Chronic restraint stress induced neurobehavioral alterations and histological changes in rat

Several lines of research on human and rodent subjects have demonstrated that stress results in multiple negative outcomes, including increased incidence of psychopathologies. Restraint stress in rats is known to adversely affect the physiological, psychological and reproductive axis in rats. Male rats were subjected to restraint stress for 3 hours consecutively for 14 days. The behavioral studies include Elevated Place Maze, Open Field and Morris Water Maze tests. Our results show that chronic restraint stress involved a development of anxiety in EPM, reduced motor activity in OF, impaired memory spatial in MWM tests, and induced change in testicular function, as reflected by significant decrease in plasma level of testosterone, correlate well with the damages in testis. The Results of the present study confirm that chronic restraint stress induced cognitive dysfunction, enhance anxiety like behavior and induced testicular damage in male rats Wistar.
