RESUMEN
Aim To determine potential biomarkers contributed to occurrence, development and recovery of ethanol-induced liver injury in rat and elucidate hepatoprotective effect of Yin Chen Hao Tang based on metabonomic investigation. Methods A UPLC-Q-TOF/MS based metabonomic method was developed for investigating trajectory change and inter-relationship of urinary metabolome of rats with different treatments. Results Four potential biomarkers were determined which contributed to occurrence, development and recovery of ethanol-induced liver injury in rat, and Yin Chen Hao Tang could significantly recover trajectory change in disorder. Conclusion The developed method was successfully applied to investigate ethanol-induced liver injury in rat, and also hepatoprotective effect of Yin Chen Hao Tang was elucidated.
