    Notes: Summary The cell content of a CSF sample of a patient with mumps meningoencephalitis was divided into 4 portions and cultured in vitro. The first two cultures were stained 24 hrs later with fluorescein conjugated sera by the indirect method. The cells brought together with the serum containing antibodies against mumps virus showed a bright yellowish fluorescence; the controls were free. The diagnosis of mumps meningoencephalitis could be confirmed by serologic methods and by virus isolation. The two remaining cultures were stained 2 weeks later in the same way. A monolayer of epithelial cells had grown out. By fluorescence it could be demonstrated that these cells still contained large amounts of virus material.

    Description / Table of Contents: Zusammenfassung Das Verteilungsmuster der DNase-Aktivität1 im Urin von Normalpersonen und X.p.-Patienten wurde mit einem mikro-disk-elektrophoretischen Verfahren untersucht. Bei saurer Inkubation sind 4 distinkte Aktivitätsbanden im Normalurin nachweisbar. Urin von X.p.-Patienten zeigt eine deutliche Verminderung der 2.–4. Bande, wobei die Veränderung der 3. Bande besonders auffällig ist. Es wurde ferner untersucht, wie sich das Verhalten verändert, wenn statt nativer DNA denaturierte als Substrat angeboten und wenn die zweiwertigen Ionen durch EDTA komplexiert wurden. Eine Aktivitätsverminderung ist nicht auf das Auftreten von Inhibitoren zurückzuführen, sondern wahrscheinlich durch eine Konzentrationsverminderung an Enzym verursacht.
    Notes: Summary The distribution pattern of desoxyribonuclease (DNase) activity1 in the urine of healthy subjects and xeroderma pigmentosum (X.p.) patients has been examined by micro disc electrophoresis. When incubated at pH 5.0, four distinct bands of DNase activity are shown in normal urine. In urine of X.p. patients a significant decrease of the second to fourth band can be observed. The change of the third band is extremely obvious. Further to the influence of native DNA, denaturated DNA and EDTA on the pattern of DNase activities were studied. The decrease of DNase activity in X. p. urine is not due to the presence of an inhibitor but is rather caused by lower enzyme concentrations.
