“…Aluminium has been reported to accumulate in different organs in the body, thereby exacerbating cascades of chemical events that chelates other metals, leading to organ toxicity and ultimately reducing the functional austerity of the affected organ (Barkur and Bairy, 2015;Igbokwe et al, 2020b;Ward et al, 2001). Other studies have shown that aluminium toxicity induces a decrease in serum triglycerides and hepatic mitochondrial energy metabolism by causing dilatation of liver sinusoids, giving room for cholestasis, resulting to severely altered liver physiology and weight loss (Ibrahim et al, 2018;Kutlubay et al, 2013). In the present study, treatment of rats with AA+NIC following aluminium toxicity increased body weight.…”

Alzheimer's disease is the most common cause of dementia and is hallmarked by β-amyloid plaque and neurofibrillary tangles deposition in the CNS. The complex mechanism that underlies AD pathogenesis has made the development of a definitive cure futile. Exploring the possible therapeutic advantages of combining two neuromodulatory molecules with different mechanisms of neuroprotection is an interesting way of drug discovery. Ascorbic acid (AA), a potent antioxidant molecule, and nicotine (NIC), an allosteric modulator of nAChRs, have both been documented to independently proffer neuroprotection in experimental and clinical neurodegenerative cases. This study elucidated the putative therapeutic advantages of combining ascorbic acid and nicotine as a treatment regimen against the aluminium induced anxiety, corticohippocampal histopathology and perturbed neuroenergetics in rats induced with Alzheimer-like neuropathology Rats treated with 100 mg/kg aluminium chloride for 28 days presented with significantly increased stretch attend posture frequency and centre square entry. Aluminium significantly depleted the activities of G6PDH while increasing lactate levels. Corticohippocampal histomorphology of these animals showed poor histoarchitecture, increased congophilic and argentophilic densities that were coupled with increased anti-NSE immunopositivity. Animals post-treated with NIC (10mg/kg) and AA (100mg/kg) for 28 days presented with reduced anxiety level and improved corticohippocampal histomorphology. AA normalized G6PDH and lactate levels while the congophilic density was reduced by NIC. Corticohippocampal argentophilic density anti-NSE immunopositivity were also normalized by AA+NIC. The findings from this study have shown that a combination of ascorbic acid and nicotine effectively mitigated aluminium-induced corticohippocampal neuropathology and perturbed neuroenergetics.
