Abstract

The present study evaluated the effects of AR-A014418 on behavioral and oxidative stress parameters of rats submitted to the animal model of mania induced by ouabain (OUA). Wistar rats were submitted to stereotaxic surgery and received a single intracerebroventricular (ICV) injection of artificial cerebrospinal fluid (aCSF), OUA, or AR-A014418. After 7 days, the animals were submitted to open-field test. After behavioral analysis, the brains were dissected in frontal cortex and hippocampus to the evaluation of oxidative stress. The OUA induced manic-like behavior in rats, which was reversed by AR-A014418 treatment. The ICV administration of OUA increases the levels of superoxide in submitochondrial particles, lipid hydroperoxide (LPH), 4-hydroxynonenal (4-HNE), 8-isoprostane, protein carbonyl, 3-nitrotyrosine, and activity of superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione reductase (GR) in both structures evaluated. In general, the treatment with AR-A014418 reversed these effects of OUA on the submitochondrial particles, LPH, 4-HNE, 8-isoprostane, protein carbonyl, 3-nitrotyrosine levels, and SOD activity. Furthermore, the injection of OUA decreased the catalase activity, and AR-A014418 promoted an in...Continue Reading
