Anticataleptic activity of Zamzam water in chlorpromazine induced animal model of Parkinson disease.

Parkinsonism is characterized by rest tremor, inflexibility, balance debilitation, slow motion and dementia. It is known to be caused by the deficiency of dopaminergic neurons in nigrostriatal pathway. Different studies propose that oxidative burden may be included in the apoptotic process in parkisnons disease. Zamzam water being alkaline in composition may diminish the oxidative stress and hence relieve the symptoms. Therefore, the purpose of this study was to explore the neuroprotective effect of zamzam water in chlorpromazine induced animal model of Parkinsonism. Results revealed that zamzam water did not show significant anticataleptic effect after 21 days as compared to chlorpromazine treated group. However, after 30 days of giving zamzam water showed highly significant decrease (p<0.001) in cataleptic score as compared to chlorpromazine treated group that is negative control. After 30 days of dosing, cataleptic scores by zamzam water were closer to standard drug but standard drug (levodopa/carbidopa) still showed better results than zamzam water. Results from histopathological study of rat's brain also revealed regenerative changes by zamzam treated water when compared with negative control. This regenerative change after zamzam water treatment might play a positive role in future if administered continuously. These results also suggest that zamzam water can be used in combination with standard drug to produce synergistic effect in the management of parkinsons disease.
