Abstract:
Objective To identify the impact of estradiol on the goiter and the function of the thyroid gland with different dosages of estradiol.Methods 48 Wistar rats(female,normal state) were divided into 4 groups: Ⅰ,ovx,Ⅱ,sham;Ⅲ,ovx+E_(2)-low and Ⅳ ovx +E_(2)-large.In each group,we applied nuclide scanning of()~(131)I and()~(99)mTcO4 to detect the thyroid iodine uptake and adopted the technique of RT-PCR to test the expression of NIS.Quantity of TSH、FT_(3)、FT_(4) and the estradiol were examined.Results The expression of NIS was inhibited in group Ⅰ and group Ⅳ.Conclutions Estradiol can enhance the capability of the thyroid glands uptaking iodine and inhibit the expression of NIS and so estradiol is a very important component in the pathogenesis of goiter.
