Neuroprotective impact of glycitin on memory impairment in a pentylenetetrazol-induced chronic epileptic rat model: insights into hippocampal histology, oxidative stress, and inflammation

Epilepsy, characterized by recurrent seizures, often accompanies neurocognitive impairments and is associated with increased oxidative stress and inflammation. This study investigates the possible neuroprotective properties of glycitin, a soy isoflavone, on memory impairment, its impact on oxidative stress responses, and inflammatory gene expression in a chronic epileptic rat model induced by pentylenetetrazol (PTZ). Glycitin was administered at varying doses to evaluate its potential neuroprotective impact on memory, oxidative stress, and inflammation in this model. Behavioural assessments, memory retention and recall capabilities, histopathological examinations, measurements of oxidative stress biomarkers, and molecular assessments were employed for comprehensive evaluation. The results demonstrated that glycitin significantly improved memory impairment and reduced oxidative stress in epileptic rats. Additionally, glycitin treatment decreased the expression of tumor necrosis factor-α (TNF-α) and nuclear factor kappa B (NF-κB), indicating its potential to modulate the inflammatory response associated with epilepsy. These observations underscore the potential of glycitin as a therapeutic candidate for mitigating memory impairments linked to chronic epilepsy due to its antioxidant and anti-inflammatory properties, offering insights into novel avenues for the development of targeted interventions aimed at preserving cognitive function and ameliorating oxidative damage and inflammation in epileptic conditions.
