ABSTRACT

AIM: To investigate the effects of estrogen interference on ab dominal 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 and pro-menopausal were observed. Mice of 3 months old were randomly divided into c ontrol, ovariectomized (OVX), OVX+estrogen 15-days (E d 15 ) and OVX+ estrog en 60-days (E d 60 ) groups. Each group had 10 mice. Mice were raised and sa crificed until 7 months old after ovariectomized. 5 months and 10 months old mic e were divided into control, estrous cycle normal + estrogen 60 days, pro-menop ausal and pro-menopausal+60 days groups. 17?-estradiol time-release pellets ( 0.18 mg/pellet) were given ic in 15 days and 60 days before mice w ere sacrificed. RESULTS: The abdominal adipose weight in OVX gro up increased significantly (P 0.05 ). There was no difference in the abdominal adipo se weight between control and estrous cycle normal + estrogen 60-days groups, a nd between pro-menopausal and pro-menopausal+ estrogen 60-days groups. CONCLUSION: Ovariectomy significantly influences the metabolism of abd ominal adipose that causes adipose accumulation. Estrogen interference, especial ly long-term administration, can attenuate the abdominal adipose accumulation. Exogenous estrogen interference has no effect on abdominal adipose accumulation on cycle normal and pro-menopausal mice.
