Abstract

To evaluate the potential protective effects of a calcium channel blocker (Verapamil) on the oxidative stress related changes with an emphasis on the antioxidant capacity of the kidneys an experimental study in rats was performed. A total of 44 rats have been included. Hyperoxaluria was induced in Group 1 by continuous administration of ethylene glycol (EG). Animals in Group 2 received Verapamil in addition to EG. Animals in Group 3 constituted the control group. In addition to the evaluation of tissue and serum levels of three scavenging enzymes, NO, MDA and T-AOC; the presence and degree of crystal formation in renal parenchyma were evaluated in all animals after 7 and 28 days. Our data demonstrated that in addition to the lower level of all three scavenging enzymes (SOD, CAT and GSH) particularly during late phase evaluation (4 weeks); the total antioxidant capacity (T-AOC) of these kidneys were also higher when compared with the animals receiving EG only. Tissue and serum levels of both NO and MDA indicated the preventive effect of Verapamil on the oxidative stress induced changes. Very limited or no crystallization in the kidneys treated with verapamil during early and late phase examination was observed when compared with considerable crystal formation in Group 2 animals. Verapamil treatment may preserve the oxidant capacity of the kidneys and subsequently limit the crystal deposition induced by hyperoxaluria. Verapamil could therefore be considered in the management of kidney stone formation particularly in cases with recurrent kidney stone disease.
