GSR and status epilepticus: Therefore, the objectives of the present study were to determine the effects of LEV on the activities of four antioxidant enzymes (SOD, CAT, GPx, glutathione reductase (GR) and glutathione (GSH) and on the levels of four oxidant stress markers (H2O2, carbonylated proteins, malondialdehyde (MDA) and 8-hydroxy-2-deoxyguanosine (8-OHdG)) in the hippocampus of a TLE animal model at 5.7 months after status epilepticus (SE).
