HYPERICUM PERFORATUM IMPROVE MEMORY AND LEARNING IN ALZHEIMER'S MODEL: (EXPERIMENTAL STUDY IN MICE)
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2016, Vol 8, Issue 8
Abstract
Objective: The aim of this study, we based on protective and antioxidant efficiency of Hypericum perforatum that shows a wide range of beneficial effect in vitro and in vivo.Methods: The in vitro antioxidant activity of the extract was assessed by using several antioxidant tests. The cytotoxic activity of Hypericum perforatum was also determined by using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide viability assay on ordinary used cell lines. In vivo experiments in Swiss mice were determined by performing behavioral, memory tests and histological study. According to tests results, H. perforatum may be relevant to the treatment of cognitive disorders.Results: The results of chemical analysis showed a hight level of hyperforin and quercitin that had an important antioxidant activity proved in vitro with the 2, 2-diphenyl-1-picrylhydrazyl, Anti-lactoperoxidase and superoxide dismutases; this antioxidant activity was confirmed in vivo after the non-toxic results by means of improvement in behavioral and memory than the reducing shrunken in pyramidal cells of mice brains.Conclusion: The present study suggests that Hypericum perforatum modulate the oxidative stress and be involved in the protective effect against oxidative damage and neurodegenerative diseases in mice.
