The mechanisms that lead to hair loss in AA are still unclear. An aberrant pattern of cytokine expression of the T- helper Th{u2160} cell type has been detected. So far, {u2160}FN- gamma, interleukins, TNF- alpha, are cytokines that are well known to play a major role in the pathogenesis of the disease. To determine the efficacy and safety of using the phototoxic doses of ultraviolet A (UVA) after application of topical 8- methoxypsoralen in the treatment of extensive and resistant cases of AA UR - http://172.23.153.220/th.pdf ER -
