Effects of different doses of vitamin C on memory in redox balance and in oxidative stress. The retention latency was significantly decreased in the short term memory (STM) and in the long term memory (LTM) in the group that receive 0.7 ppm of ozone (O3) and in the group that receive 50 mg/kg of vitamin C (C50). Meanwhile, at any other doses greater than 50 mg/kg the retention latency were similar to the one of the control group. When any doses of vitamin C were added to the group exposed to ozone, the retention latency in STM and LTM was similar to that of the control group.
