Geraniol alleviates cyclophosphamide-induced cardiotoxicity in mice

Abstract

Objective: To explore the effect of geraniol on cyclophosphamide- induced cardiotoxicity. Methods: Mice were divided into five groups: the control group, the cyclophosphamide group (200 mg/kg cyclophosphamide, i.p. on day 7), the group treated with geraniol 100 and 200 mg/kg from day 1 to day 14, along with a single dose of cyclophosphamide on day 7, and the geraniol alone group (200 mg/kg geraniol from day 1 to day 14). At the end of the study, animals were sacrificed, and blood and heart were collected and analyzed for biochemical, histopathological, and immunohistochemical changes. Results: Treatment with 200 mg/kg geraniol significantly reduced the levels of cardiac injury markers, malondialdehyde, and inflammatory and apoptotic markers, while increasing antioxidant activities in mice with cyclophosphamide-induced cardiotoxicity. Moreover, it remarkably alleviated histopathological aberrations in cardiac tissue. Conclusions: Geraniol attenuates cyclophosphamide-induced cardiotoxicity via antioxidant, anti-inflammatory, and antiapoptotic effects.
