Protective effect of Withania somnifera Dunal on the behavioral and biochemical alterations in sleep-disturbed mice (Grid over water suspended method).
Sleep disruption involves extensive changes in physiological function, including EEG, motor, metabolic, autonomic processes physiological homeostasis and psychological balance that are necessary for physical health. Benzodiazepines are the most widely used drugs for the sleep related problems in spite of their limitations and side effects. Objective of the study was to investigate the protective effect of W. somnifera on the behavioral and biochemical alterations in sleep disturbed mice. Pretreatment with W. somnifera root extract (100. 200 mg/kg) and diazepam (0.5 mg/kg) significantly protected reduction in body weight, improved the reduced locomotor activity and anxiety levels in animals. Biochemical studies also revealed that W. somnifera (100 and 200 mg/kg) and diazepam (0.5 mg/kg) pretreatment for five days decreased significantly lipid peroxidation, nitrites levels and improved catalase, and reduced glutathione levels. Co-administration of W. somnifera (100 mg/kg) with diazepam (0.5 mg/kg) improved significantly all the biochemical parameters as compared to their effect per se. Preliminary results suggest that Withania root extract can be used in the management sleep loss and associated oxidative stress.
