ABSTRACT
Objective: The present study was undertaken to evaluate the effects of naringin on immobilization stress-induced biochemical-behavioral changes and mitochondrial dysfunction in mice. Methods: Mice were randomized and grouped based on body weights. Respective drug treatments were given for 14 d, and on the 15th day all the animals were subjected to a 6-hour immobilization stress; then all the animals were subjected to various behavioral paradigms and were sacrificed. Various biochemical parameters and mitochondrial functions were analyzed using brain homogenate. Results: The 6-hour acute immobilization stress significantly altered the behavioral (anxiety and memory) and biochemical parameters coupled with mitochondrial dysfunction in mice. Fourteen days pretreatment with naringin (50 and 100 mg/kg, per oral) significantly inhibited the behavioral and biochemical alterations and mitochondrial dysfunction caused by acute immobilization stress (P
