Abstract:
AIM: To detect the effect of sepsis on hepatic,renal functions and corresponding enzymes in intestine of mice,and to explore the role of leptin in acute inflammation.METHODS: A mice model of sepsis was made by cecum ligation and perforation,and 96-well spectrophotometry was used to detecte the levels of alanine aminotransferase(ALT),uric acid(UA) and activities of myeloperoxidase(MPO),glutathin-S-transferase(GST),xanthine oxidase(XOD),superoxide dismutase(SOD) in serum and intestinal homogenized fluids,respectively.Hematoxylin-eosin staining was used simultaneously to check the histopathologic changes of intestine.RESULTS: Compared with sham group(330.12 ?mol/L?94.15 ?mol/L),serum UA level(521.92 ?mol/L?91.86 ?mol/L) at 6 h after sepsis was significantly higher.12 h after sepsis,both serum ALT(83.55 U/L?40.44 U/L) and UA(474.03 ?mol/L?75.22 ?mol/L) were significantly higher than those in sham group(66.23 U/L?16.80 U/L and 320.95 ?mol/L?99.14 ?mol/L,respectively).12 h after leptin injection(0.1 mg/kg,ip) or indomethacin injection(2 mg/kg,ip),the serum ALT and UA levels significantly decreased(vs sepsis group,P
