Prevention of cisplatin induced nephrotoxicity by terpenes isolated from Ganoderma lucidum occurring in Southern Parts of India

Investigations were carried out to determine the protective effect of terpenes isolated from the fruiting bodies of Ganoderma lucidum (Fr) P.Karst against nephrotoxicity caused by the cisplatin, in mice. Intraperitoneal administration of cisplatin (16 mg/kg body wt) resulted in significant nephrotoxicity in mice. Serum urea, creatinine and ALP levels were drastically elevated indicating severe nephrotoxicity . The renal antioxidant defense system such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and concentration of reduced glutathione (GSH) were depleted by cisplatin injection. The oral administration of terpenes at a dose of 100 mg/kg body weight prevented increase in urea, creatinine levels and ALP activity and also maintained the renal antioxidant defense. The Ganoderma terpenes also imparted protection against cisplatin induced renal tissue lipid peroxidation. The results indicated that the total terpenes isolated from G. lucidum possessed significant in vivo antioxidant activity and rendered protection against cisplatin induced nephrotoxicity. The results suggest the potential therapeutic use of Ganoderma terpenes to prevent nephrotoxicity caused during chemotherapy using cisplatin.
