摘要：A new model is described which allows measurement of bile flow and sampling of bile in the intact rat with a physiologically functioning sphincter of Oddi. A number of metabolic parameters have been followed to show that animals with such an "extracorporeal bile duct" (EBD) behave as intact controls. Especially, there was no difference in the increase in body weight or hepatic fatty acid and cholesterol synthesis between EBD animals and intact controls. The amount of bile salts circulating through the biliary tract amounted to 30.5+/-1.5mumol . 100 g body wt-1 . hr-1, when diurnal variations were averaged. Animals adapted to a restricted feeding regimen showed a significant increase of bile flow and of biliary bile salt and cholesterol excretion during feeding (10AM-3 PM); these parameters reached their maximum 3 hours after onset of food intake.
