The effects of unilateral and bilateral intrathoracic vagotomy on the neuronal structure of the dorsal motor nucleus of the vagus were studied in rabbits. Degeneration affected mainly the small neurones which disintegrated and vanished from dorsal motor nucleus relative to the survival time after operation. A substantial proportion of large neurones was lost or degenerated, but some were preserved unchanged. In unilaterally vagotomized rabbits the dorsal motor nucleus of the intact side showed scattered neurones with axonal reaction which stands up for peripheral crossing of the vagi. The degree of retrograde degeneration was largely determined by the survival time. The nucleus ambiguus was bilaterally preserved unchanged.
在兔身上研究了单侧和双侧胸段迷走神经切断术对迷走神经背运动核神经元结构的影响。变性主要影响小神经元，这些小神经元相对于术后存活时间从背运动核解体并消失。相当一部分大神经元丢失或变性，但有些保持不变。在单侧迷走神经切断的兔中，完整侧的背运动核显示有散在的具有轴突反应的神经元，这支持迷走神经的外周交叉。逆行变性的程度在很大程度上取决于存活时间。疑核双侧保持不变。
