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

Figure 2

Effect of RV extract on the ear swelling and vascular permeability in DNFB-induced allergic contact dermatitis mice. (a) Representative photographs were shown. (b) The amount of extracted Evans blue dye from each ear was determined with a spectrophotometer at OD 600 nm. Each value represents the mean ± standard error (S.E.) of three independent experiments (𝑛=5 per group) (^∗𝑃<0.01 versus DNFB). (c) Thickness of H&E stained ear tissue was measured with Axiovision image analysis 4.7 software. Data are expressed as mean ± standard error (S.E.) of three independent experiments (𝑛=5 per group) (^∗𝑃<0.001 versus control; ^#𝑃<0.001 versus DNFB).
