Proanthocyanidin protects against cisplatin-induced nephrotoxicity.

Cisplatin (CP) [cis-diamminedichloroplatinum (II)] is one of the most widely therapeutic agents used for treating many types of cancer. At effective doses, CP causes nephrotoxicity which has been attributed to the induction of reactive oxygen species (ROS). In the present investigation proanthocyanidin (PA) was studied to demonstrate its therapeutic efficacy against CP-induced nephrotoxicity in mice. Cp treatment caused significant elevation of urea, creatinine and IL-6. In addition, CP enhanced malondialdehyde (MDA) levels and lowered the glutathione (GSH) content in kidney. On the other hand, superoxide dismutase (SOD) activity was decreased. These alterations were reversed by PA in a dose-dependent manner. These findings suggested a beneficial role of PA in attenuating CP-induced oxidative renal toxicity. Copyright (c) 2009 John Wiley & Sons, Ltd.
