[Objectives] Taking mice with acute liver injury induced by CCl_4 as the model,the effect of arabinose + mannose( w/w = 1∶ 1) on mice with acute liver injury induced by CCl_4 was studied. [Methods]60 experimental mice were selected and then randomly divided into normal control,model group and positive group( bifendate 120 mg/kg),high-dose arabinose + mannose group( 800 mg/kg),middle-dose arabinose + mannose group( 400 mg/kg) and low-dose arabinose + mannose group( 200 mg/kg),each group had 10 mice,which were fed adaptively for 1 week. Except normal control group and model group,each treatment group was given medicine by gavage once a day and lasted for7 days according to the dosage of 20 ml/kg. After the last drug,except normal control group,the mice of other groups were injected 10 ml/kg0. 12% CC14 peanut oil through enterocoelia,thereby establishing acute liver injury model. The mice were fasted but not water for 24 h,after that,blood was sampled from mice eyes,then dissected rapidly. The activities of ALT and AST in the serum were determined,the expression levels of TNF-α,IL-1β and IL-6 from the hepatic tissues were detected by enzyme-linked immunosorbent assay( ELISA); then after HE dye,the changes of liver histopathology were observed. [Results]Compared with CCl_4 model,the activities of ALT and AST from the serum of mice from high-dose and middle dose groups decreased significantly( P < 0. 01); the contents of TNF-α,IL-1β and IL-6 from the hepatic tissues of mice decreased significantly( P < 0. 01); the pathological section showed that the liver injury of mice from the combined drug groups showed alleviating trend to varying degrees,in which the liver injury of mice from the high-dose group was the best. [Conclusions] Arabinose + mannose has an obvious protective effect on mice with acute liver injury induced by CCl_4,and its mechanism may relate to anti-inflammatory.
