    Notes: Summary A hydrocephalic-hydromyelic condition was induced in adult cats by causing the closure of the lateral apertures with intracisternal injections of kaolin. After displaying the symptoms characteristic of increased intracranial pressure, which lasted about 10–14 days but varied somewhat in intensity from animal to animal, the cats recovered. From approximately the 2nd post-operative week onward, a distended central canal was revealed by ventriculography; subsequently cavities developed in the tissue of the cord that communicated with the canal. Most cavities were located dorsal to the canal. The surfaces of the distended canal and the cavities showed that in ventral areas the ependyma streched but remained intact, whereas in dorsal areas it ruptured, exposing the nerve fibers to the cerebrospinal fluid (CSF). In cats which had been hydrocephalic for up to 2 years the walls of the cavities were covered by gliotic scar tissue; the nerve fibers were no longer exposed directly to the CSF.

    Description / Table of Contents: Zusammenfassung Die Wand des Zentralkanals im Rückenmark der weißen Ratte enthält zahlreiche Basalmembranlabyrinthe; ihre Zahl nimmt in caudaler Richtung deutlich zu. Die Perjodsäure-Bisulfit-Aldehydthionin-Färbung (Specht) gestattet ihren lichtmikroskopischen Nachweis. Die Labyrinthe stehen in Verbindung mit den Basalmembranen der kanalnahen Kapillaren. Sie können auch elektronenmikroskopisch identifiziert werden; ihre Struktur gleicht der der Basalmembranen der Gefäße. Die funktionelle Bedeutung der Basalmembranlabyrinthe wird diskutiert.
    Notes: Summary The wall of the central canal of the spinal cord of the white rat contains numerous basement membrane labyrinths, their number increasing towards the end of the canal. The period-acid-bisulfit-aldehydethionine-method (Specht) permits their light microscopic finding. They are in connection with the basement membranes of the capillaries situated near the canal. The basement membrane labyrinths can be identified by electron microscopy; their structure is similar to that of basement membranes of the capillaries. The functional significance of these structures is discussed.
