Experimental in vitro studies have been made on the intracellular electrical activity and the extracellular wave movements of ciliary cells in rabbit trachea. The following results were obtained: 1. Surface light reflections from the mucous layer and from the ends of moving cilia showed about the same frequency and amplitude pattern as the intracellular action potential oscillations at 40 degrees C and 50 degrees C. At lower temperatures, however, there was a considerable discrepancy between them. 2. Surface light reflections from mucociliary wave movements had the same frequency in two areas 20 mum apart, but amplitude variations were out of phase. 3. Intracellular oscillations with a frequency of 18-21 per sec and a maximum amplitude of 1 mV have been recorded. Amplitude variations indicating rhythmical frequency variations have also been recorded. 4. The mean frequency of the intracellular action potential oscillations showed no remarkable differences at 20 degrees C, 30 degrees C, 40 degrees C and 50 degrees C.
已对兔气管纤毛细胞的细胞内电活动和细胞外波动进行了体外实验研究。获得了以下结果：1. 在40摄氏度和50摄氏度时，黏液层和运动纤毛末端的表面光反射显示出与细胞内动作电位振荡大致相同的频率和振幅模式。然而，在较低温度下，它们之间存在相当大的差异。2. 相距20微米的两个区域中，黏液纤毛波动的表面光反射频率相同，但振幅变化不同步。3. 已记录到频率为每秒18 - 21次且最大振幅为1毫伏的细胞内振荡。还记录到了表明节律性频率变化的振幅变化。4. 在20摄氏度、30摄氏度、40摄氏度和50摄氏度时，细胞内动作电位振荡的平均频率没有显著差异。
