DIOSMIN AMELIORATES ALUMINIUM INDUCED NEUROTOXICITY IN THE HIPPOCAMPUS AND CORTEX OF MALE WISTAR RATS: A BEHAVIOURAL, BIOCHEMICAL AND MOLECULAR APPROACH Authors: Sumathi T* And Sampatkumar S
ABSTRACT
Background: Aluminium is an omnipresent metal on the Earth’s crust that has wide
application in human lives. This increases the burden of Aluminium metal exposure and
consequent deposition of it within the body. Several animal studies have shown Aluminium
deposition in the brain over a chronic period leads to neurotoxicity, and eventually trigger other
neurodegenerative diseases particularly Alzheimer’s disease. In the emerging need of new
therapeutic agents, Diosmin, a plant flavone was chosen to study the anti-neurotoxicity effects
against Aluminium neurotoxicity. The present study aimed in evaluating the effect of Diosmin
on Aluminium Chloride induced behavioural impairments, and its consequent changes in the
biochemical parameters. neurotransmitter enzyme, and neurotrophic factors were also assessed
in the study.
Methods: Briefly, Diosmin (50mg/Kg) was administered orally 1 hour prior to the induction
of Aluminium Chloride (4.8mg/Kg) through the intraperitoneal route for 28 days. At every 7th
day the behavioural paradigms were conducted. On the completion of the treatment schedule,
the animals were sacrificed and, the Hippocampus and the Cortex regions were dissected and
taken for biochemical and molecular analysis.
Results: Our results indicate a statistically significant impairment in the Spatial and Learning
Memory in the Aluminium Chloride induced rats, followed by diminished Motor Coordination.
The biochemical assessments indicated an elevation in Oxidative Stress markers with subsequent decrease in Antioxidant Status. The neurotrophic factors presented with decreased
expression. These changes were substantially attenuated by the administration of Diosmin.
Conclusion: Through our study, we conclude Diosmin as a potential flavone against
Aluminium Chloride induced neurotoxicity.
