Effects of topical rIL-20 on inflammatory changes induced by central corneal epithelial abrasion. Representative photos of limbal vessels at 24 hours after corneal epithelial abrasion in mice treated topically with PBS (A) or rIL-20 (B). Stained tissues showing vessels (red) with extravasating platelets (green) (A, B), and showing arterioles (▶) and venules (↓) with diameters marked (lines). Data on vessel diameters are plotted (C, D, n=4, * p<0.05 and ** p<0.05) and data on platelet and neutrophil extravasation are plotted. (E, F, n=4, *** p<0.001)
