title: Effects of lexipafant (BB-882), a platelet activating factor receptor antagonist, on liver damage due to bile duct ligation in rats.
abstract: OBJECTIVE
  Extrahepatic cholestasis is one of the main factors causing liver fibrosis. In this study, we aimed to evaluate the effects of lexipafant (BB-882), a platelet activating factor receptor antagonist, on liver damage in rats with bile duct ligation.
  
  
  METHODS
  A total of 30 male Sprague-Dawley rats weighing 160-190 g were used in this study. Group 1 (Sham-control, n = 10) rats were undergone laparotomy alone and bile duct was just dissected from the surrounding tissue. Group 2 rats (BDL/Untreated, n = 10) were subjected to bile duct ligation and no drug was applied. Group 3 rats (BDL/BB-882, n = 10) received a daily dose of BB-882 intraperitoneally for 14 days after BDL. At the end of the two-week period, biochemical and histological evaluation was processed.
  
  
  RESULTS
  The mean serum bilirubin and liver enzymes level significantly decreased, and Superoxide dismutase, catalase and glutathione peroxidase values were significantly increased in BDL/BB-882 group when compared to BDL/Untreated group. The histopathological score was significantly less in the BDL/BB-882 group compared to the BDL/Untreated rats. In the BDL/BB-882 group was observed less fibrosis and neutrophil infiltration
  
  
  CONCLUSIONS
  These results suggest that BB-882 (lexipafant) may reduce the severity of the inflammatory response to liver injury produced by bile duct ligation in rats.
