[Carbohydrate absorption in the rat small intestine following ligation of the bile duct].
Active transport of free glucose, and glucose released from maltose and starch hydrolysis (F-, M-, and S-glucose, respectively) was investigated in vitro in the rat small intestine 7 and 14-17 days after the ligation of the common bile duct or after the laparotomy (control). The relative role of the ileum (its proximal portion in particular) in active transport of F- and M-glucose was enhanced following ligation of the common bile duct as compared with the control (laparotomy). The active transport of S-glucose was relatively low in the control and actually absent after the ligation of the common bile duct. The findings seem to reflect adaptive-compensatory responses of intestinal mucous membrane to insufficiency of the lumen digestion of carbohydrates due to exclusion of bile from the process.
