Background and Objectives: Alzheimer's disease (AD) is a neurodegenerative disease accompanied by common emotional symptoms such as anxiety and fear. The aim of this study was investigating the anti-anxiety and antioxidant effects of sumac extract and its nano-phytosome, in streptozotocin (STZ)-induced rat model of Alzheimer's disease Materials and Methods: In this experimental study, 35 male Wistar rats were divided into five groups (control, positive control, Alzheimer, and Alzheimer with (40mg/kg) doses of sumac extract and nano-phytosome -sumac). For the induction of Alzheimer model, STZ (3 mg / kg) was injected intracerebroventricularlly. 21 days after gavage, plus maze test was performed to evaluate anxiety behavior in the rats. In the end, catalase and superoxide dismutase enzyme's activity and malondialdehyde levels were measured in the cerebral cortex. Statistical analysis was performed using one-way ANOVA followed by Tukey's test. Results:The results showed that STZ increased anxiety-like behaviors (p=0.001), malondialdehyde (MDA) level (p<0.017), and decreased catalase and superoxide dismutase activity in the Alzheimer group (p<0.001); while treatment with sumac nano-phytosome reduced anxiety-like behaviors (p=0.002), increased catalase and superoxide dismutase activity and decreased MDA level in cerebral cortex (p=0.003). Conclusion:The results suggested that sumac nano-phytosome due to improving the bioavailability may reduce STZinduced anxiety-like behaviors and oxidative stress in rat model of AD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
