[Thyroid glands as an object of morphometric study].

Standardization of the morphometric studies of the thyroid is performed. The following table for a semiquantitative analysis of thyroid morphofunctional state is given: 1) epithelial components with characteristics of main cell types and their proliferative activity; 2) stromal components; 3) some pathologic changes (cyst, hemorrhages, etc.).

[Morphofunctional characterization of Apud cells in the human rectum in tumor growth].

Under normal conditions the number and proportion of four main cell types of Apud cells (EC, DI, D, L) is stable. The number of Apud cells is always lower when adenomas or adenocarcinomas are present. A decrease of Apud cells number is inversely proportional to the degree of dysplasia.
