[The zona fasciculata of the adrenal glands 60 days after termination of exposure to chemical fertilizer]. / Snopovna zona nadbubreezne zlezde 60 dana nakon prestanka delovanja hemijskog gnojiva.

We detected fatty substances as well as enzymic activity in rats which, after a stay in workshop, where NPK fertilizer is produced, for 30 days survived another 60 days in normal conditions. The quantity of neutral fats and tryglycerides was reduced while the content of phospholipids was increased concerning the fasciculate's zone cells. After exposure to NPK fertilizer the cells nuclei got enlarged and dense. The activity of acid phosphatases increased, MAO was reduced, while the activity of succinat-dehydrogenesis was increased. The dermined quantities of fatty substances as well as the enzyme activity point to stimulated activity of fasciculate's zone cells.

[Stereometric characteristics of inflammatory gingival infiltrates]. / Stereometrijska karakteristika zapaljenjskog infiltrata gingive.

The aim of this paper was to assess stereometric characteristics of gingival cell infiltrate in regard to intensity of clinical inflammation. Materials used for assessment were 70 specimen of human gingiva removed during periodontal surgery therapy. Just before the surgery in the area where specimen was to be taken, intensity of clinical gingival inflammation was determined by gingival index after Loben. Considering stereometric parameters numerical density of lymphocytes and plasma cells were established. Analyzing results it was established that by increase of intensity of clinical gingival inflammation and increase of cell infiltrate occurs, whereas an increase of numerical plasma cells' density is statistically highly important (p < 0.001), while the numerical density of lymphocytes does not changes significantly (p > 0.05).
