[The importance of preoperative fine needle aspiration cytology for the evaluation of thyroid gland nodes].

The results of cytologic assessment of 2,287 aspirates from 2,200 patients with thyroid nodules (two thirds of which were "cold") are presented. The classification scheme proposed by Weiss and Pilz was used. The high predictive value of aspiration cytology in this clinical setting made it possible to limit surgical exploration to 10.

[Morphological studies of the endocervical epithelium].

The three cellular components of endocervical epithelium were studied by means of optical light microscopy and electron microscopy. Particular attention was given to cytochemical responses to attempts by which to detect mucus in cylindrical epithelium. The beaker cells were grouped by stages by means of electron microscopy.
