摘要: 目的: 观察甘草水煎液对大鼠肝细胞色素P450酶活性的影响。方法: SD大鼠随机分为4组,分别为空白对照组(给予生理盐水)、酶诱导剂组(给予苯巴比妥)、酶抑制剂组(给予西咪替丁)及甘草水煎液组(给予甘草水煎液),各组动物连续灌胃给药 14 d,第15天 腹腔注射探针药物非那西丁,不同时间点采集血样后,HPLC法测定血浆中非那西丁浓度,并估算其药代动力学参数。结果: 生理盐水组、苯巴比妥组、西咪替丁组及甘草水煎液组非那西丁的t1/2分别为(104±10)、(178±15)、(86±9)、(90±9) min。结论: 甘草水煎液对大鼠肝药酶P450具有一定的诱导作用。

Abstract: AIM: To investigate the effects of Glycyrrhiza uralensis decoction on liver cytochrome P450 in rats.METHODS: SD rats were randomly divided into four groups (control, enzyme inducer, enzyme inhibitor and Glycyrrhiza uralensis decoction groups) and drugs were administrated through intragastric route for 14 days. Control group were treated with saline, enzyme inducer group were treated with 3.0 mg/kg phenobarbital, enzyme inhibitor group were treated with 40 mg/kg cimetidine and Glycyrrhiza uralensis decoction group were treated with 1.0 g/kg decoction, respectively. Phenacetin, which used as a probe drug, was given to all rats by intra-peritoneal injection on the 15th day. The blood samples were collected at different time points. A developed HPLC method was introduced to determine the concentration of the probe drug in rat plasma and Das software was used to estimate the pharmacokinetic parameters.RESULTS: The t1/2 value of probe drug in groups of control, enzyme inducer, enzyme inhibitor and Glycyrrhiza uralensis decoction were (104±10),(178±15),(86±9) and(90±9) min, respectively.CONCLUSION: Glycyrrhiza uralensis decoction has inductive effects on rat liver CYP450.
