(a) Apoptotic cells in the epidermis of each group, stained by TUNEL staining and detected by light microscopy with ×400 magnifications. (A) Control; (B) UVB group; (C) UVB + vehicle group; (D) UVB + 5.0 IU/mL SOP group. (i) 8 h; (ii) 24 h; (iii) 48 h; (iv) 72 h. (b) The number of apoptotic cells in the epidermis of each group. Compared with UVB group, the number of apoptotic cells in UVB + 5.0 IU/mL SOP groups at 8, 24, 48, and 72 h was significantly decreased (). Stained by TUNEL staining and detected by light microscopy with ×400 magnifications. when compared with the UVB group.
