Fig. 2. Detection of inflammatory mediators in the nasal secretion of the NPT-positive and NPT-negative groups. The levels of (A) ECP, (B) tryptase, (C) IL-8, and (D) VEGF were measured. The horizontal bars indicate positive cutoff values (mean+3 SD). All values were adjusted for the protein ratio. NPT, nasal provocation test; ECP, eosinophil cationic protein; IL, interleukin; VEGF, vascular endothelial growth factor.
