Aged garlic extract protects against doxorubicin-induced cardiotoxicity in rats

Clinical uses of doxorubicin (DOX), a highly active anticancer agent, are limited by its severe cardiotoxic side effects associated with increased oxidative stress and apoptosis. In this study we investigated whether aged garlic has protective effects against doxorubicin-induced free radical production and cardiotoxicity in male rats. A single dose of doxorubicin (25 mg/kg) caused increased both serum cardiac enzymes LDH and CPK activities and a significant increase malonyldialdehyde (MDA) in plasma. However, pretreatment of rats with aged garlic extract (250 mg/kg) for 27 days before doxorubicin therapy, reduced the activity of both enzymes, and significantly decreased of MDA production in plasma.
