AIM:To investigate the effect of meloxicam on the gut-liver axis after cirrhotic liver ***:Forty-four male Wistar rats were assigned to three groups:(1)control group(CG);(2)bile duct ligation with meloxicam treatment(BDL+M);and(3)bile duct ligation without meloxicam treatment(BDL).Secondary biliary liver cirrhosis was induced via ligatureof the bile duct in the BDL+M and BDL *** 2wk,the animals underwent a 50%*** the BDL+M group 15 min prior to the hepatectomy,one single dose of meloxicam was *** measured included:microcirculation of the liver and small bowel;portal venous flow(PVF);gastrointestinal(GI)transit;alanine aminotransferase(ALT);malondialdehyde;interleukin 6(IL-6),transforming growth factor beta 1(TGF-β1)and hypoxia-inducible factor 1 alpha(HIF-1α)levels;mRNA expression of cyclooxigenase-2(COX-2),IL-6 and TGF-β1;liver and small bowel histology;immunohistochemical evaluation of hepatocyte and enterocyte proliferation with Ki-67 and COX-2 liver ***:Proliferative activity of hepatocytes after liver resection,liver flow and PVF were significantly higher in CG vs BDL+M and CG vs BDL group(P<0.05),whereas one single dose of meloxicam ameliorated liver flow and proliferative activity of hepatocytes in BDL+M vs BDL ***-2 liver expression at 24h observation time(OT),IL-6 concentration and mRNA IL-6 expression in the liver especially at 3 h OT,were significantly higher in BDL group when compared with the BDL+M and CG groups(P<0.01,P<0.001,P<0.01,respectively).Liver and small bowel histology,according to a semi quantitative scoring system,showed better integrity in BDL+M and CG as compared to BDL *** release and HIF-1αlevels at 1 h OT were significantly higher in BDL+M compared to CG and BDL group(P<0.001 and P<0.01,respectively).Moreover,ALT release levels at 3 and 24 h OT were significantly higher in BDL group compared to CG,P<*** transit,enterocyte proliferative activity and numb
