[Filamentary granules in human bronchi].

Mucous cells of human bronchial glands contain secretory granules with 5,5-7 nm parallel filaments. In contrast with the glycoproteic-rich mucous granules, filamentary granules exhibit weak reactivity with tannic acid, indicative of proteins. Exocytosis or discharge in glandular lumen are sometimes observed.

[Endothelial cells and adhesion of red cells in diabetes and sickle cell anemia. Quantitative and qualitative aspects].

Endothelial cell alterations are considered to be a primary event in thrombosis and atherosclerosis. The adhesion of red cells from diabetic patients or patients with sickle cell anemia was measured using endothelial cell culture and a radiometric technique. The adhesion was significantly increased (P less than 0.

[A case of occupational benzene poisoning combined with tricholeukocytic leukemia].

Case report of occupational intoxication, with moderate anemia and hypogranulocytosis, in the course of which occurs a hairy cell leukemia. Cytological data are significative in photonic and electronic microscopy: microvilli and granulo-lamellar complexes. Discussion of benzen, as toxic factor in etiology of this leukemia.
