Título Dust levels and lung and bronchial biochemical changes in silicotic foundry workers
Título original Obsah prachu a biochemické změny v plicích a bronšich u silikózy zaměstnanců sléváren [en checo]
Información bibliográfica July 1979, Vol.31, No.6-7, p.222-225. 15 ref.
Resumen Results of pathological examination of the lungs of 3 deceased workers are reported: the quantity of dust deposited in the upper right lobe was, 1,022, 2,431, and 3,073g respectively, or 3.64, 3.76 and 7.4g/100g dust-free dry matter. Total silica accounted for 22.31 and 37.29% of the dust in 2 cases, and 7.53% in the third. Detailed investigation of a lung with complicated silicosis showed a greater concentration of total dust and total silica in pseudotumoral nodules than in the rest of the lung tissue, both in absolute terms and in relation to the dust-free dry matter. The lung hydroxyproline concentration was higher in foundry workers than control cases, and pneumoconiotic miners. The bronchi of the silicotic subjects contained less dust than the lung parenchyma and their biochemical properties were not affected.
