  • Effects of Activities of Na+K+ATPase in Plasma Membranes of Hepatocytes in the Formation of Calcium Bilirubinate Gallstone

    Objective To investigate the effects of activities of Na+K+ATPase in plasma membranes of hepatocytes on the formation of calcium bilirubinate gallstone. MethodsThe research were studied in Xiao’s rabbit models.One hundred and three rabbits were randomly divided into the control group (Con,n=28),simple biliary obstruction group (BO,n=36),biliary obstruction and infection group (BOI,n=39).The activities of Na+K+ATPase,contents of intracellular calcium and bile acids in bile were measured in 3rd,7th,14th and 20th day. ResultsThe activities of Na+K+ATPase,contents of bile acids in bile decreased gradually and the contents of intracelluar calcium of hepatocytes increased continously in all phases of experimental groups compared with control group (P<0.01).There was more significant changes in BOI group than in BO group (P<0.05). Conclusion The progressive decrease of activities of Na+K+ATPase has a close relationship with the overloaded intracellular calcium and the continous decrease of bile acids contents in bile in formation of calcium bilirubinate gallstone.Infection can promote above mentioned changes and more stone formation.
