Doxorubicin (DOX) is an anti-neoplastic therapy, but its use limited by deleterious toxic effects including nephrotoxicity and cardiotoxicity. This work aimed at assessing the potential protective effect of Ceratonia siliqua methanol extract (CME) on DOX-induced in 5 groups Wistar rats. Nephrotoxicity was induced experimentally intraperitoneal (IP) injection DOX (15 mg/kg). increased serum creatinine, urea, sodium, potassium levels. It elevated MDA levels renal tissue decreased concentration...
