Role of Garlic Extract and Silymarin Compared to Dimercaptosuccinic Acid (DMSA) in Treatment of Lead Induced Nephropathy in Adult Male Albino Rats

This study was conducted to compare the curative role of garlic combined with silymarin versus dimercaptosuccinic acid (DMSA) in decreasing lead induced nephrotoxicity in adult male albino rats. The period of lead intoxication extended for 3 months followed by either 1 month treatment with garlic and silymarin or 5 days treatment with DMSA. Lead poisoning caused non-significant difference in kidney function tests (BUN and serum creatinine) while, it caused significant elevation in kidney lead level, significant decrease in renal antioxidant enzyme glutathione peroxidase and significant elevation in kidney malondialdehyde. Histologically, lead induced disorganization and shrinkage of glomeruli with sloughing and vaculation of epithelium, widening of Bowman's space and inflammatory infiltration in renal medulla. Treatment by garlic extract combined with silymarin as well as treatment with DMSA resulted in significant improvement in the affected parameters. Also, both methods of treatment resulted in improvement of the histopathological changes. It can be concluded that garlic extract combined to silymarin is comparable to DMSA in amelioration of lead induced nephrotoxicity.
