Effect of ethyl acetate (EA) fraction of ethanolic extract from Scutellariae radix on viability of monocytic THP-1 cells, and pro-inflammatory cytokine productions by P. acnes-stimulated THP-1 cells. Cell viability (A) was determined by MTT assay in cells incubated with vehicle control alone, or the indicated concentrations of EA fraction for 24 h. IL-1β (B) and IL-8 (C) were determined in cells co-incubated with P. acnes (M.O.I. = 75) and the indicated concentrations of samples for 24 h. DMSO (0.1%) was a vehicle control, luteolin was a reference control. A control experiment without P. acnes treatment was conducted in parallel. Each column shows the mean ± SD. Values with the same letter are not significantly different as determined by Duncan’s multiple range tests.
