[Changes in bile composition in rabbits infected with Clonorchis sinensis]
1Department of Infectious Diseases, Sun Yat-Sen University of Medical Sciences.
Summary
Clonorchis sinensis infection significantly increases bacterial beta-glucuronidase activity and glycoprotein in rabbit bile. This may explain the higher incidence of gallstones in clonorchiasis.
Area of Science:
- Parasitology
- Biochemistry
- Hepatology
Context:
- Clonorchiasis, a parasitic infection caused by Clonorchis sinensis, affects the biliary system.
- Gallstones (cholelithiasis) are a common complication of chronic parasitic infections.
Purpose:
- To investigate the biochemical changes in hepatic bile of rabbits infected with Clonorchis sinensis.
- To determine the relationship between Clonorchis sinensis infection and the risk of cholelithiasis.
Summary:
- Rabbit bile infected with Clonorchis sinensis showed significantly elevated bacterial beta-glucuronidase activity compared to controls.
- No significant changes were observed in bilirubin, cholesterol, phospholipid, or bile acid concentrations.
- Increased glycoprotein secretion into the biliary duct was noted in infected rabbits.
Impact:
- The study suggests that increased bacterial beta-glucuronidase activity and glycoprotein levels in bile contribute to pigment gallstone formation in clonorchiasis.
- Findings provide a biochemical basis for the observed association between Clonorchis sinensis infection and cholelithiasis.
