Cardiac and renal nitrosative-oxidative stress after acute poisoning by a nerve agent Tabun.

We hypothesized that Tabun poisoning, as well as other organophosphorous treatment, cause specific organs' oxidative changes that have not previously been substantiated investigated. In this regard, a marker for nitrosative-oxidative stress in the main haemodynamic organs (heart and kidney) could reveal the existence of such changes. In this study, for the first time we studied the nitrosative/oxidative stress in heart and kidney after acute Tabun (Ethyl N,N- Dimethylphosphoramidocyanidate) poisoning measuring by immunohistochemistry the expression of 3-nitrotyrosine--a marker for nitrosative-oxidative stress.
