Specific cytotoxic T-lymphocytes (CTL) will be expanded in vivo by low-dose interleukin-2 (IL-2). The expression vector used is the pcDNA3 HLA-B13 plasmid ; driven by a cytomegalovirus promoter. Leukemic cells are transfected by electroporation/ballistomagnetic transfer.

    Description / Table of Contents: Zusammenfassung Ein Verfahren der »cathodicstripping«-Voltammetrie wird beschrieben zur simultanen Bestimmung von Selen und Tellur im Bereich von 0,2–20 ppb Selen und 0,2–50 ppb Tellur. Die elektrolytische Anreicherung erfolgt potentiostatisch bei −0,4V (SCE) aus (NH4)2SO4-haltiger Grundlösung (pH 4,5) in Gegenwart von ÄDTA und CuCl2 an einem hängenden Quecksilbertropfen. Das Verfahren ist weitgehend störungsfrei und ermöglicht auch die Einzelbestimmung des Selens bzw. Tellurs in Gegenwart eines 104-fachen Überschusses des anderen Partners.
    Notes: Summary A “cathodic-stripping” voltammetric procedure for the determination of selenium and tellurium in the range of 0.2–20 ppb and 0.2–50ppb, respectively, is described. The electrolytical preconcentration on a hanging Hg-droplet is effected potentiostatically at −0.4 V (SCE) from a supporting electrolyte containing (NH4)2SO4 (pH4.5), in the presence of EDTA and CuCl2. The procedure is substantially free of interferences and enables also the single determination of selenium and tellurium in the presence of a 104-fold excess of the corresponding concomitant element.

    Description / Table of Contents: Zusammenfassung Wesentliches Problem einer Defektosteosynthese ist ihre Instabilität, hervorgerufen durch Biegebelastung der Steinmannägel in „falscher” Richtung zum Hauptkraftfluß. Im Zugstangenfixateur werden die Implantate in Zuganker umfunktioniert, in dem ihre Richtung der des Kraftflusses angenähert wird. Sie entstehen durch schräg zur Knochenachse gesetzte Schanz'sche Schrauben. Der Stabilitätsgewinn ist 5–20mal höher als bei konventionellen Montagen.
    Notes: Summary It is very difficult to stabilize a defective osteosynthesis of the lower extremity, which is necessary to prevent bone infection. Mainly responsible for the instability is the lack of bending stability of the transosseous nails which are loaded across their axle. In a newly developed model called the “tensile rod fixateur” (Labitzke and Henze 1979–1980) Schanz screws function as tensile rods. A defective osteosynthesis treated with this principle shows 5–20 times more stability than those treated in a conventional way.
