Effect of prolonged ovalbumin (OVA) challenge on lung tissue pathology. Representative photomicrographs of (a) haematoxylin/eosin (H&E)- (arrows depict eosinophils), (b) periodic acid-Schiff (PAS)- and (c) Martius scarlet blue (MSB)-stained lung sections from alum control mice, OVA challenged mice at day 24 (acute phase) and day 55 (chronic phase), and mice that were no longer exposed to OVA from day 55 and killed at day 80 are shown (original magnification × 40). Data is representative of n = 9–17/group/time point.
