CYANIDE ENCEPHALOPATHY PRODUCED BY INTRAVENOUS ROUTE

Abstract
Rats that received a single intravenous treatment with potassium cyanide showed brain lesions entirely similar to those produced by a single exposure to hydrogen cyanide. The production of selective white matter lesions did not depend on repetitive cyanide treatments, but rather on maintenance of optimal depth and duration of intoxication. This evidence suggests that the effect of cyanide on white matter is direct rather than indirect. Concomitant administration of 02 did not influence the results.
