Ameliorative Effect of Grape Seed Oil on Aluminium Chloride Induced Neurotoxicity on Rats

Aims: Neurodegenerative disorder is characterized by progressive loss of structure and function of neurons. Exposure to aluminum causes neurodegenerative disorders like dementia, and Alzheimer's disease (AD). The present study was designed to examine the ameliorative effect of grape seed oil extraction aluminium chloride induced neurotoxicity in Wistar rats.

Methodology: Wistar rats were administered with aluminium chloride (175 mg/kg. p.o.) for 28 days to generate neurotoxicity model. Attenuation effect of grape seed oil against aluminium chloride toxicity by oral administration adjunctly from day 18. Behavioral and locomotor activity was determined using passive avoidance test, open field test, actophotometer and rota rod test. Biochemical parameter such as acetylcholinesterase (AChE) activity andsuperoxide dismutase (SOD), catalase (CAT) and glutathione reductase (GR) activity were assessed in brain samplesand histology of brain tissue were assessed on the final day of the experiment.

Results: Aluminium chloride treatment significantly decreases cognitive function and open field test with a significance decrease in the acetylcholinesterase and antioxidant (SOD, CAT, GR) activity level. Also, the histopathological examination shows significance decrease in the neuronal cell density in hippocampal region. Grape seed oil treated with aluminum chloride neurotoxic groups alleviates all the toxicity induced by the aluminum chloride. Histopathological studies in the hippocampus and cortex of the rat brain also supported that the grape seed oil markedly reduced the toxicity of aluminium chloride.

Conclusion: Supplementation of grape seed oilexhibited with beneficial and neuroprotective role on aluminium chloride induced neurotoxicity in Wistar rat modelby improving the cognitive memory and antioxidant enzyme level.
