Zusammenfassung
Es wird berichtet über die Morphologie der „intranuclear bodies” in Gliomen des Menschen.
Das elektronenoptische Bild solcher „intranuclear bodies” variiert je nach dem Vorhandensein der unterscheidbaren strukturellen Komponenten. Danach lassen sich vier Typen differenzieren:
-
Typ I.
Kleine, fädige, von einer optisch leeren Zone umgebene “intranuclear bodies“.
-
Typ II.
Größer als Typ I mit einem granulären Kern, der konzentrisch von einer filamentösen Schicht umgeben ist.
-
Typ III.
“Intranuclear bodies” mit einem dichten granulären Kern und filamentös strukturierter umgebender Schicht.
-
Typ IV.
Größter “intranuclear body”, der alle drei Komponenten, Kern, granuläre und filamentöse Außenschicht enthält.
Summary
The morphology of intranuclear bodies observed in human gliomas, is described. The ultrastructural picture varies according to the number of structural components present in every intranuclear body. On this basis they are classified into four types:
-
Type I.
Small, filamentous intranuclear body, surrounded by a clear halo.
-
Type II.
Intranuclear body larger than type I, showing a filamentous periphery concentrically surrounding a granular center.
-
Type III.
Intranuclear body with a filamentous concentric layer around a granular core.
-
Type IV.
The largest intranuclear body showing the same three components: core, granular and filamentous layers.
