Effect of Alpinia katsumadai Hayata on House Dust Mite-Induced Atopic Dermatitis in NC/Nga Mice

Figure 2

Effect of AKH extract on LPS-stimulated NO and PGE₂ production in RAW 264.7 cells. The production of NO (a) and PGE₂ (b) was measured in culture medium of cells treated with AKH extract (2–50 μg/mL) and then costimulated with LPS (1 μg/mL) for 18 h. L-NMMA (10 and 100 μM) and indomethacin (10 and 100 μg/mL) were used as positive control drugs. Each bar represents the mean of three independent experiments. ^##𝑃<0.01 versus vehicle control group; ^*,**𝑃<0.05 and 𝑃<0.01 versus LPS-treated cells, respectively.
