Effects of chronic administration of ethanol, mate tea, and mate tea plus ethanol on thiobarbituric acid reactive substances (TBA-RSs) (a), on catalase (b) and glutathione peroxidase (c) activities in rat hippocampus. Data are mean ± SD for 5 independent experiments (animals) performed in duplicate. *P < 0.05; **P < 0.01; ***P < 0.001 compared to control group (Duncan multiple-range test). One catalase (CAT) unit is defined as 1 μmol of H₂O₂ consumed per minute. One glutathione peroxidase (GSH-Px) unit is defined as 1 μmol of NADPH consumed per minute.
