The present study evaluated the effects of NO mimetics on stress-induced neurobehavioral changes and the possible involvement of ROS–RNS interactions in rats. Restraint stress (RS) suppressed both percent open arm entries and time spent in the open arms in the elevated plus maze (EPM) test. These RS-induced changes in EPM activity were attenuated by the NO mimetics, l-arginine, isosorbide dinitrate and molsidomine, in a differential manner. RS-exposed rats showed (a) increased lipid peroxidation (MDA) and (b) lowered reduced glutathione (GSH) and NO metabolites (NOx), in brain homogenates of these animals. Pretreatment with the NO mimetics also differentially influenced RS-induced changes in brain oxidative stress markers. The results suggest that NO may protect against stress-induced anxiogenic behavior and oxidative injury in the brain and highlight the significance of ROS–RNS interactions.
