[Concentration of water and electrolytes in rat liver during absorption of salt solutions]

Administration of water and 0.9% NaCl; 1.25% KCl; 0.75% MgCl2 solutions (5 ml/100 g body weight) into the rat stomach revealed that large amount of water was not detained in the liver but just passed through it. The electrolytes contents did not change significantly in the liver. Administration of KCl and MgCl2 solutions increased concentration of respective cations in the blood. The data obtained suggest that water and salts absorbed in the small intestine pass through the liver into the general blood flow and are detained in different tissues.
