Fig. 3From: Modified Qing-Zao-Jiu-Fei decoction attenuated pulmonary fibrosis induced by bleomycin in rats via modulating Nrf2/NF-κB and MAPKs pathwaysEffects of MQZJFD on the MMP9, collagen I and α-SMA expression in the lung tissues of BLM-treated rats. A–C Analysis of immunofluorescence staining of MMP9, collagen I and α-SMA expression in the lung tissue of the BLM-treated rats. D Representative immunoblot bands for collage I in the lung tissue of the BLM-treated rats. E Quantitative analysis of immunoblot bands. Data were presented as mean ± SEM (n = 4). #p < 0.05 and ####p < 0.0001 compared to the control group; *p < 0.05, **p < 0.01, ***p < 0.01 and ****p < 0.0001 compared to the BLM control group.
