摘要：
1. Kinetics of potassium transport across trout gills was studied, using an isolated-head preparation. 2. Potassium exchanges were shown to take place across secondary lamellae only. 3. Influx of potassium was saturable and fitted satisfactorily the Lineweaver-Burk linear plot. 4. Results suggest that these exchanges occur through potassium channel. 5. Kinetics of potassium exchanges is discussed in relation to the maintenance of the osmoregulation in fish.
