Cardio- Nephroprotective Effects of Guava and Olive Leaf Extracts on Doxorubicin-Induced Toxicity in Rats Abstract Objective: Doxorubicin (DOX) is an anticancer drug that is known to increase oxidative stress in several organs. Our objective was to evaluate the possible cardioprotective and nephroprotective effects of guava leaf extract (GLE) and olive leaf extract (OLE) on DOX-induced toxicity in rats. Methods: Forty adult male albino rats were randomly divided into 4 groups of 10 rats each, as
