Fig. 2. Assessment of effect of BS012 on histological examination of lung tissues by H&E staining. (A) H&E-stained sections of lung tissues (original magnification ×200). (B) Measured the thickness of bronchial epithelium. Data are presented as mean ± SEM (n=5 per group). *** Significantly different (p<0.001) from Control group. #, ## Significantly different (p<0.05, 0.01) from OVA group. Assessment of effect of BS012 on goblet cell hyperplasia in lung tissue by PAS staining. (C) PAS staining results of the lung tissues (original magnification ×200), mucus is stained as a purple color. (D) Quantitative analyses of PAS positive cells in bronchial. Data are presented as mean ± SEM (n=5 per group). *** Significantly different (p<0.001) from Control group. ### Significantly different (p<0.001) from OVA group.
