Abstract
Objective(s) Portulaca oleracea L. is a herbaceous weed from portulacaceae family. It can be found in many parts of the world. Modern pharmacological studies have demonstrated that P. oleracea have antioxidant effects. The protective effect of aqueous and ethanolic extract of P. oleracea against cisplatin-induced renal toxicity was studied in rats. Materials and Methods Single intraperitoneal injection of 4 mg/kg cisplatin was administrated to rats. After 5 days, blood urea nitrogen (BUN) and serum creatinine (Scr) concentration were determined. Effect of aqueous and ethanolic extracts, before and after cisplatin injection on BUN and Scr, as well as morphological renal damage, was evaluated. Results It was indicated that treatment with aqueous and ethanolic extracts of P. oleracea in the highest dose (0.8 and 2 g/ kg), 6 and 12 hr before cisplatin injection reduced BUN and Scr. Tubular necrotic damage was not observed either. Conclusion Results suggest that P. oleracea extract may protect against cisplatin-induced renal toxicity and might serve as a novel combination agent with cisplan to limit renal injury.
