Roundness of epithelial nuclei in bronchial mucosa.

OBJECTIVE: To estimate the shape of epithelial nuclei in bronchial mucosa. STUDY DESIGN: Bronchoscopic mucosal samples from 12 patients with chronic bronchitis and 14 patients with squamous cell bronchial carcinoma were routinely processed and stained with the hematoxylin and eosin method. Fields with stratification and squamous metaplasia were selected. The roundness of epithelial nuclei was estimated using Lucia, version 3.51 ab, with an objective of 40:1 (NA = 0.65) and final magnification of 1,900:1. The images were manually edited. Roundness was calculated from area and perimeter. RESULTS: The mean roundness in stratification and squamous metaplasia in bronchial mucosa from carcinoma patients (0.90 +/- 0.04) was significantly greater than in bronchial mucosa from chronic bronchitis patients (0.80 +/- 0.006) (P < .05). CONCLUSION: Our results indicate that cell nuclei in stratification and squamous metaplasia in patients without bronchial cancer are more elongated than nuclei found under the same conditions in patients with squamous cell carcinoma.

Population projections, 1991-2021.

"This information presents initial assumptions and analyzes basic results of the latest population projections for Yugoslavia, and its constituent republics and provinces, by age and sex, for the period 1991-2021, which were prepared during 1995 through co-operation of the Federal Statistical Office and the Demographic Research Centre of the Institute of Social Sciences, and were published in 1996." The projections concern only the two republics that make up present-day Yugoslavia, that is Montenegro and Serbia (with its two regions of Vojvodina, and Kosovo and Metohija).

[The relationship between migration and age structure].

The author examines and compares the relationship between migration and age distribution in Yugoslavia using data for the populations of Kosovo and Vojvodina. "It is shown that in both cases migration had the same direction of effect (rejuvenation of the total population), but that the importance of the migration component in changing the age structure was less in Vojvodina than in Kosovo.... An examination is made of the influence of migration on changes in the age structure by way of an effect on fertility...." Data concern the period 1968-1981. (SUMMARY IN ENG)

Cysticercosis cerebri involving the lateral ventricle.

Cysticercosis cerebri involving the lateral ventricle is very rare. Two cases with such localization are presented. One of the patients, with occlusion of the foramen of Monro, was successfully treated by operation. A larval form in the lateral ventricle was revealed incidentally at autopsy in the second patient after rupture of a large basilar artery aneurysm.
