SOD1 and epilepsy: In a few studies it has been shown that LEV possesses antioxidant properties, increasing antioxidant markers, such as GSH, SOD, and GPx activities, and decreasing oxidant markers, such as TBARS, nitrite/nitrate, 8-OHdG, and 8-isoprostanes levels, in experimental models of epilepsy [20,27,28,29,71,72].
