ABSTRACT
OBJECTIVE: This study aimed to investigate the impact of tert-butylhydroquinone (TBHQ), chitosan, and their combination on memory and neurobiochemical parameters in a rat model. The primary objectives were to assess the cognitive effects of TBHQ, explore the cognitive-enhancing properties of chitosan, and evaluate the combined effects of these substances. MATERIALS AND METHODS: A rat model was employed for behavioral tests, biochemical analyses, and histological examinations. Rats were exposed to TBHQ, chitosan, or a combination of both, and cognitive function was assessed through behavioral tests. Biochemical analyses focused on neurobiochemical parameters associated with memory and oxidative stress. Histological examinations were conducted to observe any structural changes in the brain. RESULTS: TBHQ exposure was associated with memory impairments and increased oxidative stress, indicating potential neurotoxic effects. Chitosan supplementation demonstrated cognitive-enhancing effects and showed promise in mitigating the memory impairments and oxidative stress induced by TBHQ. The combination of chitosan and TBHQ presented a potential protective effect on neurological health. CONCLUSIONS: Chitosan supplementation alongside TBHQ may mitigate memory impairments and oxidative stress associated with TBHQ exposure in a rat model. The study provides valuable insights into the cognitive effects of TBHQ and the neuroprotective potential of chitosan, highlighting the need for further research to elucidate molecular pathways and clinical implications. These findings contribute to understanding chitosan's role in safeguarding neurological health in conditions where TBHQ exposure is a concern, warranting further investigations for translational applications in human health.
