    Description / Table of Contents: Zusammenfassung Der klinische Verlauf zweier Patienten mit primärer Hypomagnesämie wird beschrieben. Bei einem Patienten, einem 5 Monate alten Säugling, wurden Magnesiumretention,-resorption,-Stuhlausscheidung und-Clearance gemessen. Die Retention (2,8%) und Resorption (7,8%) von Magnesium28 war deutlich erniedrigt im Vergleich zu Kontrollpersonen, die durchschnittlich 25% retinierten und 28% absorbierten. Zwischen den Retentionswerten der Eltern und Verwandten und denen der gesunden Erwachsenen bestand kein Unterschied. Der untersuchte Patient wurde erfolgreich mit Trimagnesiumdicitrat, entsprechend einer Dosis von 1,75 g Magnesium, behandelt.
    Notes: Abstract The clinical course of 2 patients with primary hypomagnesemia is reported. In one male patien, 5 months old, measurements of magnesium retention, intestinal absorption, fecal excretion and renal clearance were performed. The retention (2.8%) and absorption (7.8%) of 28-Mg were markedly reduced in comparison to controls (average retention 25% and average absorption 28%). The retention values of the parents and other relatives did not differ from those of healthy adults. The examined patient was successfully treated with trimagnesium dicitrate containing 1.75 g magnesium per day.

    Description / Table of Contents: Zusammenfassung Bei 3 Patienten mit Akrodermatitis enteropathica wurde mit Hilfe der Ganzkörpermessung nach oraler Applikation von 65Zn eine verminderte intestinale Zinkresorption gedunden. Dagegen war die Zinkelimination aus dem Körper normal. Die Zinkkonzentration im Serum war bei den Patienten stark erniedrigt. Alle klinischen Symptome verschwanden nach sehr hohen oralen Zinkdosen. Diese Befunde sprechen um so mehr für eine ursächliche Rolle des Zinks in der Pathogenese der Akrodermatitis enteropathica, als bei dieser Krankheit ultrastrukturelle Veränderungen in den Panethschen Zellen nachzuweisen sind [12], die auch beim Zinkmangel der Ratten gefunden wurden [Beitr. Path. 145, 336 (1972)].
    Notes: Abstract The intestinal resorption of zinc using 65ZnCl2 was estimated in 3 patients with acrodermatitis enteropathica, 2 healthy controls, and 3 heterozygotes. After oral application of 65Zn the whole body activity was measured by a whole body counter for 34 days. The 65Zn resorption of the patients amounted to 16, 42 and 30% of the applied dose, whereas the resorption values of the heterozygotes and the controls were in the range of 58 and 77%. The elimination of 65Zn from the body amounted to about 0.7% of the applied dose with no difference between controls and patients with acrodermatitis enteropathica. Before therapy the serum-zinc levels of patients were markedly decreased. After oral application of high doses of zinc aspartate (2×400 mg/day) all clinical symptoms disappeared within a week. The results point at a causal connection between zinc and the pathogenesis of acrodermatitis enteropathica. Ultrastructural alterations of the Paneth cells of the intestine are also shown in this disease [12] as have also been seen in Paneth cells of zinc deficient rats [Beitr. Path. 145, 336 (1972)].
