ABSTRACT

Objective:To explore the protective effect of ellagic acid on the acute liver injury induced by carbon tetrachloride (CCl4) of the mice,and to explore its possible mechanism.Methods:A total of 50 mice were randomly divided into normal control group,model group,low,medium and high doses of ellagic acid groups (n=10).The mice in normal control group and model group were treated with 1% sodium carboxymethyl cellulose solvent by intragastic administration,and the mice in ellagic acid groups were treated with 160,320,and 480 mg·kg-1 ellagic acid by intragastic administration,respectively.After 14 d,the mice in model group and different doses of ellagic acid groups were intraperitoneally injected with 10 mL·kg-1 0.1% CCl4,while the mice in normal control group were intraperitoneally injected with 10 mL·kg-1plant oil.16 h later,all the mice were sacrificed and the body weights and the liver indexes of the mice were detected;the serum levels of alanine transaminase(ALT),aspartate transaminase(AST) were detected;the activities of superoxide dismutase(SOD) and levels of GSH-Px,malonalde hyde(MDA) and catalase(CAT) in liver tissue of the mice were detected.Results:There were no significant differences of the body weights of the mice between each group before and after treatment(P>0.05).Compared with normal control group,the liver indexes and the levels of serum ALT and AST of the mice in model group and different doses of ellagic acid groups were significantly increased (P<0.05).Compared with model group,the liver indexes of the mice in different doses of ellagic acid groups were decreased(P<0.05);the serum levels of ALT and AST of the mice in high dose of ellagic acid group were significantly decreased (P<0.05),while the CAT level in liver homogenate was significantly increased (P<0.05);the levels of GSH-Px in liver homogenate of the mice in medium and high doses of ellagic acid groups were significantly increased (P<0.05);the activities of SOD in liver homogenate of the mice in different doses of ellagic acid groups were significantly increased (P<0.05),and the MDA levels were significantly decreased (P<0.05).Conclusion:The ellagic acid has the protective effect on acute chemical liver injury in the mice induced by CCl4 and the most effective dose is 480 mg·kg-1;its mechanism may be related to the anti-oxidation.
