Fig. 3. Concentration of cytokines in nasal lavage fluid. (A) The concentration of IL-4 in the nasal lavage fluid was significantly elevated in group 2 (G2) compared to group 1 (G1). The IL-4 concentrations were also significantly lower in group 3 (G3) and group 4 (G4) than in G2. (B) The IL-5 concentration in G2 was significantly higher than that in G1, G3 or G4. (C,D) There were no significant differences in IL-10 or IFN-γ concentrations between G2 and G3 (*p<0.01, ^†p<0.05). G1, normal saline; G2, ovalbumin (OVA)+saline; G3, OVA+Korean red ginseng; and G4, OVA+dexamethasone (graph: average±standard deviation).
