    Notizen: Abstract  Anticardiolipin antibodies (aCL) or lupus anticoagulants (LA) have been found to exert an inhibitory action upon the activation and function of protein C, a natural coagulation inhibitor. Recently an in vitro phenomenon called resistance to activated protein C (APC resistance) has been described as the most frequent cause of hereditary thrombophilia. In order to see whether a positive association of APC resistance with aCL exists we examined plasma of 162 consecutive outpatients referred for thrombophilia screening. Further, the IgG fraction was isolated from plasma of two aCL-positive and LA-negative patients and of two aCL-negative healthy subjects by means of protein A affinity chromatography. Each of these isolates was mixed with normal plasma, and the APC resistance was assayed; 25/162 (15.4%) patients had confirmed abnormal APC resistance. Only 1/25 (4.0%) APC resistance-positive patients and 11/137 (8.0%) APC resistance-negative patients had positive IgG- and/or IgM-aCL (p=0.5, nonsignificant). In the in vitro test system the APC resistance ratio remained unaffected after addition of normal IgG or aCL-IgG fraction in the tested normal plasma and did not deviate from the range of buffer controls. These data do not suggest any association of aCL with abnormal APC resistance. aCL-IgG fractions from aCL-positive and LA-negative plasmas do not interfere with the APC resistance test system in vitro in low concentration.

    Proliferation of tumor spheroids after shock-wave treatment (1994)

    Notizen: Abstract Multicellular tumor spheroids (MCTS) grown from the bladder cancer cell line RT112 and from the prostate cancer cell line PCA were exposed to 200 or 800 electromagnetically generated focused ultrasound shock waves. RT112 cells showed a distinct but transient decrease in proliferation whereas the effect of PCA cells was less pronounced. Flow-cytometric measurements of DNA content and Ki67 expression revealed no significant changes in the cell cycle distribution. The capacity of RT112 cells exposed to 800 shock waves to re-grow as MCTS was markedly decreased, indicating an alteration of intercellular adhesion.

    Notizen: In Gegenwart eines großen SO2-Überschusses ist die quantitative polarographische COS-Spurenbestimmung in Diäthylamin/Äthanol als Grundlösung möglich, wenn das SO2 ganz oder teilweise durch Braunstein oder Silicagel gebunden wird. COS und H2S lassen sich gemeinsam bestimmen, wenn die SO2-Menge in 25 ml Grundlösung etwa 5 mg SO2 nicht übersteigt. Die quantitative polarographische Analyse von H2S-Spuren in Gegenwart eines großen SO2-Überschusses gelingt in Hydrazinhydrat/Äthanol als Grundlösung.
