  ABSTRACT: The incidence of gallstone is higher in patients with diabetes mellitus than in general popula- tion. It is generally attributed to hypomotility and lowered emptying function of the gallblad- der. In this study, we investigate if chronic hy- perglycemia is correlated with reduced contrac- tile function of the bile ducts in rat. Hypergly- cemic rats were induced by streptozotocin-nic-otinamide treatment. Hyperglycemic rats were sacrificed eight months after induction and bile ducts were removed for the subsequent studies. The bile duct contractility of the normal rats is consistently higher than that of the hypergly- cemic rats. The contractities were measured to be 5.5 ± 0.2 mg vs. 4.2 ± 0.1 mg without CCK stimulation, and 5.5 ± 0.3 mg vs. 7.9 ± 0.4 mg with CCK stimulation, respectively for hypergly-cemic and normal rats. There was no significant difference in plasma CCK concentration in hy- perglycemic rats and normal rats. The expres- sion of CCK-A receptor protein in the bile duct tissue was decreased in hyperglycemic rats compared with that of the normal rats, and it may, at least in part, responsible for a reduced contractility. A reduced bile duct motility may cause bile retention, and may be one of the factors predispose to gallstone formation in type 2 diabetes patients, which is characterized with chronic hyperglycemia.
