neuroprotective effect of quercetin in a model of parkinson’s disease in rat: a histochemical analysis

چکیده
abstractintroduction: parkinson's disease (pd) is a neuropathological disorder involving the degeneration of dopaminergic neurons in the substantia nigra, with the subsequent loss of their terminals in the striatum. quercetin, a natural flavonoid, is a strong antioxidant and radical scavenger. therefore, its neuroprotective effect in a model of parkinson’s disease in rat was evaluated.methods: for this purpose, unilateral intrastriatal 6-hydroxydopamine (6-ohda)-lesioned rats were pretreated with quercetin (20 mg/kg i.p.) 1 hour before surgery and treated once a day for one month. nissl-stained neurons of substantia nigra pars compacta (snc) were counted. results: number of nissl-stained neurons in left side of snc of lesion group was lower relative to sham-operated group (p<0.005) and it was higher in quercetin-treated lesion group as compared to untreated lesion group (p<0.01).discussion: flavonoid quercetin administration for one month could protect the neurons of snc against 6-ohda toxicity.

Parkinson's disease (PD) is the second most common neurodegenerative disorder affecting 1 to 3% of individuals over the age of 65 years. Both retrospective and prospective epidemiological studies have consistently demonstrated an inverse association between coffee consumption and PD. This study was designed to investigate the beneficial effect of caffeine in an early model of PD. For this purpo...
