Figure 2:

SM vapor induces structural changes in the rabbit cornea. Panel A: Histological sections, prepared from control (CTL) corneas and corneas 3, 14 and 28 d post-SM, were stained with H&E. Note the degradation of the stromal epithelium on day 3. One representative section from 4 rabbits/exposure group is shown. Ep, epithelial cells; S, stroma; arrows, keratocyte. Panel B: Histological sections, prepared from control (CTL) corneas and corneas 3, 14, and 28 days post-SM, were stained with H&E and analyzed for epithelial-stromal separation in the central corneas. Each bar represents the mean ± SE (n = 4). *Significantly different (p≤0.05) from CTL.
