    Notes: Summary The sera of 21 psoriatics treated by selective ultraviolet phototherapy (SUP) for 1–7 months were screened for IgG- and IgM-anti-DNA antibodies and antinuclear antibodies (ANAs) by standardized ELISA and the indirect immunofluorescence technique. No patients developed IgG-antibodies against native DNA under SUP, but two patients increased their IgM-antibody titers five- and tenfold, respectively. The IgG- and IgM-anti-single-stranded-(ss)DNA antibody titers remained unaltered in 38% and 57% of the patients. In 43% and 24%, respectively, they rose to a maximum of three times their original; and in 20% they decreased to a minimum of 40% of their pretherapeutic titers. After 1 month therapy no patient had produced ANAs, but all three patients showing ANAs before therapy had increased titers (one titer step). These remained on the elevated level or were even further increased by one-titer step during progressive therapy. Two patients out of 14 developed low titers of IgM-(1:20) or IgA-(1:40)ANAs against deoxyribonucleoprotein (DNP), initially after 3 months of irradiation; in one of them IgG-ANAs (titer 1:10) against DNP were additionally formed after 6 months of therapy. Our results suggest that lesions in DNA and DNP generated by SUP trigger an immune response to nuclear antigens.

    Description / Table of Contents: Summary Tyrosinase mRNA produced by melanoma cells can be detected by reverse transcriptase-polymerase chain reaction (rt-pcr) with fine-needle tissue punctures. Fine-needle punctures from six suspected skin and lymph node metastases in three patients with malignant melanoma were analysed via rt-pcr for tyrosinase mRNA. All the suspected metastases were surgically removed and histologically examined separately. In each case the rt-pcr results and the histological diagnosis corresponded. This less invasive and highly sensitive method could prove to be a useful alternative in the diagnosis of melanoma metastasis.
    Notes: Zusammenfassung Melanozytäre Zellen unterscheiden sich in ihrem Metabolismus von anderen Zellen durch die Expression des Enzyms Tyrosinase. Bei 3 Patienten mit malignem Melanom konnte an 6 Feinnadelpunktaten von fraglichen Haut- und Lymphknotenmetastasen die Tyrosinase-mRNA mittels Reverser Transkription/Polymerasekettenreaktion (RT/PCR) nachgewiesen werden. Die Veränderungen wurden im Folgenden operativ entfernt und histologisch aufgearbeitet. Die Ergebnisse der RT/PCR korrespondierten jeweils mit der histologischen Diagnose. Diese wenig invasive und sehr sensitive Methode der Feinnadelpunktion mit anschließender molekularbiologischer Untersuchung könnte für die Diagnostik von Melanommetastasen als Alternative zur diagnostischen Exzision bzw. Aspirationszytologie bedeutsam werden.
