(a) Cyclobutane pyrimidine dimers- (CPDs-) positive cells in the epidermis of each group, stained by immunohistochemical 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 CPDs-positive cells in the epidermis of each group. Then, 8, 24, 48, and 72 h after ultraviolet B (UVB) irradiation, the number of CPDs-positive cells in UVB + 5.0 IU/mL SOP groups was significantly decreased compared with UVB group (); stained by immunohistochemical staining and detected by light microscopy with ×400 magnifications; when compared with the UVB group.
