Effect of oral supplements of CFW on conjunctival goblet cell population in PM2.5-induced DED rats. (A) Representative images of PAS-stained images of conjunctival sections (n = 4). Black arrows indicate the PAS-stained goblet cells, which appeared a strong violet color. Scale bar, 25 μm. (B) The numbers of goblet cells of 100 μm2 in five different sections were counted. The data are expressed as the means ± standard deviation (n = 10). *** p < 0.001 compared to control group. # p < 0.05 and ### p < 0.001 compared to the PM2.5-induced DED group.
