Pretreatment of ethyl acetate extract of Phellinus rimosus (Berk) Pilat protected cisplatin induced nephrotoxicity in mice. Single dose of the extract (25 and 50 mg/kg body weight) decreased cisplatin induced serum creatinine and urea levels. The cisplatin depleted renal antioxidant defence system, such as activity of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) and concentration of reduced glutathione (GSH), were restored by the treatment of the extract. The enhanced renal antioxidant defence system prevented cisplatin induced tissue lipid peroxidation. The experimental results suggest that ethyl acetate extract of P. rimosus protected cisplatin induced nephrotoxicity, possibly by enhancing renal antioxidant status. The extract did not interfere with the antitumor efficacy of cisplatin.
桑黄(Phellinus rimosus (Berk) Pilat)乙酸乙酯提取物预处理可保护顺铂诱导的小鼠肾毒性。单剂量提取物(25和50毫克/千克体重)可降低顺铂诱导的血清肌酐和尿素水平。顺铂会消耗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)的活性以及还原型谷胱甘肽(GSH)的浓度,而提取物处理可使其恢复。增强的肾脏抗氧化防御系统可防止顺铂诱导的组织脂质过氧化。实验结果表明,桑黄乙酸乙酯提取物可能通过增强肾脏抗氧化状态来保护顺铂诱导的肾毒性。该提取物不干扰顺铂的抗肿瘤疗效。
