Effects of ibuprofen-acyl-glucuronide on the cell viability.

MTT assay was conducted to investigate the effects of ibuprofen-acyl-glucuronide on the cell viability of HaCaT cells. Each column is the mean ± S.D. of three independent determinations. *, P < 0.05; **, P < 0.01, compared with the cell viability of the control cells.
