Table 2 Changes in SOD activity after UVB irradiation with various compounds. *p Indicates a significant difference between the treatment and normal groups at p < 0.05, **p indicates a significant difference between the treatment and normal groups at p < 0.01, and ##p indicates a significant difference at p < 0.01 for the model and normal groups. The difference between each well was calculated as (survival rate of each well in each group/mean survival rate of the model group) −1.
