|Abstract:||Stress is an aversive stimulus which disturbs physiological homeostasis and is reflected on a variety of biological systems. The present study was designed to investigate the nitric oxide mechanism in neuroprotective effect of trazodone and citalopram against acute immobilization-induced behavioral and biochemical alteration in mice. Mice were immobilized for a 6 h. Acute immobilization stress caused anxiety, hyperalgesia, impaired locomotor activity and oxidative damage. Pre-treatment with trazodone and citalopram significantly reversed immobilized stress-induced behavioral and biochemical alterations. L-arginine, pretreatment with trazodone or citalopram significantly reversed their protective effects. However, L-NAME or methylene blue pretreatment with trazodone or citalopram significantly potentiated their protective effects alone. Results suggest the involvement of nitric oxide pathways in the protective effect of trazodone and citalopram against immobilization stress induced behavioral and biochemical alterations|
