Summary
In the caryoplasm of various organs of the cat structures of the type of granular sphaeridies are regularly observed, which consist of a filamentous externum and a granular internum. In the cells of the lymphatic system in many of these sphaeridies inclusions of rather electronlucent material are found, which are arranged in a crystal-like pattern. It is suggested that these inclusions of the sphaeridies are composed of protein, which is produced in the nucleus.
Zusammenfassung
In verschiedenen Organen der Katze sind regelmäßig Karyoplasmadifferenzierungen vom Typ der granulären Sphaeridien mit einem filamentösen Externum und einem granulären Internum zu beobachten. In den Zellen des lymphatischen Systems weist ein Teil dieser Sphaeridien ca. 0,3 μ große, nur wenig elektronendichte Einschlüsse mit kristalloider Struktur auf. Es wird angenommen, daß es sich dabei um Protein handelt, das im Kern synthetisiert wird.
