Bronchoalveolar lavage differential cell counts and macrophage expression of arginase 1. A) Differential cell counts from BAL samples in the sub-acute model OVA/PBS (□) and OVA/OVA (■) mice exposed to FA or CAP+O3 (*P < 0.05). (B) Images of arginase 1 immunostained slides of BAL samples and quantification of the percentage of positive macrophages (400× magnification; bar = 100 μm; brown colour indicates positivity; representative images of n = 5-6/group; *P < 0.05, **P < 0.01).
