    Notes: Summary The object of the present study was to analyse the ultrastructure of Opalski cells, obtained in tissue culture according to the method described by Mossakowskiet al. (1970). The electron microscopic picture of the Opalski cells was characterized by scanty endoplasmic reticulum and Golgi apparatus and a greatly reduced number of mitochondria, as compared with glial cells cultured in vitro. Their cytoplasm contained two types of spherical bodies, one of which corresponded to lysosome-like bodies; the second one, in the authors' opinion, represented an accumulation of mucopolysaccharide substances. The ultrastructural picture of Opalski cells corresponded well with their previously described histochemical properties.

    Description / Table of Contents: Zusammenfassung Die Absicht der Experimente war es, in Gliagewebskulturen die für die Wilsonsche Krankheit und für die hepathogene Encephalopathie typischen Veränderungen zu erzeugen. Die Experimente wurden an Kleinhirnzellkulturen von neugeborenen Ratten durchgeführt. Das Standardmedium wurde ergänzt mit: 1. Serum von Patienten mit Wilsonscher Krankheit, 2. Serum von Patienten mit Leberkoma, 3. Kupferacetat, 4. Ammoniumchlorid. In allen Versuchsgruppen wurden typische morphologische Veränderungen an den Gliazellen beobachtet. Diese nahmen die Form von Alzheimer-Zellen des Typs I und II, Opalski-Zellen und intermediären Zellen an. Histochemische Abweichungen zeigten sich in Form von Anhäufung neutraler und saurer Mucopolysaccharide im Cytoplasma der Opalski-und Intermediärzellen mit einem begleitenden Abfall der SDH-und GDH-Aktivität sowie ein einer Zunahme der G6PDH und sauren Phosphatase-Aktivität. Der mögliche pathogenetische Mechanismus dieser Veränderungen wird diskutiert. Die Autoren vermuten, daß sowohl Kupfer als auch Ammoniak eine Schädigung der intracellulären Enzymketten des Kohlenhydratstoffwechsels bewirken. Diese Schädigung führt zu einer Anhäufung von Mucopolysacchariden in den Gliazellen.
    Notes: Summary The object of the experiments was to obtain changes typical for Wilson's disease and hepatogenic encephalopathy in glial tissue cultures. The experiments were carried out on newborn rat cerebellum tissue cultures. The standard medium was supplemented with: 1. Serum from patients with Wilson's disease, 2. serum from patients with hepatic coma, 3. copper acetate, 4. ammonium chloride. In all experimental groups typical morphological changes of glial cells were observed. These took the form of Alzheimer cells type I and II, Opalski cells, and intermediate cells. Histochemical abnormalities appeared in the form of an accumulation of neutral and acid mucopolysaccharides in the cytoplasm of Opalski and intermediate cells, with an accompanying decrease of SDH and GDH activity, and an increase in G-6PDH and acid phosphatase activity. The possible pathogenic mechanism of the above changes is discussed. The authors suggest both copper and ammonia cause damage in the intracellular enzymatic chains involved in carbohydrate metabolism. This damage leads to an accumulation of mucopolysaccharides in the glial cells.
