Abstract:
Objective To establish a new model of acute hepatic failure in canines for bioartificial liver treatment research . Methods Acute hepatic failure was induced by end to side portocaval shunt combined with common bile duct ligation and transection. The survival rate, liver function, ammonia, Fischer's ratio (BCAA/AAA) and pathological change of injury liver were investigated. Results The ammonia, ALT, AKP, total bilirubin and PT were elevated dramatically and Fischer's ratio declined significantly 14 days after the operation. The survival rate of the models decreased with time 14 days after the operation. Pathological examination of liver tissues revealed evidence of cholestasis, inflammation with accumulation of neutrophils, degeneration and necrosis of hepatocytes.Conclusions End to side portocaval shunt combined with common bile duct ligation and transection can produce a satisfactory acute hepatic failure model in canines, which could be used in the study of bioartificial liver.
