Abstract |
The effects of intravenous administration of high concentration of taurocholic acid (TCA) on α-D-glucosidase nad β-D-glucuronidase activities in rat liver lysosomes were studied. Above liver lysosomal enzymes; serum lysosmal α-D-Glucosidase and total β-D-Glucosidase activities were determined from the experimental rats with choledocho-caval shunt (CCS). The activities of liver lysosomal α-D-Glucosidase and β-D-Glucosidase as well as the activities of serum lysosomal α-D-Glucosidase and total β-D-Glucosidase were significantly increased in the CCS plus TCA injection group than in control group; such as group of CCS alone group. However; these hepatic and serum enzymes activities did not change in the CCS plus tauroursodeoxycholic acid injection group. The above results suggest that TCA stimulates the biosynthesis of the lysosomal α-D-Glucosidase and β-D-Glucosidase in the liver. And that the elevated lysosomal α-D-Glucosidase and total β-D-Glucosidase activities in the serum are most likely due to increased hepatocyte membrane permeability caused by TCA mediated liver cell necrosis. |
