[Psoriasis vulgaris--decrease of serum immune complexes following photochemotherapy (author's transl)]

By means of a polyethylene glycol precipitate method [6] circulating immune complexes were examinated in increased concentration in 56 percent of the sera from psoriatic patients. The effect of photochemotherapy with external administration of 8-methoxypsoralen followed by irradiation with UVA was investigated. In 12 of 13 cases the serum immune complex concentration after the therapy was normal.
