The control group received saline. Brain malondialdehyde (MDA), nitric oxide (NO), reduced glutathione (GSH), acetylcholinesterase (AChE), amyloid Aβ peptide, and interleukin-6 (IL-6) concentrations and paraoxonase-1 (PON-1) activity were determined and brain histology was done. Behavioral and neurological testing included Morris water maze (WMZ), Y maze, and wire hanging. Results: Compared with saline controls, AlCl3 significantly increased brain MDA and NO along with decreased GSH and PON-1 activity. It also increased AChE, IL-6, and amyloid Aβ concentrations. AlCl3 impaired motor strength and memory performance and caused brain neurodegeneration. B. spectabilis decoction given at 50 or 100 mg/kg protected against the biochemical and histopathological alterations evoked by AlCl3 by alleviating the increase in MDA and NO, and decrease in GSH and PON-1 activity.  B. spectabilis decoction showed no significant effect on AChE but markedly decreased IL-6 and amyloid Aβ in the brain of AlCl3-treated rats. It also restored memory performance and motor strength, and protected against AlCl3-induced neurodegeneration.Conclusion: These results suggest that B. spectabilis flower decoction might prove of value in the treatment of Alzheimer’s disease.}, keywords = {Aluminum chloride,Amyloid Aβ,Bougainvillea spectabilis- flowers,Interleukin-6,Neurodegeneration,Oxidative stress,Paraoxonase}, url = {https://ijbms.mums.ac.ir/article_18852.html}, eprint = {https://ijbms.mums.ac.ir/article_18852_552d25586838b6ee38e61be59e40a5b9.pdf} }
