FLG causes acute pulmonary toxicity characterized mainly by cell injury and lung edema 24 h post exposure. a BALF total cell count; b BALF total protein; c LDH activity; d The lung wet/dry weight ratio used to evaluate the severity of lung edema. The symbol‘*’and‘**’indicates values that differed significantly from the control group at P ≤ 0.05 and P ≤ 0.01, respectively. Data are presented as mean ± standard deviation (n = 6)
