求翻译：甲状腺组织有强大的浓集碘的能力，人的甲状腺每天需要60--80ug的碘以产生具有生理活性甲状腺激素。在体内，甲状腺所分泌的甲状腺激素和垂体所分泌的促甲状腺激素（TSH）间存在着相互依赖、相互制约的反馈关系，缺碘时，甲状腺细胞不能合成足够的甲状腺激素，血中甲状腺激素浓度下降，甲状腺激素对垂体分泌（TSH）的抑制作用减弱，垂体TSH的分泌增加，血中TSH水平升高，引起甲状腺肥大增生。是什么意思？

Thyroid tissue has a strong concentration of iodine capacity, the human thyroid gland day 60 - 80ug iodine to produce the biologically active thyroid hormone. Secretion of thyroid hormone in the body, thyroid and pituitary secretion of thyroid-stimulating hormone (of tsh) the existence of interdepen

There is a strong, thyroid tissue concentrations of iodine, the thyroid gland needs daily 60 - 80 ug of iodine to produce a physiological active thyroid hormone.

The thyroid gland organization has the formidable enrichment idodine ability, human's thyroid gland needs 60 every day--The 80ug idodine produces has the biological activity thyroxine.Presses thyroxine (TSH) which in vivo, which the thyroid gland secretes the thyroxine and the pituitary gland secret

Ability of the thyroid tissue there is a strong concentration of iodine, thyroid needs every day of people 60--80ug the physiological activity of iodine to produce thyroid hormones. In body, thyroid by secretion of thyroid hormone and pituitary by secretion of promoting thyroid hormone (TSH) between
