Summary
In 8 cases, the following enzymes were studied in the dendritic swellings and torpedoes of Purkinje cells of cerebellum: succinic dehydrogenase, cytochrome oxidase, lactic dehydrogenase, NAD-diaphorase, alkaline phosphatase, acid phosphatase, acetyl cholinesterase and nonspecific cholinesterase. Activity of the oxidative enzymes was always extremely high in the dendritic swellings, but varied greatly among cases in the torpedoes; 4 cases showed very weak activity of oxidative enzymes in torpedoes, while 4 other cases showed an intense reaction. Dendritic swellings and torpedoes exhibited no alkaline phosphatase, acetyl cholinesterase, or nonspecific cholinesterase activity.
Zusammenfassung
In Dendritenanschwellungen und Torpedos der Purkinje-Zellen des Kleinhirns von 8 Fällen wurden die folgenden Enzyme untersucht: Bernsteinsäure-Dehydrogenase, Cytochrom-Oxidase, Milchsäure-Dehydrogenase, NAD-Diaphorase, alkalische Phosphatase, saure Phosphatase, Acetylcholinesterase und unspezifische Cholinesterase. Die Aktivität der oxidativen Enzyme war in den Dendritenanschwellungen immer sehr hoch, in den Torpedos aber von Fall zu Fall sehr unterschiedlich: 4 Fälle zeigten nur sehr geringe Aktivität, die 4 anderen jedoch eine sehr intensive Reaktion. Die Dendritenanschwellungen und Torpedos zeigten keine Aktivität der alkalischen Phosphatase, Acetylcholinesterase oder unspezifischen Cholinesterase.
