Figure 3.

Effect of thymic stromal lymphopoietin (TSLP) and chemoattractant receptor homologous molecule expressed on Th2 (CRTH2) antagonist on lung histopathology and goblet cell hyperplasia. Representative photomicrographs of (A) H&E and (B) periodic acid Schiff (PAS) stained lung sections (×200) from mice of the treatment groups are shown. (C) Quantification of the PAS-stained area by point scoring. Values are expressed as mean ± SEM (n = 5 to 8/group). CON, control; OVA, ovalbumin. ^a p < 0.05 and ^b p < 0.001 compared with the CON group, ^c p < 0.01 compared with the OVA group.
