title: [Calculi formation and biliary hydrodynamics].
abstract: In this study, 167 white rabbits were divided into 5 groups to observe the effects of biliary stricture and infection on the formation of bile duct stones and the pathophysiological changes of the biliary tract. It was found that there was a gradient of static hydraulic pressure along biliary tract and the pressure was directly proportional to hepatic blood flow. In the rabbits with bile duct stone formation, the activity of SDH, ATP ase and glycogen (PAS) in the mucosa of biliary tract was low and that of LDH was high. In the biliary tract wall damaged by infection and choledocholithiasis, a frame work consisting of polysaccharide protein, mucin, and mucoid polymer was observed and the authors considered it as one of causing factors in the formation of the stones.
