藿香正气水中中药成分对大鼠体内乙醇代谢的影响

Effect of the Chinese Herbal Medicinal Ingredients in Huoxiang Zhengqi Liquid on Alcohol Metabolism in Rats

目的研究服用藿香正气水后,大鼠体内乙醇含量及药代动力学参数的变化。方法将大鼠随机分为3组,分别按3.0 m L/kg剂量灌胃白酒、低浓度中药酒和高浓度中药酒,于给药前(0 min)和给药后5 min、10 min、15 min、30 min、1 h、2 h、3 h、4 h、5 h、6 h、8 h断尾采血,用顶空-气相色谱法测定大鼠血液中的乙醇含量,用DAS 2.0软件计算乙醇的药代动力学参数,SPSS 17.0软件对药代动力学参数进行分析。结果高浓度中药酒组与白酒组最大血药浓度相比,差异有统计学意义(P<0.05);其他药代动力学参数在三组间差异均无统计学意义(P>0.05)。结论藿香正气水中中药成分对大鼠体内乙醇代谢和消除无明显影响。本研究对涉及饮用藿香正气水导致的交通案(事)件的定性判定和处理以及药物间的相互作用研究具有参考意义。

Objective To study the changes of alcohol content and pharmacokinetic parameter in rats after taking Huoxiang Zhengqi liquid. Methods The rats were randomly divided into three groups and given with white alcohol at the dose of 3.0mL/kg, low-dose and high-dose Chinese medicine liquor, respec-tively. The blood was collected before administration and 5 min, 10 min, 15 min, 30 min, 1 h, 2 h, 3 h, 4 h, 5 h, 6 h and 8 h after administration by cutting rats,tails. The concentrations of alcohol in blood were detected by headspace-gas chromatography method. The main pharmacokinetic parameters were calculated by DAS 2.0, and then analyzed by SPSS 17.0. Results The difference of maximum blood concentrations between high-dose Chinese medicine alcohol group and white alcohol group was statistically significant （P〈0.05）. There was no significant difference in other pharmacokinetic parameters among three groups （P〉0.05）. Conclusion The Chinese herbal medicinal ingredients in the Huoxiang Zhengqi liquid has no effect on the metabolism and elimination of ethanol in rats. The research provides useful reference for the qualitative assessment and processing of traffic accident cases involved in Huoxiang Zhengqi liquid and the studies related to drug-interaction.
