Representative images for PAS staining in the cornea and conjunctiva. No PAS-staining cells were found in the corneas of the three groups (A, left-hand images). PAS staining of the cornea and forniceal conjunctiva showed that, after 14 d of treatment, the goblet cells were abundantly present in the conjunctival fornix of the PBS-treated eyes but almost disappeared after PM2.5 treatment (A right-hand images). The average number of PAS-positive cells in the conjunctiva was significantly lower than that in PBS-treated eyes on day 14 (P < 0.05, B). The data are presented as the mean ± the SD, n = 5. * P < 0.05 vs. control, vP < 0.05 vs. PBS.
