Permeability of trout erythrocytes to nonelectrolytes.
Using a densimeter technique, a kinetic analysis was made, employing both entrance and exit studies, of the permeability of erythrocytes of brook trout (Salvelinus fontinalis), rainbow trout (Salmo gairdneri), German brown trout (Salmo trutta) and cutthroat trout (Salmo clarki) to glycerol, ethylene glycol, thiourea and urea. All of the data indicate that these four nonelectrolytes cross the membrane of the erythrocytes of these four species of fishes by simple diffusion only.
