Figure 1.

Acute lung injury was established in mice by LPS. (a) Mice were treated with LPS (5 mg/kg) through intratracheal injection. Bronchioles of 4- and 7-day experiment groups showed significant inflammatory responses. Bar = 20 μm. (b) Pulmonary edema was measured by dry-to-wet lung weight ratio. Data were measured as means ± SD (n = 3), *P < 0.05 versus 0 h.
