The catecholaminergic neurotoxin 6-hydroxydopamine is used to lesion dopaminergic pathways in the experimental animal models of Parkinson's disease. The present study was aimed to evaluate the combined treatment with bioflavonoid quercetin (QN) and desferrioxamine (DFO) on 6-hydroxydopamine (6-OHDA) - induced neurotoxicity in the striatum of rats. Adult, male Sprague - Dawley rats were divided into control, sham lesion, 6-OHDA treated (300 µg, intracisternal), 6-OHDA with QN (50 mg/kg) treated, 6-OHDA with DFO (50 mg/kg) treated and 6-OHDA with QN and DFO treated groups. Striatal dopamine, protein carbonyl content (PCC), glutathione (GSH) and superoxide dismutase (SOD) were estimated. There was a significant increase (p < 0.05) in PCC and decrease in dopamine, GSH and SOD level and striatal neuronal number with 6-OHDA treatment. QN and DFO treatment significantly (p < 0.05) reduced these changes showing a significant neuronal protection. Combined treatment has a more significant effect (p < 0.05) in protecting the neurons and increasing the antioxidant enzymes in the striatum. In conclusion, an antioxidant with iron chelator treatment showed a significant neuroprotective effect against 6-hydroxydopamine (6-OHDA) by preventing dopaminergic neuronal loss and maintaining the striatal dopamine level.
