The effect of rutin on cisplatin-induced oxidative cardiac damage in rats

Objective: Cisplatin is an anticancer drug used for treating childhood solid tumors. Symptoms related to cisplatin-induced cardiovascular adverse effects may be mild or severe. Rutin (vitamin P1) has many properties, including as antioxidant, anticancer, antidiabetic, antimicrobial, antiulcer, and tissue renewal properties. Therefore, we aimed to biochemically, histopathologically, and immunohistochemically demonstrate the effect of rutin on cisplatin-induced cardiotoxicity in rats. Methods: The rats included in our study were divided into four groups: Healthy group (HE), 5-mg/kg cisplatin group (CP), 50 mg/kg rutin+5-mg/kg cisplatin (CR-50), 100-mg/kg rutin+5-mg/kg cisplatin (CR-100) group. Results: CP group administered cisplatin had significantly increased blood, serum, and cardiac tissue malondialdehyde (MDA), interleukin 1 beta (IL-1β), tumor necrosis factor alpha (TNF-α), troponin I, creatine kinase (CK), and CK-MB levels compared to the HE group, whereas there was a significant decrease in the total glutathione (tGSH) levels. Rutin was observed to prevent the increase in MDA, IL-1β, TNF-α, troponin I, CK, and CK-MB levels as well as prevent the decrease in tGSH levels more significantly when administered at a 100-mg/kg dose than at a 50-mg/kg dose. Histopathologically, cardiac necrosis, dilated/congested blood vessels, hemorrhage, polymorphonuclear leukocyte, edema, and cells with pyknotic nuclei were observed in the CP group. Rutin was shown to prevent cisplatin-induced cardiac damage more effectively when used at a100-mg/kg dose than at a 50-mg/kg dose. Conclusion: These results suggest that rutin is useful for preventing cisplatin-related cardiovascular damage. Keywords:
