Abstract

Cyclophosphamide (CP), an alkylating agent widely used in cancer chemotherapy causes cardiac membrane damage. Lupeol, a pentacyclic triterpene, isolated from Crataeva nurvala stem bark and its ester, lupeol linoleate possess a wide range of medicinal properties. The effect of lupeol and its ester was evaluated in CP induced alterations in cardiac electrolytes in rats. Male albino rats of Wistar strain were categorized into 6 groups. Group I served as control. Rats in groups II, V and VI were injected intraperitoneally with a single dose of CP (200 mg/kg body weight) dissolved in saline. CP treated groups V and VI received lupeol and lupeol linoleate (50 mg/kg body weight) respectively, dissolved in olive oil for 10 days by oral gavage. At the end of the experimental period, urinary risk factors, activities of ATPases and electrolytes were measured using standard procedures. CP administered rats showed a significant decrease (P < 0.001) in the activities of ATPases. It was associated with significant alterations (P < 0.001) of electrolytes both in serum and cardiac tissue. The levels of urea, uric acid and creatinine were also significantly (P < 0.001) altered in the serum and urine. Lupeol and its ester showed reversal of the above alterations induced by CP. These findings demonstrate that the supplementation with lupeol and its ester could preserve membrane permeability, highlighting their protective effect against CP induced cardiotoxicity.
