Abstract

Introduction/Aim

The study examines how chronic resveratrol administration affects behavioral and neurochemical changes caused by Lorazepam (LZP), a classical anti-anxiety medicine associated with neurodegenerative and neurological problems.

Method

Forty male rats were placed into four groups: a control group receiving 1% Tween 80, the LZP group receiving 2 mg/kg/day, the Resveratrol group receiving 50 mg/kg/day, and the LZP plus resveratrol group receiving the same doses of LZP and Resveratrol. Oral therapy was given daily for 6 weeks. The animals were euthanized after open field and Y maze behavioral tests. In specific brain regions, neurochemical analyses were performed on GABA, glutamic acid, monoamines (norepinephrine, dopamine, and serotonin) and their metabolites, DNA fragmentation (8-hydroxy-2–deoxyguanosine or 8-HdG), brain-derived neurotrophic factor (BDNF), and Ca-ATPase.

Results

Resveratrol therapy improved GABA, glutamic acid, monoamines, and their metabolites in the cerebral cortex, hippocampus, and striatum. Additionally, it reduced DNA fragmentation (8-HdG) and counteracted LZP-induced Ca-ATPase downregulation at a significant level ( 0.05). Resveratrol also reversed LZP-induced behavioral changes in the Y maze and open field tests.

Conclusion

Resveratrol has anxiolytic-like actions like benzodiazepines and neuroprotective capabilities against LZP-induced adverse effects.
