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 100mg/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.
开展了相关研究,以确定从灵芝(赤芝)子实体中分离出的萜类化合物对顺铂所致小鼠肾毒性的保护作用。腹腔注射顺铂(16毫克/千克体重)会导致小鼠出现显著的肾毒性。血清尿素、肌酐和碱性磷酸酶水平急剧升高,表明存在严重肾毒性。注射顺铂会使肾脏抗氧化防御系统如超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽过氧化物酶(GPx)以及还原型谷胱甘肽(GSH)浓度降低。以100毫克/千克体重的剂量口服萜类化合物可防止尿素、肌酐水平及碱性磷酸酶活性升高,还能维持肾脏抗氧化防御功能。灵芝萜类化合物还对顺铂诱导的肾组织脂质过氧化具有保护作用。结果表明,从灵芝中分离出的总萜类化合物具有显著的体内抗氧化活性,并能抵御顺铂诱导的肾毒性。这些结果提示灵芝萜类化合物在预防使用顺铂化疗期间所致肾毒性方面具有潜在的治疗用途。
