The author attempted to clarify the histological changes after exposure to ethyl alcohol of superior cervical ganglion (SCG) cells in chronological order. Adult rat SCGs in situ were immersed in ethyl alcohol for various durations and were observed under light microscopy after fixation and histological processes. In almost all cases, the visages of the cells were in devastated state, although the grade of inflammatory reaction depends on the duration of exposure to the ethyl alcohol. In cases of short-lasting immersion, only the cells located near the capsule showed the so-called coagulation necrosis and those at the center of SCG were not so severely affected. Inflammatory reactions characterized by cellular invasion was also determined by duration of ethyl alcohol exposure. Number of normal neurons decreased until 60 days after immersion. From this study, it was revealed that complete ethyl alcohol blocking of the SCG depends on the duration of immersion time and the days after this procedure.
作者试图按时间顺序阐明颈上神经节（SCG）细胞暴露于乙醇后的组织学变化。将成年大鼠原位SCG浸入乙醇中不同时长，经固定和组织学处理后在光学显微镜下观察。几乎在所有情况下，细胞外观均呈破坏状态，尽管炎症反应的程度取决于乙醇暴露时长。在短期浸泡的情况下，仅位于被膜附近的细胞出现所谓的凝固性坏死，而SCG中心的细胞受影响不那么严重。以细胞浸润为特征的炎症反应也由乙醇暴露时长决定。正常神经元数量在浸泡后60天内减少。从这项研究可知，SCG的完全乙醇阻滞取决于浸泡时间和该操作后的天数。
