Summary
The perfusion of Berlin blue and trypan blue into the spinal subarachnoid spaces of dogs and sheep, during fixation, colored and distended the arachnoid proliferations, thus making them visible macroscopically. The findings were verified histologically. Dogs have small, simple villi while sheep have larger, more complex granulations. The distribution of the spinal arachnoid proliferations in these animals is recorded.
Résumé
Les espaces sous-arachnoïdiens du rachis sont identifiés macroscopiquement par perfusion de colorant chez le chiène le mouton. Les résultats ont été vérifiés histologiquement. Chez le chien on constate l'existence de villosités simples alors que le mouton a des granulations plus complexes.
Zusammenfassung
Es wurden Tierversuche an Hunden und Schafen mit Berliner-Blau und Trypan-Blau durchgeführt. Dabei wurde der Farbstoff in den spinalen Subarachnoidalraum gegeben. Die Ausdehnung und die Anfärbung der arachnoidealen Proliferationen wurden makroskopisch und histologisch beobachtet. Die Hunde zeigten kleine, angefärbte Granulationen, während die Granulationen der Schafe ausgeprägter und größer waren.
