Abstract

Present study was designed to investigate modulation of experimental dementia by Pitavastatin and donepezil. Learning and memory of the swiss albino mice were studied on Morris water-maze. Celecoxib orally (p.o.)/Streptozotocin (STZ) intracerebroventricular administrations were used to induce experimental dementia. Brain acetyl cholinesterase activity was measured by EllMann's method to assess cholinergic activity of the brain. Brain thio barbituric acid reactive species (TBARS) levels and reduced glutathione (GSH) levels were measured by Ohokawa's and Beutler's method respectively, to assess total oxidative stress in brain. Total serum cholesterol level was measured by Allain's method. Celecoxib/STZ treatments produced a significant loss of learning and memory. Pitavastatin/Donepezil successfully attenuated this Celecoxib/STZ induced dementia. Higher levels of brain acetyl-cholinesterase (AChE) activity, TBARS and lower level of GSH were observed in Celecoxib/STZ treated animals, which were significantly attenuated by Donepezil. Pitavastatin also attenuated the Celecoxib/STZ induced high levels of TBARS & low levels of GSH without effecting AChE activity and total serum cholesterol levels. Celecoxib induced dementia noted in t...Continue Reading

Alzheimer's Disease: APP

Amyloid precursor protein (APP) proteolysis is critical for the development of Alzheimer's disease, a neurodegenerative disease associated with accumulation of amyloid plaques in the brain. Here is the latest research on APP and Alzheimer's disease.

Alzheimer's Disease: Amyloid Beta

Alzheimer's disease is a neurodegenerative disease associated with the accumulation of amyloid plaques in the brain; these plaques are comprised of amyloid beta deposits. Here is the latest research in this field.
