Figure 4

The expression of collagen I and collagen III in the different groups determined by immunohistochemistry. Image scale bar, 100 µm. Brown staining, target protein collagen I and collagen III; blue staining, nucleus. Data are presented as the mean ± standard deviation in the corresponding histogram. vs. the control group. Control: rabbit tracheal stenosis model without treatment; NS: rabbit tracheal stenosis model treated with penicillin; ERY: rabbit tracheal stenosis model treated with erythromycin; Budesonide: rabbit tracheal stenosis model treated with budesonide; Vorinostat: rabbit tracheal stenosis model treated with vorinostat.
