2. Long-wave ultraviolet radiation (UVA1) and visible light : therapeutic and adverse effects in human skin
Sammanfattning : We studied the effects of repetitive low-dose UVA1 radiation and visible light in normal sunshielded skin, using immunohistochemical staining for p53, p21WAF-1, bcl-2, Ki67 and cyclin A. An increased expression of Ki67 after UVA1 and visible light were observed as a sign of increased proliferation. LÄS MER
