Bromethalin-dosed cats developed a toxic syndrome characterized by ataxia, focal motor seizures, vocalization, decerebrate posture, decreased conscious proprioception, recumbency, depression, and semicoma. Bromethalin-dosed cats were euthanatized if seizure activity or hindlimb paralysis developed. Survival times were 48 hours (cat No. 1), 89 hours (cat No. 2), 90 hours (cat No. 3), and 97 hours (cat No. 4). Control cats (cat Nos. 6\u201310) and one bromethalin-dosed cat (cat No. 5) were euthanatized on day 20 after dosing. Spongy change (edema\u2014characterized by the formation of vacuoles in extracellular spaces and myelin lamellae), hypertrophied fibrous astrocytes, and hypertrophied oligodendrocytes were observed in the white matter of the cerebrum, cerebellum, brain stem, spinal cord, and optic nerve of all bromethalin-dosed cats. Spongy change occasionally extended into contiguous cerebellar Purkinje cell layer and cerebral cortical gray matter. The severity of lesions varied among cats but was most pronounced in cat No. 5 (480 hours after dosing). A leukocytic inflammatory response, gitter cell (macrophage) response, or axonal degeneration was not observed in the vacuolated areas. Ultrastructural findings included separation of myelin lamellae at the interperiod lines with the formation of intramyelinic vacuoles (intramyelinic edema), rupture and coalescence of intramyelinic vacuoles into larger extracellular spaces (spongy change), and pronounced cytosolic edema of astrocytes and oligoden-droglial cells.<\/jats:p>","DOI":"10.1177\/030098589202900206","type":"journal-article","created":{"date-parts":[[2010,3,8]],"date-time":"2010-03-08T17:19:33Z","timestamp":1268068773000},"page":"139-144","source":"Crossref","is-referenced-by-count":54,"title":["Neuropathologic Findings of Bromethalin Toxicosis in the Cat"],"prefix":"10.1177","volume":"29","author":[{"given":"D.
