摘　　要：目的利用代谢动力学等相关技术研究马兜铃酸I对小鼠肝脏代谢酶的影响,揭示马兜铃酸I影响小鼠肝脏代谢功能的作用机制。方法取雄性6周龄C57BL/6小鼠作为研究对象,按照设定的马兜铃酸I剂量随机分为4个给药组和l个正常对照组,灌胃给药,每周5天,连续4周,利用代谢动力学相关技术和分子生物学手段研究马兜铃酸I对小鼠肝脏代谢酶的影响。结果显示马兜铃酸I可以诱导小鼠肝脏细胞色素P4501a2和细胞色素P4503a11的酶活性和mRNA表达,也可以通过诱导磺基转移酶增加吲哚酚硫酸的含量,但不是主要因素。AAI引起的肾毒性是吲哚酚硫酸在血浆、肝脏和肾脏蓄积的主要原因,反过来也加重了AAI引起的肾脏毒性。结论马兜铃酸I对小鼠肝脏代谢酶有多重影响。Objective To determine the effect of aristolochic acid I(AAI) on the liver metabolic enzymes of mice and the associated mechanism using metabolic kinetics and related techniques. Methods Male 6-week-old C57 BL/6 mice were assigned to four treatment groups and one control group. Established doses of AAI(0.2, 2, 10, and 20 mg/kg) were administered intragastrically 5 days per week for 4 weeks. The effects of AAI on liver metabolic enzymes were determined using metabolic kinetics and molecular biology techniques. Results AAI induced enzyme activities and mRNA expressions of liver cyp1a2 and cyp3a11, and increased the content of indoxylsulfuric acid by inducing sulfotransferase(SULT1B1). However, renal toxicity induced by AAI was the main cause of the accumulation of indoxylsulfuric acid in the plasma, liver, and kidney, which in turn aggravated the renal toxicity caused by AAI. Conclusion AAI has multiple effects on liver metabolic enzymes in mice.
