Abstract
INTRODUCTION: Most of the pharmaceutical effects of alcohol are due to its accumulation in the brain. Ksheerabala (101) an Ayurvedic formulation mainly used against central nervous system disorders. AIM: To determine the antioxidant and neuroprotective effect of Ksheerabala (101) on alcohol-induced oxidative stress in rats. MATERIALS AND METHODS: Male Albino rats of Sprague-Dawley strain were grouped into four; control, alcohol (4 g/kg), Ksheerabala (15 μL/1 ml milk/100 g) and Ksheerabala (15 μL/1 ml milk/100 g) + alcohol (4 g/kg). After the experimental period (90 days), the animals were sacrificed and the effect of Ksheerabala (101) was studied on oxidative stress, inflammatory markers, and induction of transcription factor in brain. Results were statistically analyzed by one-way ANOVA. RESULTS: The activities of antioxidant enzymes and reduced glutathione which were decreased in alcohol-treated rats, increased significantly in co-administered groups. The lipid peroxidation products and protein carbonyls which were increased significantly in alcohol-treated rats decreased significantly in co-administered groups. The expression of gamma-glutamyl cysteine synthase decreased significantly in alcohol-treated rats and increased significantly in co-administered groups. The transcription factor nuclear factor-κB (NFκB) which was up-regulated in alcohol-treated rats was down-regulated in co-administered rats. The histopathology reinforced these results. CONCLUSION: Ksheerabala (101) attenuates alcohol-induced oxidative stress and down-regulates the expression of NFκB in rat brain.
