Summary
At temperatures from 15–25° C perfused rat livers take up potassium from the perfusion medium or release small amounts of the cation. Both increasing or decreasing temperature enhance the K+-release in the absence as well as in the presence of red cells. Two possible explanations of this phenomenon, hypoxia and phase-transition of the plasma membrane, are discussed.
