Özet

The oxidant stress-inducing effects of endosulfan, a chlorinated hydrocarbon insecticide of the cyclodiene group, have been examined following ig administration of single and repeated doses. A single dose of 30 mg/kg (similar to 30% LD(50)) endosulfan significantly (p < 0.001) increased the TBARS and, hence, the lipid peroxidation in cerebral and hepatic tissues of rats. Administration of endosulfan with doses of 10 or 15 mg/kg/d for 5 d has also induced lipid peroxidation significantly (p < 0.05). The same doses caused a significant alteration in glutathione redox status of cerebral and hepatic tissues, where total glutathione and oxidized glutathione were measured by an enzymatic cycling procedure. Selenium levels were also determined and compared with controls. With repeated doses, oxidant stress was more pronounced in cerebral tissue, where endosulfan shows a GABA-antagonistic activity. The possible relationship between the neurotoxicity of endosulfan and its oxidant stress-inducing effect was discussed.
