Die Verteilung der Na- und Cl-Ionen zwischen Blutserum einerseits, Pleurapunktat, Ascites und Liquor cerebrospinalis andererseits

Summary

We determined the sodium, chloride, and protein content of sera on the one hand, and the same constituents in pleural, ascitic and cerebrospinal fluid on the other. We found the proportions of sodium and chlorine of serum and corresponding fluid to be identical with the proportions calculated according tovan Slyke's formula on the basis of the Donnan equilibrium. Consequently one cannot draw any diagnostic conclusions from the sodium or chlorine content of these fluids, as they depend solely on the sodium or chlorine content of the serum and the protein content of the serum and fluid.
