Abstract

This study analyzed neurons and neuroglia morphology, and pia mater defensive cells from canine spinal cord cervical, thoracic, and lumbar regions. Hematoxylin-eosin (HE), Masson’s trichrome (MT), silver and anti-peroxydase peroxydase (APP) stains were used. By MT, neurons with acidophilic nucleus and basophilic cytoplasm were observed. HE showed neurons with basophilic nucleus and acidophilic cytoplasm. Irregularity of cytoplasmatic processes, large, round or oval nucleus, pale-stained, and one or more nucleolus was also noted. By APP, astrocytes were visualized with brown cytoplasm and blue-purple nucleus, showing fibrous astrocytes with long and less ramified processes, and protoplasmic astrocytes with short and ramified processes. Silver stain showed oligodendrocytes with round cell body and microglia with small and thin cell body, in both white and gray matter. Ependimary cells showed ciliated cylindrical epithelium, and the defensive cells found were mature neutrophiles and eosinophiles
