[Cellular metabolism in nasal lining and buccal epithelium in coal miners].

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.
