摘    要:研究芦丁对哺乳母鼠乳腺发育、泌乳相关激素水平及其受体表达量的影响。试验选择18只wistar哺乳母鼠,随机分为3组,分别为对照组(LacCon组)每日每只灌喂生理盐水(2ml)1次;芦丁组(Lac Rut组)每日每只灌服芦丁(60mg/kg,BW)1次;雌二醇组(LacEst组)每周每只肌注(60μg/kg,BW)1次;从哺乳第4天开始连续给药2周,基础日粮相同。检测哺乳母鼠血浆与乳腺组织中雌激素(雌二醇,E2)、孕激素(P)、催乳素(PRI,)和生长激素(GH)的含量,乳腺组织中雌激素受体(雌激素α受体,ERR)、孕激素受体(PR)、催乳素受体(PRLR)和生长激素受体(GHR)的表达量,并进行乳腺组织切片组织形态学观察。试验显示:E2、PRL和GH在血浆与乳腺组织里的含量都表现为Lac—Est组〉Lac~Rut组〉LacCon组(P〈0.05);P含量组间差异不显著(P〉0.05);ER、PR、PRLR和GHR在乳腺组织中的表达量均为Lac—Est组〉LaCRut组〉Lac—Con组(P〈0.05);乳腺腺泡/管腔直径统计显示Lac-Est组和LacRut组高于LacCon组(P〈0.05),LacEst组与LacRut组差异不显著(P〉0.05)。试验结果表明,芦丁能够提高哺乳母鼠体内E2水平,促进PRL和GH分泌,诱导ER、PR、PRLR和GHR的表达,具有弱雌激素样作用功效。

关 键 词:芦丁  大鼠  激素  受体

Abstract:The objective of this study was to observe effects of a natural plant extract rutin in mammary gland development,endocrine hormone levels and receptor expression were measured for lactation rats.Eighteen Wistar rats were randomly assigned to three treatments:control(Lac-Con) group was treated with gastric infusion of 2 mL normal saline per mouse per day;Rutin(Lac-Rut) treatment group was treated with gastric infusion of rutin 60 mg/kg BW per day;and Estradiol(Lac-Est) group was treated with intramuscular in...
Keywords:rutin  rat  hormone  receptor
