Abstract
SynopisThe Golgi material of the neurones of the central nervous system of normal fowl and of birds affected with spontaneous cases of Neurolymphomatosis gallinarum (fowl paralysis) is described. Material was prepared according to the methods of Kolatchev and of Aoyama. The Golgi material of normal pyramidal cells of the cerebral cortex, the Purkinje cells of the cerebellum, the multipolar cells of the spinal cord, and the cells of the spinal ganglia, is present as rods, irregular bodies and filaments. Compact net-like Golgi material is present in the small cells of the spinal ganglia.In the neurones of fowl affected with Neurolymphomatosis gallinarum the Golgi material undergoes hypertrophy, followed by clustering of the Golgi elements and fragmentation. The intensity of the morphological changes and the number of neurones affected in a particular region of the central nervous system varies considerably, except in the spinal ganglia where all the cells examined exhibited marked changes. It was not possible to determine whether the changes were primary or secondary in nature. The literature of the subject is discussed.
