Abstract:
Changes in serum cholesterol and aminoterminal type III procollagen propeptide (PIIIPN) were compared in 33 patients with hyperthyroidism, 16 patients with hypothyroidism, and 23 healthy individuals. An increase in PIIIPN was found in patients with hyperthyroidism and an increase in serum cholesterol level was associated with hypothyroidism. There was no correlation between investigated indices. It is suggested that PIIIPN changes were a result of altered connective tissue metabolism, while serum cholesterol was related to the intensity of body metabolism.

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...
