为了有助于分析人类耳蜗电图的结果，使用24只白化病豚鼠检查了短暂缺氧后耳蜗电位（AP、CM和SP）的可逆性。缺氧时间5~120 min，恢复血供后1 h测定AP、CM和SP。短暂缺氧后耳蜗损害的最轻微形式是AP的L部分消失，最严重的是这些电位完全消失。损伤程度与缺氧时间长短密切相关。AP的可逆性差于CM和SP。这些结果进行了分析和讨论，根据文献的临床和基础研究。
To contribute to the analysis of the electrocochleographical findings in humans, the reversibility of the cochlear potentials (the AP, CM, and SP) after transient anoxia was examined using 24 albino guinea pigs. The durations of anoxia ranged from 5 to 120 min, and the AP, CM and SP were examined one hour after restoration of the blood supply. The mildest form of cochlear damage after transient anoxia was the disappearance of the L-part of the AP and the severest was the complete abolition of these potentials. The severity of the damage closely correlated with the duration of anoxia. The AP was poorer in reversibility than the CM and the SP. These results were analysed and discussed in the light of literature on clinical and basic studies.
