Abstract

Recent studies have shown that oral vanadate (V5+) administration results in behavioral toxicity in rats. The chelating agent Tiron (sodium 4,5-dihydroxybenzene-l,3-disulfonate) is an effective antidote in the removal of vanadium from vanadium-loaded rats. In this study, the protective activity of Tiron on vanadate-induced behavioral toxicity was evaluated in adult rats. Intraperitoneal treatment with Tiron at 235 or 470 mg/kg was initiated after 6 wk of oral sodium metavanadate administration (16 mg/kg/d) and continued for 2 wk. Although vanadate exposure did not result in a significant reduction in the general activity of the animals in an open field, a lower active avoidance acquisition could be observed. However, the vanadate-induced behavioral deficit was reverted by Tiron administration at 470 mg/kg. The present results suggest that Tiron may protect, at least in part, against metavanadate-induced behavioral toxicity.
