PROTECTIVE EFFECTS OF CURCUMA LONGA IN A ROTENONE-INDUCED RAT MODEL OF PARKINSON'S DISEASE: ELECTROPHYSIOLOGICAL AND...

Area of Science:

• Neuroscience
• Pharmacology
• Natural Product Research

Background:

• Parkinson's disease (PD) involves progressive dopaminergic neurodegeneration, leading to motor deficits.
• Current neuroprotective therapies for PD are limited.
• Curcuma longa (turmeric) possesses antioxidant properties with potential neuroprotective benefits.

Purpose of the Study:

• To investigate the neuroprotective potential of orally administered turmeric extract in a rotenone-induced rat model of Parkinson's disease.

Main Methods:

• A rotenone-induced rat model was used to mimic Parkinson's disease pathology.
• Rats received rotenone for 21 days, followed by concurrent turmeric extract treatment.
• Neuroprotection was assessed via in vivo electrophysiology and the Cylinder test for motor function.

Main Results:

• Turmeric extract administration significantly prevented rotenone-induced neurodegenerative changes.
• Motor impairments and forelimb use asymmetry were mitigated by turmeric treatment.
• Neuronal integrity and function were preserved in rats treated with turmeric extract.

Conclusions:

• Turmeric extract demonstrates significant neuroprotective effects against rotenone-induced neurotoxicity.
• These findings support the potential of turmeric as a therapeutic agent for Parkinson's disease.
• Further research is needed to explore molecular mechanisms and optimize dosage for PD treatment.
