[Flow volume curve evaluation of respiratory function in wolfram-molybdenum miners]. / Otsenka funktsii vneshnego dykhaniia po petle potok-ob"em u rabochikh vol'frammolibdenovogo rudnika.

The authors studied respiratory function in workers of wolfram-molybdenum mine where dust contains nearly 75% of silicon dioxide and considerable amounts of metals. The examinees were those with I stage silicosis and with silicosis complicated by chronic obstructive bronchitis. The respiratory disorders appeared most severe in association of the diseases.

[Comparative analysis of respiratory function in miners suffering from anthracosilicosis and silicosis]. / Sravnitel'nyi analiz funktsii vneshnego dykhaniia u gornorabochikh s antrakosilikozom i silikozom.

The authors revealed differences in pulmonary volumes, bronchial patency of bronchi at various levels, integral time of air transit in individuals having early anthracosilicosis and silicosis signs vs in healthy miners. During stage 1 of anthracosilicosis and silicosis respiratory function progressively deteriorates and demonstrates moderate disorders. When compared to anthracosilicosis ones, patients having polymetallic dust silicosis showed more significant decrease of the studied parameters.
