Studies have consistently reported the participation of oxidative stress in bipolar disorder (BD). Evidence indicates that epigenetic regulations have been implicated in the pathophysiology of mood disorders. Considering these evidences, the present study aimed to investigate the effects of sodium butyrate (SB), a histone deacetylase (HDAC)inhibitor, on manic -like behavior and oxidative stress parameters (TSARS and protein carbonyl content and SOD and CAT activities) in frontal cortex and hippocampus of rats subjected to the animal model of mania induced by intracerebroventricular (ICV) ouabain administration. The results showed that SB reversed ouabain-induced hyperactivity, which represents a manic -like behavior in rats. In addition, the ouabain ICV administration induced oxidative damage to lipid and protein and alters antioxidant enzymes activity in all brain structures analyzed. The treatment with SB was able to reversesboth behavioral and oxidative stress parameters alteration induced by ouabain.In conclusion, we suggest that SB can be considered a potential new mood stabilizer by acts on manic -like behavior and regulatesthe antioxidant enzyme activities, protecting the brain against oxidative damage.
