纤维的正常外观。在第一组和第二组中，华勒氏变性占主导，而轴突再生是第二组和第三组的典型发现。神经的微观变化与在遭受牵引损伤的周围神经中观察到的变化非常相似。可以推测，枪击损伤的原因是神经干在脉动的射击通道中突然拉伸。
