Extract of Rhus verniciflua Bark Suppresses 2,4-Dinitrofluorobenzene-Induced Allergic Contact Dermatitis

Figure 5

Effect of RV extract on NO production and iNOS protein expression in lipopolysaccharide- (LPS-) stimulated RAW264.7 macrophages. (a) Cell viability of RV extract was determined by the EZ-CyTox kit. (b) Nitrite production in medium was determined using Griess reagent assay. (c) The protein expression of iNOS was analyzed by Western blot analysis. Data are represented as mean ± standard error (S.E.) of three independent experiments. One-way ANOVA was used for comparisons of multiple group means followed by Dunnett’s 𝑡-test (^#𝑃<0.001 versus control; ^∗𝑃<0.01, ^∗∗𝑃<0.05, ^∗∗∗𝑃<0.001 versus LPS-stimulated control).
