Comparative cytomorphometric and cytospectrophotometric investigations of gastric lesions.

Comparative cytomorphometric and cytospectrophotometric investigations have been carried out on Hematoxylin-Eosin and Feulgen stained paraffin sections from 150 patients with normal gastric mucosa, chronic atrophic and hypertrophic gastritis, benign and malignantly transformed stomach ulcers and adenomatous polyps and adenocarcinoma of the stomach. The changes in the small and large nucleus (cell) diameters; nucleus, cell and cytoplasma area (volume) and nucleus/cell and nucleus/cytoplasma ratio for area and volume as well as the nuclear DNA content values have been presented in the pathway from normal stomach mucosa to gastric cancer. The presented results give us more information about the dynamics of malignant cell transformation.

[Morphologic study of teflon implanted in the prelaryngeal space of dogs].

The authors described their experimental studies on dogs, using aliomaterial teflon- in forming FTM slap in the prelaryngieal space for the purposes of the reconstructing plastica of the larynx. The teflon was a suitable material because of its good tolerance and well occuring reactions of the pathologic organization, combined with the processes of resorption and its substitution with connective tissue. The authors found the period of 10 to 20 days as the earliest and most suitable period for the usage of FTM slap.
