Baicalin inhibited protein concentrations and cells counts in BALF and suppressed neutrophil infiltration in lung tissue. Mice were orally administered different concentrations (200, 100 and 50 mg/kg/day) of baicalin or PDTC (100 mg/kg/day) or vehicle for 7 days. On the seventh day, CVF (35 µg/kg) was injected via the tail vein for 1 h. Lung tissue and BALF were then collected. total protein concentration (A) and cells count (B) in BALF were assayed. The upper and middle lobes of the right lung were used to detect MPO activity in the lung (C). Results are expressed as mean ± SD (n = 12).**P < 0.01 was compared with the control group; ^#P < 0.05 and ^##P < 0.01 were compared with the model group
