摘要
[目的]观察杜仲三个部位对肾阳虚小鼠的抗氧化和抗抑郁作用,为认识杜仲"甘温,入肝、肾经"药性的现代科学内涵提供药效学基础。[方法]ICR雄性小鼠,随机分为正常对照组,模型对照组,桂附地黄丸组,杜仲水部位组、正丁醇部位组、乙酸乙酯部位组。采用腹腔注射苯甲酸雌二醇造成小鼠肾阳虚模型。对小鼠抗氧化指标(SOD、GSH-Px、CAT活性及MDA含量)、抗抑郁指标(悬尾、MAO活性)、疲劳指标等进行测定。[结果]抗氧化指标:杜仲三个部位都能降低MDA含量、提高SOD活性,杜仲水部位和正丁醇部位能提高CAT活性,杜仲水部位和乙酸乙酯部位能提高GSH-Px活性。抗抑郁指标:杜仲乙酸乙酯部位能提高小鼠悬尾活动时间,杜仲三个部位均能抑制MAO活性。杜仲三个部位都能提高小鼠奔跑时间和距离。[结论]杜仲可改善肾阳虚衰引起的衰老和抑郁,其抗氧化和抗抑郁作用可认为是其"甘,温,归肝、肾经"主要药效群的组成部分。杜仲水部位和正丁醇部位的药效较类似,可能是其主要的药效群物质基础。
[Objective] To observe the effects of different fractions from Cortex Eucommiae on oxidation resistance and anti-despondent of Extradiol-induced kidney-yang deficiency mice,and understand the modern scientific connotation of the properties theories about sweet-flavor,warm-nature,meridian tropism in liver and kidney.[Methods] Healthy adult male ICR mice were divided into six groups randomly：normal control group,model control group,positive control group（Guifudihuang）,three groups of Cortex Eucommiae（water fraction,n-butanol fraction,and acetoacetate fraction）.Kidney-yang deficiency mice model was established with intraperitoneal injection of estradiol benzoate.The determined indexes included oxidation resistance indexes（activity of SOD,GSH-Px,CAT,content of MDA）,anti-despondent indexes（tail suspension,activity of MAO）,and anti-fatigue ability.[Results] Oxidation resistance indexes：Three fractions of Cortex Eucommiae all could decrease content of MDA,enhance activeness of SOD.The water and n-butanol fraction could enhance activeness of CAT.The water and acetoacetate fraction could enhance activeness of GSH-Px.Anti-despondent indexes：The acetoacetate fraction of Cortex Eucommiae could lengthen the activity time in tail suspension test,and three fractions of Cortex Eucommiae all could decrease activeness of MAO.Three fractions of Cortex Eucommiae all could lengthen the running distance and time.[Conclusion] Cortex Eucommiae could improve aging and depression caused by kidney-yang deficiency.Oxidation resistance and anti-despondent effects could be an important part of the main effective groups about sweet-flavor,warm-nature,meridian tropism in liver and kidney.The effects of water extract and n-butanol extract were closer and stronger,which could be the main substance basis of common effective groups.
