Effect of Gamijinhae-tang (GJHT) extract on immune cell profiles in BAL fluid. The number of neutrophils (p = 0.042, F = 3.00, and R2 = 0.36), macrophages (p = 0.0145, F = 4.00, and R2 = 0.43), lymphocytes (p = 0.0049 F = 5.00, and R2 = 0.49), and total cells (p = 0.0016, F = 6.68, and R2 = 0.58) were determined in BAL fluid. 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 number of cells ± S.E.M. (# p < 0.05, ## p < 0.01 versus control and *p < 0.05, **p < 0.01 versus ALI; n = 5-7).
