Inhibition of pulmonary fibroblast proliferation by CAE: primary pulmonary fibroblasts treated with CAE at various concentrations for 48 h. The density of pulmonary fibroblasts was adjusted to 1 × 10⁵/ml, and the serum concentration was 5%. CAE was dissolved by DMSO, and the concentration of DMSO in each solution is less than 0.1%. (a) MTT analysis of inhibiting pulmonary fibroblast proliferation by CAE. All data are expressed as mean ± SD (n = 6). ^∗P < 0.05 versus normal mice, ^∗∗P < 0.01 versus normal mice. (b) IC50 value of CAE inhibitory was with respect to the two kinds of pulmonary fibroblasts proliferation. All data are expressed as mean ± SD (n = 6).
