[Solubilization of cholesterol by sodium salts of bile and fatty acids].

Solubilization of cholesterol by sodium salts of cholic, glycocholic, deoxycholic, lithocholic and oleic acids was studied. Dynamics of the solubilization process is described and a comparative characteristic of solubilizing ability of the substances under investigation is given. Cholesterole solubilization is studied as dependent on the concentration of the given substances.

[Effect of bile acids and other surface-active substances on antidiuretic hormone regulation of epithelial membrane permeability].

Surfactants in low concentrations (1.10(-5) and 1.10(-4) g/ml) altered the action of the antidiuretic hormone on the permeability of the wall of frog urinary bladder.

[The influence of several surface-active substances on neuromuscular transmission of excitation].

Microelectrode method was applied to the study of the influence of sodium bile salts (BS), saponin and between-80 on the end-plate potentials (EPP) of m. sartorius of Rana ridibunda. Bile salts in a concentration of 10(-5) g/ml did not change these potentials significantly.
