摘要: 目的 研究雌激素干预对雌性C57BL/6J 小鼠腹腔脂肪代谢的影响。方法 采用卵巢切除法造成雌激素缺乏模型,以及在动情周期正常和围绝经期的小鼠中,给以雌激素干预,观察腹腔脂肪重量的变化。3 mon 龄小鼠随机分为正常组,卵巢切除组,给雌激素15 d 组和给雌激素60 d 组,每组10 只。小鼠摘除卵巢后饲养至7 mon 龄处死。5 和10 mon 龄小鼠分为正常组,动情周期正常+雌激素60 d组,围绝经期组和围绝经期+雌激素60 d 组,每组10只,分别饲养至7 和12 mon 龄处死,检测腹腔脂肪重量。各组小鼠于处死前15 和60 d 分别皮下埋植控释雌激素(17β-雌二醇)药丸(0 .18 mg/丸)。结果 卵巢切除组腹腔脂肪重量明显增加(P<0 .05);给雌激素15 d 组腹腔脂肪重量减轻(P<0 .05);给雌激素60 d 组腹腔脂肪重量有明显减轻,与正常组比较无显著性差别(P>0 .05)。动情周期正常+雌激素组和围绝经期+雌激素组的小鼠,其腹腔脂肪重量的变化无差别。结论 卵巢切除明显影响小鼠的脂肪代谢导致腹腔脂肪积聚,而雌激素干预,特别是长期应用,可以明显减少小鼠的腹腔脂肪积聚。外源性雌激素干预在动情周期正常和围绝经期对小鼠腹腔脂肪没有明显的影响。

Abstract: AIM: To investigate the effects of estrogen interference on abdominal adipose accumulation in C7BL/6J mice.METHODS: Estrogen was administrated to the ovariectomized mice(estrogen-deprived model)and the changes of abdominal adipose weight of the mice in the normal estrous cycle andPro-menopausal were observed.Mice of 3 months old were randomly divided into control,ovariectomized(OVX),OVX +estrogen 15-days(E d 15)and OVX + estrogen 60-days(E d 60)groups.Each grouPhad 10 mice.Mice were raised and sacrificed until 7 months old after ovariectomized.5 months and 10 months old mice were divided into control,estrous cycle normal +estrogen 60 days,pro-menopausal andPro-menopausal +60 days groups.17β-estradiol timereleasePellets(0.18 mg/pellet)were given ic in 15 days and 60 days before mice were sacrificed.RESULTS: The abdominal adipose weight in OVX grouPincreased significantly(P<0.05).The abdominal adipose weight in E d 15 grouPshowed slightly decreased,but was still significant difference(P<0.05).The abdominal adipose weight in E d 60 grouPdecreased significantly and showed no difference compared to control grouP(P>0.05).There was no difference in the abdominal adipose weight between control and estrous cycle normal + estrogen 60-days groups,and betweenPro-menopausal andPro-menopausal + estrogen 60-days groups.CONCLUSION: Ovariectomy significantly influences the metabolism of abdominal adipose that causes adipose accumulation.Estrogen interference,especiallylong-term administration,can attenuate the abdominal adipose accumulation.Exogenous estrogen interference has no effect on abdominal adipose accumulation on cycle normal andPro-menopausal mice.
