Renoprotective effect of the Echinodorus macrophyllus in induced renal injury Efeito renoprotetor do Echinodorus macrophyllus na lesão renal induzida

Objective: Evaluating the renoprotective effect of Echinodorus macrophyllus in acute kidney injury induced by cyclophosphamide in rats. Methods: Experimental research with Wistar rats, male adults, distributed into groups, namely: Control – administration of 1.5 ml sodium chloride 0.9% intraperitoneally; Echinodorous – administration of 2g/kg of Echinodorus macrophyllus by gavage for five days; Cyclophosphamide – administration of cyclophosphamide 150mg/kg intraperitoneally; and Cyclosphosphamide + Echinodorus – administration of Echinodorus macrophyllus and cyclophosphamide. Renal function (creatinine clearance) and the oxidative metabolites (peroxides and urinary substances reactive to thiobarbituric acid, thiols in kidney tissue) were evaluated. Results: Preconditioning with Echinodorus macrophyllus elevated the creatinine clearance and reduced the levels of oxidative metabolites. Conclusion: The antioxidant action of Echinodorus macrophyllus has demonstrated renoprotective effects evidenced by the reduction of oxidative stress in acute renal injury induced by cyclophosphamide in rats.
