Effects of SM vapor on expression of PCNA in the rabbit cornea. Panel A: Histological sections, prepared from control (CTL) corneas and corneas 3, 14, and 28 days post-SM, were stained with an antibody against PCNA. Antibody binding was visualized using a Vectastain Elite ABC kit. One representative section from 4 rabbits/exposure group is shown (n=4 rabbits/exposure). Ep, epithelium; S, stroma. Panel B:Control cornea epithelial cells and epithelial cells from corneas 3, 14, and 28 days post-SM expressing PCNA were enumerated (15–20 fields/cornea). Each bar represents the mean ± SE (n = 4). *Significantly different (p≤0.05) from CTL.
