[Findings in intrahepatic bile ducts after ligation of the choledochus in an experiment].

The elevation of intraductal bile pressure in hepatic tissue of rats manifested itself a few hours later the ligation of common bile duct by focal dilatation of bile canaliculi which was followed by proceeding concentration of pericanalicular ectoplasma of hepatocytes and partial renewal of contractility of canalicular system. Later, proliferation of interlobular bile ducts together with a relatively rapid loss of pericanalicular density followed. New - built bile ducts scarcely infiltrated by polynuclear leucocytes proceeded from margins of portal tracts in between trabecules of hepatocytes in the periphery of lobules.
