摘要 目的:观察滋阴泻火中药对辛基酚和双酚A染毒大鼠子宫、卵巢的雌激素受体(ER)、芳香化酶(AR)、胰岛素样生长因子(IGF-Ⅰ)基因和蛋白表达的影响,探讨中药拮抗环境内分泌干扰物(EEDS)拟雌激素活性的作用机制。方法:3周龄雌性SD大鼠染毒组给予辛基酚和双酚A联合喂饲,治疗组给予滋阴泻火中药与染毒物同时喂饲,对照组喂饲玉米油,每天灌胃1次,连续14天,分别检测子宫湿重及脏器系数,子宫、卵巢的ER、AR、IGF-Ⅰ基因和蛋白表达。结果:染毒组与对照组比较子宫湿重及脏器系数增加,子宫、卵巢ER、AR、IGF-Ⅰ基因和蛋白表达均上调,治疗组与染毒组比较,子宫湿重及脏器系数降低,子宫、卵巢ER、AR、IGF-Ⅰ基因和蛋白表达均下调。结论:EEDS对生殖器官具有显著的拟雌激素作用,而滋阴泻火中药EEDS对的拟雌激素活性具有拮抗作用,中药的治疗干预可使生殖器官ER、AR、IGF-Ⅰ的基因和蛋白表达显著下调,从而显著降低生殖器官对EEDS的敏感性,这可能是中药有效拮抗EEDS拟雌激素活性的作用机制。 目的:观察滋阴泻火中药对辛基酚和双酚A染毒大鼠子宫、卵巢的雌激素受体(ER)、芳香化酶(AR)、胰岛素样生长因子(IGF-Ⅰ)基因和蛋白表达的影响,探讨中药拮抗环境内分泌干扰物(EEDS)拟雌激素活性的作用机制。方法:3周龄雌性SD大鼠染毒组给予辛基酚和双酚A联合喂饲,治疗组给予滋阴泻火中药与染毒物同时喂饲,对照组喂饲玉米油,每天灌胃1次,连续14天,分别检测子宫湿重及脏器系数,子宫、卵巢的ER、AR、IGF-Ⅰ基因和蛋白表达。结果:染毒组与对照组比较子宫湿重及脏器系数增加,子宫、卵巢ER、AR、IGF-Ⅰ基因和蛋白表达均上调,治疗组与染毒组比较,子宫湿重及脏器系数降低,子宫、卵巢ER、AR、IGF-Ⅰ基因和蛋白表达均下调。结论:EEDS对生殖器官具有显著的拟雌激素作用,而滋阴泻火中药EEDS对的拟雌激素活性具有拮抗作用,中药的治疗干预可使生殖器官ER、AR、IGF-Ⅰ的基因和蛋白表达显著下调,从而显著降低生殖器官对EEDS的敏感性,这可能是中药有效拮抗EEDS拟雌激素活性的作用机制。
