Effects of different doses of vitamin C on lipid peroxidation levels in hippocampus in redox balance and in oxidative stress. The lipid peroxidation levels mainly increased in the group exposed to ozone (O3) and in the group that receive 50 mg/kg of vitamin C (C50). At any doses of vitamin C greater than 50 mg/kg the effect on lipid peroxidation levels was not as evident as in the C50 and O3 groups. In the groups that receive vitamin C and were exposed to ozone, vitamin C exerted an antioxidant effect (O3 + C50 and O3 + C100), except in the O3 + C200 group.
