Inhibitory effects of NO and histamine production by A. capillaris extract (AC). A: AC inhibited NO production in LPS-stimulated (1 μg/mL, 24 hr) RAW 264.7 cells in a concentration-dependent manner (mean ± SEM (n = 3), ^##: P < 0. 01 compared with the control group, **: P < 0. 01 compared with the LPS-treated group). B: Histamine production was reduced by AC in PMA and A23187 (PA)-treated (50 nM and 1 μM, 24 hr) MC/9 cells (mean ± SEM (n = 3), ^##: P < 0. 01 compared with the control group, **: P < 0. 01 compared with the PA-treated group).
