Effect on the micro- and ultramicro-structure of intrahepatic bile duct mediated by hypoxic preconditioning after liver graft / 中国现代普通外科进展

ABSTRACT

Objective: To investigate the change of the micro- and ultramicro-structure of in- trahepatic bile duct after liver graft and the protection of hypoxic preconditioning. Methods: The model of orthotopic autologous liver transplantation was used, thirty SD rats were randomly divided into three groups. A: orthotopic autologous liver transplantation group; B: hypoxic preconditioning before operation group; C: sham operation group. The serum bilirubin ,the micro-structure of biliary epithelial cell and the ultramicro-structure of cholangiole were determined in three groups after 48hours after operation. Results: As compared with B group: the serum bilirubin increased (P
