摘要
目的:探讨肥胖与雌激素的相互关系及对子宫的影响。方法:将48只SD大鼠随机分为6组:普通饮食组(A组)、高脂饮食组(B组)、去势后普通饮食组(C组)、去势后高脂饮食组(D组)、去势后雌激素替代普通饮食组(E组)、去势后雌激素替代高脂饮食组(F组)。每周检测体重,饲养14周后,进行腹腔注射葡萄糖耐量试验(IPGTT实验);16周后处死实验大鼠,取血清测量生化指标并比较各组大鼠的子宫直观表象及组织学改变。结果:缺乏雌激素会导致实验大鼠体重及内脏脂肪含量的增加。甘油三酯(TG)、血糖(GLU)、尿酸(UA)水平与雌激素水平负相关,TG水平与肥胖正相关,但各组指标差异不显著。雌激素缺乏与胰岛素抵抗有关,雌激素替代能够增加胰岛素敏感性并降低血糖。雌激素撤退会导致子宫萎缩,而给予替代雌激素后能明显促进子宫的生长发育。雌激素、肥胖与子宫内膜的增殖均为正相关关系。结论:雌激素与肥胖密切相关,两者均与子宫的生长发育和子宫内膜的增殖正相关。
