百部新碱与罗汉果皂苷Ⅴ联用对小鼠的镇咳、祛痰作用研究

摘要

OBJECTIVE:To study the relieving cough and eliminating phlegm effects of stemoninine combined with mogrosideⅤ on mice,and select its optimal ratio. METHODS:70 mice were selected in each experiment and randomly divided into 7 groups,namely solvent group(normal saline), codeine(15 mg/kg)or ambroxol(30 mg/kg)group(positive control),stemoni-nine group(30 mg/kg),mogroside Ⅴ group(30 mg/kg),stemoninine-mogroside Ⅴ combination group(30 mg/kg)with mass ra-tio of 2:1,1:1,1:2,ig,once a day. Ammonia-induced cough experiment(positive drug was codeine)and tracheal phenol red ex-cretion experiment(positive drug was ambroxol)were respectively conducted. Using cough latent period,cough times and volume of tracheal phenol red excretion as indexes,the antitussive and expectorant effects of drug in each group were compared. RE-SULTS:Compared with solvent group,cough latent period was obviously shortened,cough times was obviously reduced,volume of tracheal phenol red excretion was obviously increased in each administration group(P<0.05 or P<0.01). Compared with mogro-side Ⅴ group,cough latent period was obviously shortened,cough times was obviously reduced in stemoninine-mogroside Ⅴgroup with different mass ratios(P<0.05),and 2:1,1:1 groups showed the best effects. Compared with stemoninine group,vol-ume of tracheal phenol red excretion was obviously increased in stemoninine-mogroside Ⅴ group with different mass ratios (P<0.05),and 1:1,1:2 groups showed the best effects. CONCLUSIONS:The combination of temoninine and mogroside Ⅴ shows synergistic effects on relieving cough and eliminating phlegm,stemoninine-mogrosideⅤmass ratio of 2:1,1:1 can be used as pre-ferred combination of reference.%目的:研究百部新碱与罗汉果皂苷Ⅴ联用后对小鼠镇咳、祛痰作用的影响,并筛选其最优配比.方法:各实验均选70只小鼠随机分为7组,分别为溶剂组(生理盐水)、可待因(15 mg/kg)或氨溴索(30 mg/kg)组(阳性对照)、百部新碱组(30 mg/kg)、罗汉果皂苷Ⅴ组(30 mg/kg)和质量比分别为2:1、1:1、1:2的百部新碱-罗汉果皂苷Ⅴ联用组(30 mg/kg),ig给药,每天1次.分别进行氨水致咳实验(阳性药物为可待因)和气管酚红排泌实验(阳性药物为氨溴索),以咳嗽潜伏期、咳嗽次数和气管酚红排泌量为指标,比较各组药物的镇咳、祛痰作用.结果:与溶剂组比较,各给药组小鼠的咳嗽潜伏期明显缩短、咳嗽次数明显减少、气管酚红排泌量明显增加(P<0.05或P<0.01);与罗汉果皂苷Ⅴ组比较,百部新碱-罗汉果皂苷Ⅴ不同配比组小鼠的咳嗽潜伏期明显缩短、咳嗽次数明显减少(P<0.05),且以2:1、1:1配比组效果较好;与百部新碱组比较,百部新碱-罗汉果皂苷Ⅴ不同配比组小鼠的气管酚红排泌量明显增加(P<0.05),且以1:1、1:2配比组效果较好.结论:百部新碱与罗汉果皂苷Ⅴ联用后对镇咳、祛痰具有协同作用,可以百部新碱-罗汉果皂苷Ⅴ质量比为2:1、1:1作为该组合配比优选的参考.
