Zusammenfassung

Junge Albinoratten beiderlei Geschlechtes, normale und adrenalektomierte Tiere, wurden auf synthetischen Diäten gehalten, in welchen entweder eine Anzahl von Vitaminen fehlte oder welche die Vitamine A, D, E sowie alle chemisch identifizierten B-Vitamine in genügenden Mengen enthielten.
