Figure 5. NF-κB expression in corneal epithelia. Eyes were given vehicle alone (A) or treated with AST eye drops before UV exposure (B); control subjects were not irradiated with UVB (C). The mean values of NF-κB positive cells (yellow) in corneal epithelial were summarized (D). Expression of NF-κB was significantly downregulated in AST-treated mice after UVB irradiation (p<0.05).
