Abstract
The aim of this study was to establish an experiment animal model for easy diagnosis and monitoring effect of treatment of cholelithiasis by cholesterol and mixed gall stone. In 12 adult beagle dogs, five dogs there were in the control group and seven dogs in the experiment group with ligated cystic duct. General clinical signs were recorded, CBC and blood chemistry were examined. Control group and experiment group were evaluated every 2 weeks for a period of 20 weeks. The results were (1) Total blirubin, cholesterol, alanine aminotransferase (ALT), aspartate aminotransferase (AST) activity were significantly higher in the experiment group with ligated cystic duct than control group during 2-8 weeks. (2) Total alkaline phosphatase (TALP) activity was significantly higher when compare with control group during 2-8 weeks. Bone alkaline phosphatase(BALP) activity was increased slightly between 2 and 8 weeks but was decreased between 10 and 20 weeks. (3) Blood urea nitrogen (BUN) was decreased between 2 and 8 weeks. After 10 weeks, this was in normal range. (4) On complate blood count (CBC), $Ca^{2+}$ and P were not changed until 20 weeks. (5) On clinical signs in experimental group, they observed a depression, yellow color of mucus membrane and conjunctiva, xanthinuria and xanthochromic. The present study showed that the experimental animal model with ligated cystic duct was a useful model to study biliary tract disease.
