Effect of E. africana and Baicalin on the viability of LPS-activated N9 cells. (A) N9 cells 1x105cells/ml were incubated with the indicated concentrations of E. africana and Baicalin (5 μg/ml) in the presence of LPS 1 μg/ml for 24 h. The cell viability was then determined by MTT assay as described in the Methods. (B): N9 cells incubated with DMSO for 24 h (C): N9 cells incubated with LPS (1 μg/ml) and E. africana (50 μg/ml) for 24 h. (D): N9 cells incubated with LPS (1 μg/ml) and Baicalin (5 μg/ml) for 24 h.
