CO-ADMINISTRATION OF RESVERATROL RESCUED LEAD-INDUCED TOXICITY IN DROSOPHILA MELANOGASTER

Lead toxicity poses a significant environmental concern linked to diverse health issues, including cognitive impairments, behavioral abnormalities, reproductive defects, and oxidative stress at the cellular level. This study explores the potential mitigating effects of resveratrol on lead-induced toxicity in Drosophila melanogaster. Adult D. melanogaster of the Harwich strain, aged three days, were orally exposed to lead (60 mg/L), Succimer (10 mg/kg), and varying doses of resveratrol (50, 100, and 150 mg/kg). The investigation encompassed the assessment of selected biological parameters, biochemical markers (ALP, AST, TB, CB, Na, Ca, Ur, Cr), oxidative stress indicators (MDA), and antioxidant enzymes (SOD and CAT). Resveratrol exhibited a dose-dependent enhancement of egg-laying, eclosion rate, filial generation output, locomotor activity, and life span in D. melanogaster, significantly to 150 mg/kg of diet. Most of the investigated biochemical parameters showed significant rescue in lead-exposed fruit flies when co-treated with resveratrol (p < 0.05). However, oxidative stress, as indicated by MDA levels, remained unaffected by resveratrol in this study. The findings suggest that resveratrol effectively protects against lead toxicity in Drosophila melanogaster and may hold therapeutic potential as an agent for managing lead poisoning in humans.
