BALB/c mice (6–7 wk old) were anesthetized by isoflurane inhalation. LPS (from E. coli serotype 0127:B8; Sigma) (50 μg) in 20 μL of saline (0.9% NaCl) was administered via intranasal instillation. The control group consisted of mice without any treatment because simple administration of vehicle (saline) is enough to induce lung inflammation. Twenty-four hours after LPS administration, the mice were sacrificed for biodistribution studies and the lungs were saved for histopathologic analysis.
