[A new UV-B irradiation unit. Experiences with psoriasis vulgaris with low dosage UV-B irradiation and local cignoline use].

We present technical and clinical experiences with a modified scheme of Ingram treatment using a new UV-B phototherapy unit. In addition to application of anthralin, eleven patients suffering from psoriasis vulgaris have been treated by means of this cabinet equipped with 40 UV-B lamps (Sylvania STF 756085 W UV 6). In a bilateral comparative study, we investigated the therapeutic results of standard increase of the UV-B doses and constant low UV-B dose (0.150 J/cm2), respectively. We discuss our results and therapeutic consequences of this therapy.
