Abstract

Na125I and 131I-labeled albumin was infused in dogs into the common bile duct at pressures of 20 to 25 and 40 mmHg. At 40 mmHg, the amounts of the iodide ion and labeled albumin in circulating plasma were, after correction for the secondary loss from the circulation, nearly identical. At 20-25 mmHg more iodid than labeled albumin was found in the circulation. In thoracic duct lymph the same fraction of the infused amount of albumin was recovered at both pressures. Lymphatic concentrations of albumin were in both types of experiments substantially higher than plasma concentrations. It is concluded, that at increased pressure fluid leaks first from the small biliary ducts into the Mall's spaces. In consequence of water absorption and the diffusion of ions and small molecules into the blood capillaries the concentrations of protein or protein bound molecules in this part of the hepatic interstitial fluid increases. This is reflected in their high concentration in the lymph. If bile pressure rises further, fluid leaks also into the Disse's spaces. This leads to a bulk flow of solvent and solutes into the sinusoids and to the near disappearance of the differences in the venous transport of ions and colloids.
