[Psoriasis. Sodium, potassium, chloride--analysis in sweat, saliva and urine--selective ultraviolet phototherapy]

It has been recognised that the sweat (extracellular area) excreted from those affected with psoriasis contains twice the amount of sodium and four times the amount of potassium in comparison to those not affected with psoriasis. According to Saalmann, after HUV therapy (SUP) there is a significant reduction of the saliva sodium content (intercellular area) not only with psoriasis patients, but with all other patients receiving radiation therapy as well. This result has never before been described in the literature. Therefore, on the one hand, completely new aspects of psoriasis and therapy can be recognized, and on the other hand, of the effects of SUP.
