    Description / Table of Contents: Zusammenfassung Das “symmetrische Höhenindexsystem” (sli) zur Zahlendarstellung vereinfacht die Überwachung der Rechengenauigkeit und vermeidet overflow—oder underflow—Probleme. In dieser Arbeit werden die praktischen Vorzüge des Systems am Beispiel des Graeffeverfahrens vorgeführt.
    Notes: Abstract The symmetric level-index,sli, system for representing numbers eases the monitoring of precision while avoiding the problems associated with overflow and underflow. In this paper the practical benefits of the system are displayed, using the root-squaring method of Graeffe as a vehicle.

    Notes: Summary Nifedipine (10 mg), nisoldipine (10 mg) and nitrendipine (20 mg) were given orally to 8 normal volunteers in a placebo controlled, double blind, crossover study. Blood pressure (BP), pulse (P) and systolic time intervals (STI) were recorded at time 0, 30, 60, 90, 120 min after drug administration. Adverse effects were also recorded. There was a fall in BP, pre-ejection time (PEP), PEP/LVET (left ventricular ejection time) and electro-mechanical systole index (QS2 index), and a rise in LVET index in response to the three active drugs compared with placebo. All active drugs, but not placebo, were associated with adverse effects.

    Notes: Summary The effects of pentoxifylline on filterability of normal red blood cells (RBCs) and their adhesiveness to cultured endothelial cells were investigated. 1. In a balanced randomized and double blind trial, six healthy volunteers received 400 mg pentoxifylline or matching placebo 2 h before blood samples were taken. Filterability of RBCs of the subject while on pentoxifylline was significantly increased at 25 °C and 18 °C. 2. Lowering of the filteration temperature to 18 °C significantly decreased filterability of RBCs. 3. In vitro studies showed that 12 µg/ml pentoxifylline significantly increased RBC filterability and also partially prevented the effect of decreasing temperature on RBC filterability. 4. 12 µg/ml pentoxifylline significantly decreased the adherence of normal RBCs to cultured endothelial cells. Our results suggest that in addition to increasing filterability of RBCs, pentoxifylline also decreased the adherence of RBCs to endothelial cells and this may contribute to its therapeutic effect.
