ABSTRACT
Aim Toexamineliverdamagebyrifampi-cin and hepatic gene expression related to bile acid me-tabolisminmice.Methods Adultmalemicewere given rifampicin(180 mg·kg-1 ,po)daily for 30 days and(90 mg·kg-1 ,po)daily for 90 days,blood bio-chemistry,histopathology,and gene expression were examined.Results Rifampicinincreasedanimalliver index and serum enzyme activities. Histopathology showed steatosis and spotted feathery-like degenera-tion.Rifampicin increased the expression of CYP7A1 after 30 and 90 days of administration,along with in-creased FXR and SHP.Rifampicin reduced the expres-sion of BSEP after 30 days of high dose administration. Conclusion Repeatedadministrationofrifampicin may cause liver injury and intrahepatic cholestasis in mice,and these effects are associated with the altera-tion of gene expression related to bile acid metabolism.
