[Structural and functional-metabolic criteria for studies of bronchial lavage cells in beryllium production workers]

The article presents results of cytomorphologic and cytochemical studies of bronchoalveolar lavage cells in experimental animals and in beryllium production workers having beryllium intoxication signs. Findings are increased counts of degenerated neutrophils and macrophages in bronchial lavage, high degree of microbial (streptococcal and staphylococcal) contamination in workers having atrophic bronchitis, low levels of catecholamines and esterase activity, high content of phospholipids, if compared to apparently healthy individuals. These tests are expedient to use in early diagnosis among beryllium production workers.
