Assessment of ibuprofen as a neuroprotective agent in chronic cerebral hypoperfusion-induced neurodegeneration in rats.
Aging related reduction in cerebral blood flow (CBF) has been linked with neurodegenerative disorders including Alzheimer's diseases and dementia. Experimentally, a condition of chronic cerebral hypoperfusion due to reduced can be induced by permanent bilateral occlusion of common carotid arter...

Aging related reduction in cerebral blood flow (CBF) has been linked with neurodegenerative disorders including Alzheimer's diseases and dementia. Experimentally, a condition of chronic cerebral hypoperfusion due to reduced can be induced by permanent bilateral occlusion of common carotid arteries (2-vessel occlusion, 2VO) in rats. Since neuroinflammation, leading to neuronal apoptosis and death, is one of the mechanisms which is thought to play a significant role in chronic degenerative neurological disorders, the present study was planned to assess the neuroprotective role of ibuprofen in chronic cerebral hypoperfusion-induced neurodegeneration. Fifteen rats were equally divided into 3 groups. Group A - sham control, Group B - 2VO, and Group C - 2VO-I (treated daily with 50mg/kg orally ibuprofen following 2VO). After 8 weeks, all the rats were euthanized and the hippocampi were isolated. Viable neuronal cell count in the hippocampal CA1 region, hippocampal COX-2 mRNA expression and prostaglandin E2 (PGE-2) levels were estimated. There was a significant difference in neuronal cell death, increasing in COX-2 mRNA expression and PGE-2 levels in 2VO group compared to Sham control group.
