Nachweis und Verteilung der Enzyme: β-d-Glucuronidase, β-d-Galaktosidase, β-d-Glucosidase und Arylsulfatase in Neurinomen

Zusammenfassung In 17 Neurinomen wurden Verteilung und Aktivität der hydrolytischen Enzyme -d-Glucuronidase, -d-Glucosidase, -d-Galaktosidase und Arylsulfatase untersucht.Die höchste Aktivität der Enzyme zeigten die verfetteten Neurinome. Es bestand eine enge Beziehung zwischen Lipidablagerung und Fermentaktivität.Daraus wurde geschlossen, daß die im Neurinom gebildeten Markscheidenlipide unter Mitwirkung der untersuchten Hydrolasen abgebaut werden.

Demonstration and distribution of the enzymes: -d-glucuronidase, -d-galactosidase, -d-glucosidase, and arylsulfatase in neurinomas

Summary In 17 neurinomas, distribution and activity of the hydrolytic enzymes -d-glucuronidase, -d-glucosidase, -d-galactosidase, and arylsulfatase were examined. Highest enzyme activity was seen in neurinomas stuffed with lipid material. There was close relationship between lipid deposition and enzyme activity. From these findings it was concluded that myelin lipids formed in neurinomas are degradated by means of the examined hydrolases.
