THE EFFECT OF GUM SHELLAC SOLUTION ON THE SURFACE TENSION OF RABBIT SERUM.
Following the intravenous injection of a gum shellac solution which alters the peripheral blood picture there is an increase in the time-drop of the diluted serum. This is believed to indicate changes in the physicochemical state of the plasma. This gum shellac solution behaves as a surface-active substance; its effect on the surface tension of serum is hindered by the du Noüy phenomenon of adsorption on serum molecules.
