In this paper, the effect of nicotine on the oxidative changes produced by 3-nitropropionic acid (20 mg/kg i.p./day for 4 days) in striatal and cortical synaptosomes of Wistar rats was studied. The effects of 3-nitropropionic acid were evaluated as changes in the quantity of protein carbonyl groups, lipid peroxidation products, superoxide distumase activity and reduced succinate dehydrogenase activity. All changes were prevented by the pre-injection of nicotine (1.5 mg/kg i.p./day), beginning 4 days before and continuing for 4 days after the first injection of 3-nitropropionic acid. These findings indicate that: (i) 3-nitropropionic acid induces a state of oxidative stress in cortical and striatal synaptosomes and (ii) nicotine prevents oxidative stress induced by 3-nitropropinonic acid. In conclusion, the results show the ability of nicotine to modify neural response to 3-nitropropionic acid with the protective mechanism likely involving the antioxidative processes of nicotine.
