The rate of transfer of labeled molecules across a sheet of quiescent cat right ventricle separating two chambers containing chemically identical solutions was followed at 23 degrees C. For the diffusion of sucrose, SO(4), and Na the experimental points fit the entire time course of the plot of the diffusion equation for a plane sheet. The tortuosity factor of the extracellular diffusion channel, lambda was 1.44 +/- 0.05 (mean +/- SEM) for sucrose and similar for SO(4) and Na. The fractional… CONTINUE READING
