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.

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.
