[Regulation of isolated rat hepatocyte volume in hypoosmotic media].
Isolated hepatocytes behave like osmometers immediately after an incubation in hypo-osmotic media. During long-term incubation periods they recover their normal volume either in the absence or in the presence of ouabain. The volume regulation is parlty due to a decrease in intracellular potassium and amino acid contents.
