Antiatopic Dermatitis Effect of Artemisia iwayomogi in Dust Mice Extract-Sensitized Nc/Nga Mice

Figure 2

A. iwayomogi (AI) extract inhibited NO and histamine production. (a) AI inhibited NO production in LPS-stimulated (1 μg/mL, 24 hr) RAW264.7 cells in a concentration-dependent manner. Each data value represents the mean ± SEM of triplicate experiments (^##𝑃<0.01 compared with the control group, ^∗𝑃<0.05 and ^∗∗𝑃<0.01 compared with the LPS-treated group). (b) Histamine production was reduced by AI in PMA- and A23187-treated (50 nM and 1 μM, 24 hr) MC/9 cells. Each data value represents the mean ± SEM of triplicate experiments (^##𝑃<0.01 compared with the control group, ^∗𝑃<0.05 compared with the PA-treated group).
