Effect of Gamijinhae-tang (GJHT) extract on cytokine in BAL fluid. The levels of IL-1b and IL-6 in BAL fluid were determined by ELISA. Control: saline treated, ALI: PPE (porcine pancreatic elastase) + LPS (lipopolysaccaride) treated, ALI + Dexa: ALI + dexamethasone (Dexa), ALI + GJHT: ALI + GJHT (Gamijinhae-tang). Data are expressed as the mean ± S.E.M. (## p < 0.01 versus control and *p < 0.05, **p < 0.01 versus ALI; n = 5-7).
