[Cytochemical parameters in nasal mucosal and peripheral blood cells in beryllium production workers].

Nasal mucosal and peripheral blood cells from beryllium production workers underwent cytochemical tests for catecholamines and phospholipids and the activity of esterase and lysosomal cationic proteins. The established peripheral blood metabolic changes reflect reduced cell resistance in response to poor occupational factors and may be used in the rapid hygienic assessment of cytotoxicity of toxic substances.
