Time dependence of PCMBS inhibition of urea and water permeability at 25°C, pH 7.2, in three P
u
and two diffusional water permeability, P
d
, determinations, that are calculated from results obtained with the continuous flow tube technique and the Millipore-Swinnex filtering method. The inhibition of osmotic water permeability, Pf, refers to unpublished data.
