Abstract:
Immediately after application of various contrast media a number of functional parameters of thyroid function were determined. Especially after application of Biliscopin which is strongly bound to plasma proteins, a significant rise of the free thyroid hormone fractions, a significant increase in the binding capacity of specific transport proteins and a decrease of the total concentration of thyroid hormones was noticed. It is therefore recommended that neither in the early phase within the first hour, nor in the late phase within 10 days after application of contrast media, blood for determination of parameters of thyroid function should be collected, since otherwise misleading results may be obtained.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
