Effect of silver nanoparticles (NPs) on bronchial inflammation in ovalbumin (OVA)-sensitized and OVA-challenged mice. Sampling was performed 72 hours after the final challenge in saline-inhaled mice administered saline (SAL), OVA-inhaled mice administered saline (OVA), saline-inhaled mice administered 40 mg/kg of silver NPs (Ag 40), and OVA-inhaled mice administered 40 mg/kg of silver NPs (OVA + Ag 40). A−D) Representative H&E-stained sections of the lungs. Bars indicate scale of 50 μm. E) Total lung inflammation scores. F) The numbers of total and differential cellular components of bronchoalveolar lavage (BAL) fluids. Bars indicate the mean ± SEM for eight mice per group in four to six independent experiments. *P < 0.05 versus SAL; #P < 0.05 versus OVA.
