- W2509313097 abstract "Event Abstract Back to Event Evaluation of histomorphometric and neurochemical changes in the aluminium treated hippocampus following treatment with Huperzine A Nilesh K. Mitra1* 1 Taylor's University, Department of Anatomy, School of Medicine, Malaysia Aluminium (Al) is used in cooking utensils, as adjuvant in vaccines and is found in drinking water as a flocculent. The neurotoxic symptoms of aluminium exposure include speech disturbances, tremors, psychosis, partial memory loss and cognitive deficits, some of which mimic neurodegenerative diseases like Alzheimer’s and Parkinson’s Diseases. Huperzine A, a lycopodium alkaloid and acetylcholinesterase (AChE) inhibitor has been used as a neuroprotective agent in traditional Chinese medicine. The objective of this study was to determine the effect of Huperzine A on brain AChE and MAO activity and histomorphometry of hippocampal neurons in albino mice pre-treated with Aluminium Chloride. Female ICR mice (22 weeks, n=6) were treated intraperitoneally with Al (30mg/kg) for 14 days followed by post-treatment with saline, Huperzine A (0.5mg/kg), Huperzine A (0.2mg/kg) and Huperzine A (0.1mg/kg)(Al-Hup 0.1) for further 14 days. A control group was treated with saline. AChE and MAO levels were estimated using spectroflurometric methods from blood and brain samples. Thionin stained coronal serial sections (8 µ) of brain samples were used to estimate neuronal density of neurons of hippocampus using NIS Elements Software. Al treated mice showed decrease in serum AChE and increase in brain AChE. Al-Hup 0.1 group showed significant decrease in brain AChE activity. Brain MAO activity was increased by Al treatment, whereas, Huperzine A post–treatment decreased MAO activity significantly. The neuronal density in CA1, CA2 and CA3 areas of hippocampus following Al treatment showed significant reduction (p<0.001). All Huperzine A post-treatment groups showed increase in neuronal density significantly (p<0.001) in the 3 areas compared to Al-saline group. It can be concluded that although Al has a biphasic effect on serum and brain AChE, it has a persistent toxic effect on neurons of hippocampal formation. Huperzine A has neuro-protective effect on Al induced neurotoxicity in hippocampus.
