The effect of modafinil on passive avoidance memory, brain level of BDNF and oxidative stress markers in sepsis survivor rats.

Male Wistar rats (250-350g) were submitted to CLP, or sham as control, and divided into the sham + water, sham + MD (300 mg/kg), CLP + water, and CLP + MD (300 mg/kg) groups. Ten days after the administration of MD and CLP, the rats were submitted to a memory test by passive avoidance apparatus being sacrificed. The nitrite and nitrate (N/N) concentration, myeloperoxidase (MPO) and catalase (CAT) activity, lipid and protein oxidative damage, and brain-derived neurotrophic factor (BDNF) levels were measured in the prefrontal cortex and hippocampus.
