This study aimed to compare the effects of repeated restraint stress alone and the combination with clomipramine treatment on parameters of oxidative stress in cerebral cortex, striatum and hippocampus of male rats. Animals were divided into control and repeated restraint stress, and subdivided into treated or not with clomipramine. After 40 days of stress(More)
Organoselenium compounds exhibit antioxidant activity, as well as a variety of biological activities, with potential pharmacological and therapeutic applications. The aim of this study was to investigate the effect of diphenyl diselenide (PhSe)2 in reversing oxidative brain damage and mitochondrial dysfunction caused by administration of acetaminophen(More)
The acute liver failure (ALF) induced by acetaminophen (APAP) is closely related to oxidative damage and depletion of hepatic glutathione, consequently changes in cell energy metabolism and mitochondrial dysfunction have been observed after APAP overdose. Diphenyl diselenide [(PhSe)2], a simple organoselenium compound with antioxidant properties, previously(More)
Activation of the limbic-hypothalamic-pituitary-adrenal axis (LHPA) and the release of glucocorticoids are fundamental for the adaptive response and immediate survival of an organism in reaction to acute stimuli. However, high levels of glucocorticoids in the brain may produce neuronal injury and a decrease of Na(+)/K(+)-ATPase activity, with effects on(More)
Acute stroke is a major risk for morbidity and mortality in aging population. Mitochondrion has been the focus of a wide stroke-related research. This study investigated if treatment or pre-treatment with diphenyl diselenide (PhSe)2 can prevent mitochondrial damage in cerebral structures of rats induced by an ischemia and reperfusion (I/R) model. Adult male(More)
