ABSTRACT
The paraplegic syndrome of bovines is a condition characterized by impairment of locomotion, hypoalgesia and finally death within 72 h. The pathogenesis of the syndrome has not been established. In the present work we determined the levels of monoamines and their metabolites in cerebro-spinal fluid and spinal cord of affected animals in order to investigate the functional state of these neurotransmitters. The content of the main metabolite of serotonin, 5-hydroxyindoleacetic acid, was elevated in the cerebro-spinal fluid and in the gray matter of the spinal cord of paraplegic bovines. Serotonin content in the spinal cord did not differ with respect to control animals, but was decreased in the cerebro-spinal fluid of affected animals. Modifications in the noradrenergic system were also observed, but were less consistent, for which reason further studies are needed. These observations indicate an increase in the turnover rate of serotonin in the paraplegic syndrome. The meaning of the described alterations is unknown at the moment
