title: Aspects of the thyroid gland vascularization in young organisms (a morphological and radioisotope-based study).
abstract: The thyroid gland vascularization has been studied on 58 pieces belonging to young organisms (human and animal) by means of both morphometric methods (macro- and microscopic) and injection of radioisotopes (86Rb). The statistical-mathematical study of the dimensional values characterizing the thyroid vascular branch at different levels assumed for study allowed to determine the thyroid central area as the best vascularized of the thyroid parenchyma. Estimating the specific activity and the absorption constant value of the 86Rb in the vascular wall and the glandular parenchyma, the radioisotope-based study attests the data obtained morphologically. By the simultaneous injection of 86Rb into strychnine, the pharmacodynamic study shows a more prominent reduction of the 86Rb absorption constant value in the distal area of the gland as compared to its central one and the blank batch.
