Figure 5. Protein carbonyl levels. Effect of epigallocatechin gallate (EGCG) eye drops on corneal protein carbonyl levels in ultraviolet B (UVB)-induced corneal oxidative damage in mice. *p<0.05 compared with the normal control. #p<0.05 compared with the UVB-treated alone group. All data are expressed as the mean ± standard deviation (SD; n = 10).
