    Description / Table of Contents: Zusammenfassung Bei 31 gesunden Kontrollpersonen sowie 63 Patienten mit Digitalistherapie wurden die Zink-, Natrium-, Kalium- und Magnesiumkonzentrationen im Plasma und in den Erythrozyten bestimmt. In den Erythrozyten der mit Digitalis behandelten Patienten zeigte sich neben der von unserer Arbeitsgruppe bereits beschriebenen Zunahme der Natriumkonzentration ein deutlicher Anstieg des Zinkgehaltes. Die intraerythrozytären Kalium- und Magnesiumkonzentrationen sowie die analysierten Plasmaparameter wiesen keine Abweichungen von der Norm auf. Es wird diskutiert, daß die erhöhte Zinkkonzentration möglicherweise ebenfalls auf einer Digitalis bedingten Störung des transmembranen Ionentransportes beruht.
    Notes: Summary Determinations of zinc, sodium, potassium and magnesium in plasma and red blood cells were performed in 31 controls and 63 patients treated with digitalis. In digitalized patients sodium and zinc concentrations in red blood cells were significantly increased. The intraerythrocyte magnesium and potassium levels as well as all investigated electrolytes in plasma remained within the normal range. There was a close relationship between the increase of sodium and zinc content in red blood cells, indicating alterations in transmembrane transport mechanisms induced by digitalis therapy.

    Notes: Abstract The three-ridge clamAmblema perplicata was used to monitor two streams for the presence of zinc (Zn) and cadmium (Cd) derived from an industrial source. Clams were collected from a relatively uncontaminated area in one river and transported to four study sites in the two contaminated streams. The clams were placed into polyethylene cages and left in these streams for one week. Control clams were treated in a similar manner and left in the uncontaminated river. The highest mean concentration of Zn (956 µg/g dry wt) was found in the gill tissue of clams from the most contaminated site. The highest mean Cd concentration (18.6 µg/ g dry wt) was found in digestive glands of clams, also from the most contaminated site. Mean concentrations at contaminated sites were significantly higher than background and control levels; the findings suggest that these particular organs of clams may be useful in monitoring levels of Zn and Cd in other freshwater systems.
