Experimental ‘hindbrain related’ syringomyelia: some mechanisms of spinal cord damage
Journal Title: Journal of Neuroscience and Neurological Disorders - Year 2017, Vol 1, Issue 1
Abstract
Syringomyelia in combination with inherent or acquired hindbrain abnormalities is the non seldom and at the same time controversial issue. Purpose: The etiology and pathogenesis creates a lot of discussion. Methods: Experimental syringomyelia was induced in 20 anesthetized rabbits by injecting 0.5 ml of 25% kaolin suspension into the cisterna magna. Six rabbits with puncture and injection sterile saline NaCl were used as a control. The animals were sacrificed 1, 2, 4 and 6 months after the kaolin injection. Four hydrocephalus rabbits were sacrificed in 17 hours after the puncture of lateral ventricle with injection of solution of colloidal gold labeled human albuminum. The sections of the brain and spinal cord were stained with hematoxylin and eosin by Nissle and Marchi methods and with immunogold technique. Retropharyngeal lymph nodes of the animals were examined by electron microscopy. Conclusion: Our observation showed that water hammer effect and internal destruction of the spinal cord may lead to continuous antigen stimulation of regional lymph nodes and play an important role in pathogenesis of experimental syringomyelia.
