The effect of Gamijinhae-tang (GJHT) extract on goblet cell and musins. A) Mouse lung sections were stained with PAS (magnification × 400), B) goblet cell (%), and C) Muc5AC and Muc5B mRNA expression. Muc5AC and Muc5B mRNA expression were analyzed by quantitative real-time PCR. Expression levels of Muc5AC and Muc5B mRNA were normalized to GAPDH and expressed as the relative quantity to controls. 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). The statistic power for Muc5AC; p = 0.0039, F = 7.89, and R2 = 0.76, and for Muc5B; p = 0.0042, F = 7.70, and R2 = 0.75.
