Effect of Cyclooxygenase-2 inhibition on rigidity of animal model of Parkinson's disease

Parkinson's disease (PD) is a degenerative neurodopaminergic disease in nigrostriatum pathway of animals and human, the resultant loss of nerve terminals accompanied by dopamine-glutamate and other related neurotransmitters-imbalances in this pathway are responsible for most of the movement abnormalities. Increasing evidence suggests that an inflammatory reaction accompanies the pathological processes caused by Cyclooxygenase-2 (COX-2) seen in many neurodegenerative disorders, including PD. These findings have not indicated any evidence based on the effect of selective and non selective COX-2 inhibitors on the rigidity of PD.
