Sažetak

The highly toxic nature of tabun has been known for many years, but there are still serious limitations
to antidotal therapy. In this study, we used rats as an experimental model to evaluate the efficiency
of bispyridinium para-oxime K203 as therapy against tabun poisoning as well as to examine if induction
of oxidative stress is linked to organophosphate toxicity. K203 showed high potency in counteracting
tabun poisoning. Either alone or in combination with atropine, this oxime significantly increased cholinesterase
activity at 0.5 and 1 h compared to untreated rats poisoned with tabun. Simultaneous measurements
of markers of oxidative stress (lipid peroxidation and superoxide dismutase) showed that tabun poisoning,
but also therapy (oxime alone or oxime plus atropine) applied immediately after tabun poisoning, could
generate free radical species that may cause oxidative stress in rats. (doi: 10.5562/cca1811)
