ABSTRACT
Objective To observe the protective effects of FTY720 on the Con A-induced mouse hepatic fibrosis injury,and to find the possible mechanisms of protective effects.Methods The pathologic models of hepatic fibrosis injury in the mice caused by Con A were set up.Forty mice were randomly divided into control group, model group,high dose of FTY720 (4 mg·kg-1 )group and low dose of FTY720 (1 mg·kg-1 )dose group (n=10).The serum alanine aminotransferase (ALT)and asparate aminotransferase (AST)activities,hepatic index and pathological changes of hepatic tissue were detected .Results Compared with model group,the serum ALT and AST activities in low and high doses of FTY720 groups were decreased significantly (P < 0.05 or P < 0.01).The optical microscope results showed that there were inflammatory cells and hepatocellular necrosis in model group. The masson staining results showed that there were surrounding fiber bundle and hepatic lobule fusion in model group;compared with model group,the damage degree in low and high doses of FTY720 groups was reduced.The protective effects of FTY720 on hepatic injury showed linear relation to the drug dose.Conclusion FTY720 could decrease the levels of ALT/AST,thus FTY720 alleviate hepatic damage degree and delay the process of hepatic fibrosis.The protective effects of FTY720 on hepatic injury in experimental hepatic fibrosis mice may be related to the mechanisms mentioned above.
