In most iodine-proficient human populations without thyroid disease, the mean, median and 97.5 centile for circulating concentrations of thyroid-stimulating hormone are progressively higher in adults over 80 years of age compared with middle-aged (50–59 years) and younger (20–29 years) ...
Morphometric studies on the development of the human thyroid gland. II. The late fetal life. Moreover, the epithelium/colloid ratio in the thyroid gland, a very sensitive parameter of stimulation of the glands by TSH, was calculated. Regarding ... J Bocian-Sobkowska,W Woźniak,LK Malendowi...
The aim of this study was to evaluate the morphological and biochemical maturation of the thyroid gland in human neonates. The mean iodine concentration in the thyroid gland of very premature infants (less than 32 weeks gestational age, 0-3 days survival, n = 12) was significantly lower than...
The purpose of this study was to establish a "normal" range of dimensions of the thyroid gland on routine neck computed tomography in the Korean population and to investigate the possible influence of some physiological factors on the thyroid dimension. Neck computed tomography scans of 100 adults...
