[A comparative study of the dimensional variability in different cell types of the human adrenal cortex in the newborn infant and the adult].
The selection of the material for this study was governed by the idea that at the newborn like at the adult, the cortex of the adrenal gland is complete, including all the three zones, while medulla is not structured until 12-36 month; for this reason, we used only the cellular cortical elements. The quantitative method of evaluation of the cellular diameter, as well as the interpreting and correlation of the values with age, have confirmed that the dynamics of the cellular components of the adrenal gland depends on age, indicating significant differences. The cell diameter is usually bigger at the newborn compared with the adult (with zonal variations). The variability is relatively small which means that the individual values are placed in a limited field.
