Summary Observations of body weight, plasma osmotic pressure, daily urine flow and daily fluid intake in a patient recovering from an œdematous state indicate that changes in both plasma osmotic pressure and body fluid volume have an influence on the volume of urine formed, and possibly on the volume of fluid drunk. The control system acts in such a way that a rise of plasma osmotic pressure produces a fall in urine flow and a rise in body fluid volume produces an increase in urine flow. A method is described which enables plasma freezing point to be determined on one millilitre of plasma.
