Effects of GBBAEs on secretions of PGE₂ (a), IL-1β (b), IL-6 (c), and INF-γ (d) in LPS-stimulated murine RAW 264.7 cells

Cells were pretreated with LPS (1 μg/ml) before stimulated with 400, 800, and 1200 μg/ml of GBBAEs in the presence for 24 h, respectively. As a control, cells were incubated with vehicle alone. The reported values are the mean±SD (n=3). Different letters indicate significant differences (P<0.05)
