    Description / Table of Contents: Zusammenfassung Bei 10 gesunden Menschen und 10 Patienten mit Leberzirrhose wurde der Serumeisen-Umsatz, die Ferrokinetik im Organismus, die Hämoglobinsynthese, die Halbwertzeit der Erythrozyten und die mittlere Reifungszeit des Erythrons mit Hilfe von59Fe untersucht. Der Eisenumsatz und die Hämoglobinsynthese waren bei der Leberzirrhose zwar signifikant erhöht, jedoch nicht so ausreichend, daß dadurch die Reduktion der Erythrozytenlebensdauer kompensiert wird. Die mittlere Reifungszeit des Erythrons war normal. Nach den vorliegenden Befunden konnten zwei Faktoren für die Anämie bei Leberzirrhose verantwortlich gemacht werden: die Hämolyse und die relative Knochenmarksdepression. Mit Hilfe der angewandten Methodik war es möglich, die Rolle dieser Faktoren bei allen untersuchten Patienten quantitativ aufzudecken.
    Notes: Summary Turnover of plasma iron, kinetics of iron through the body compartements, hemoglobin synthesis, red cell half life and mean effective erythron maturation time were studied, by using Fe59, in 10 normal subjects and 10 cirrhotic patients. Iron turnover and hemoglobin synthesis were significantly raised, but not sufficiently to compensate the red cell life span reduction. Mean effective erythron maturation time was normal. In conclusion two factor were responsible for the anemia: the hemolysis and a relative marrow depression. By the method used it was possible to discriminate quantitatively their importance in all the subjects investigated.

    Notes: Abstract Lidocaine and Bupivacaine inhibitin vitro 3H-TdR incorporation into peripheral lymphocytes, in a dose dependent ratio, either under PHA stimulus or not. Lidocaine added to cultures at various times from PHA stimulus show a reduced inhibition only when added after the 24th hour. This suggests a sensitizing action of PHA. Lidocaine effect on mitosis of doses between 2000 and 500 μg/ml was not completely reversible even when the drug was removed after only 15 min; between 200 and 50 μg/ml this effect is reversible. Lymphocyte viability by Trypan Blue exclusion is clearly unrelated to mitotic inhibition; it is however dose related. High Lidocaine and Bupivacaine concentration alter adhesion of cells to plastics and decrease lymphocyte aggregation by PHA. Electrophoretic mobility of lymphocytes incubated with 2000 μg/ml of Lidocaine is slower compared to controls; there is no change at 200 μg/ml. Local anaesthetics modify steric membrane structure reducing surface charge density. Increased Ca++ in the medium containing local anaesthetic increases lymphocyte stimulation index slightly only for Lidocaine and Bupivacaine doses, which neither alter membrane function nor interfere with lymphocyte viability nor electrophoretic mobility. Increased Na+ and K+ in the medium do not affect local anaesthetic action.
