Lung tissue in sensitized mice exposed to ovalbumin and DK-1014. (a) Histological examination of lung tissue performed using H&E staining for airway inflammation (arrows indicate inflammatory cells). (b) PAS staining for mucus secretion (arrows indicate mucus cells). Original magnification was ×100. NC = normal control mice treated with PBS only; OVA = ovalbumin sensitized/challenged mice; Mon = ovalbumin sensitized/challenged mice treated with montelukast (30 mg/kg); DK-1014 = ovalbumin sensitized/challenged mice treated with DK-1014 (30 mg/kg). ##p < 0.005 compared to the normal control; **p < 0.005 compared to OVA mice.
