Article	Year
[Cellular metabolism in nasal lining and buccal epithelium in coal miners]. Meditsina truda i promyshlennaia ekologiia, 2007, Issue:4 The authors used cytoche mical methods to study functions of cells in nasal lining,buccal epithelium and peripheral blood of coal miners suffering from anthracosilicosis stage I. Findings were lower activity of ATPase, increased activity of acid phosphatase with partial and complete diffusion of products, higher levels of phospholipids, glycosaminoglycans and glycogen in comparison with those in apparently healthy individuals. These tests are expedient for diagnosis of anthracosilicosis at early stages in miners. Topics: Acid Phosphatase; Adenosine Triphosphatases; Adult; Anthracosilicosis; Biomarkers; Blood Cells; Cheek; Coal Mining; Early Diagnosis; Glycogen; Glycosaminoglycans; Histocytological Preparation Techniques; Humans; Male; Mouth Mucosa; Nasal Mucosa; Phospholipids	2007
[A comparative morphological and enzyme-histochemical study of experimental pneumoconiosis and experimental allergic-hyperergic pulmonary granuloma (author's transl)]. Praxis und Klinik der Pneumologie, 1979, Volume: 33 Suppl 1 Six endotracheal applications of 15 milligrams of cadmium sulfide (CdS) given to rats at weekly intervals induce pneumoconiosis with massive adhesions. The same quantities of lead sulfide (PbS) given under the same conditions have much less effect, causing only the formation of fairly small fibrous nodules. The tissue reactions to CdS and PbS were studied morphologically (light and electron microscope) and enzyme-histochemically. The results were compared with those observed in experimental anthracosilicosis in rats and with those seen in allergic-hyperergic reactions of the lung in guinea pigs (induced by several applications of the complete Freund adjuvans). A considerable increase in macrophages in the alveoli and interstices of the lungs with increased activity of acid phosphatase and oxydoreductases had occurred in every animal. None showed primary damage to type 2 pneumocytes. The results indicate that the two toxic agents differ in their capacity to induce fibrosis not because they interfere to a different degree with the clearing function of the lung or surfactant production, but because they differ in their capacity to stimulate fibroblast formation.
