Abstract

Morphometric indices, structural components in fetuses and newborns were studied depending on gestation and morphofunctional variant. The object of the study was 130 thyroid glands obtained from fetuses and deceased newborns, from 22 full to 40 weeks of gestation. The average thyroid volume in fetuses and newborns in the Republic of Sakha (Yakutia) exceeded the thyroid volume of the non-endemic iodine in the region of St. Petersburg. The morphofunctional activity of the thyroid gland in children of the early and late neonatal period, compared with data from the iodine-non-edemic region, remains high and indicates a delay in morphological differentiation of the fetal gland in the focus of iodine insufficiency. It was revealed that stromal structural components of the gland are more pronounced in fetuses and newborns of Yakut nationality, and in children of Russian nationality had structural components of parenchyma.
