- Abstract
Cadmium intoxication induces lipid peroxidation and causes oxidative damage to various tissues by altering antioxidant defence system enzymes. At 24 h after treatment with a single intraperitoneal dose of cadmium chloride (5 mg kg−1), Swiss albino mice showed a significant increase in the levels of malanodialdehyde and xanthine oxidase (P<0.001), and a concomitant depletion of renal glutathione, catalase (P<0.001) and other antioxidant enzymes. CdCl2 also led to a simultaneous increase in micronuclei formation (P<0.001) and chromosomal aberrations (P<0.05) in mouse bone marrow cells. Oral pre-treatment with Pluchea lanceolata extract at doses of 100 and 200 mg kg−1 for 7 consecutive days before CdCl2 intoxication caused a significant reduction in malanodialdehyde formation and xanthine oxidase activity (P<0.001). A significant restoration of the activity of antioxidant defence system enzymes such as catalase, glutathione peroxidase (P<0.05), glutathione-S-transferase and glutathione reductase (P<0.001) was observed. A significant dose-dependent decrease in chromosomal aberrations and micronuclei formation was also observed (P<0.05). The results indicate that pre-treatment with P. lanceolata attenuates cadmium chloride induced oxidative stress and genotoxicity by altering antioxidant enzymes and reducing chromatid breaks and micronuclei formation.
