Calycosin Alleviates Injury in Airway Epithelial Cells Caused by PM 2.5 Exposure via Activation of AMPK Signalling

Figure 1

Calycosin inhibits PM 2.5-induced cell damage in vitro. (a) Absorbance of B2B cells at different calycosin concentrations. The P value between 0  μm group and 500  μm group for “^∗” is 0.0356 < 0.05; the P value between 0  μm group and 1000  μm group for “^∗∗” is 0.0097 < 0.01. (b) Absorbance of B2B cells treated with PM 2.5 at different calycosin concentrations. The P value between 0  μm group and 50  μm group for “^∗” is 0.0180 < 0.05; the P value between 0  μm group and 100  μm group for “^∗∗” is 0.0092 < 0.01. (c) Activity and number of B2B cells treated with or without PM 2.5 at different calycosin concentrations observed under a microscope at 40 × magnification.
