A systematic morphometric examination of the vagus nerves at different levels obtained at autopsy in 4 control subjects and 6 alcoholic patients. Morphometric studies on myelinated fibres were performed on the nerve at the mid-cervical, lung hilum and diaphragmatic levels. In the patients with alcoholic neuropathy there was a significant reduction in density of myelinated fibers in the distal part of the vagus nerves when compared with controls. The more severe distal degeneration in the nerves and the pathological changes of axonal degeneration distally are consistent with the dying back neuropathy. The relation between the secondary segmental demyelination and degeneration of the involved nerves were discussed.
对4名对照受试者和6名酒精性患者尸检时获取的不同水平迷走神经进行系统的形态计量学检查。对颈中部、肺门和膈肌水平的神经进行了有髓纤维的形态计量学研究。与对照组相比，酒精性神经病变患者迷走神经远端的有髓纤维密度显著降低。神经更严重的远端变性以及远端轴突变性的病理变化与逆行性神经病变一致。讨论了受累神经的继发性节段性脱髓鞘与变性之间的关系。
