A sample of silicon carbide dust taken in the field from a plant producing abrasives was studied in vitro. The SiC particles (part unmilled and part milled) were able to disturb the structure of erythrocyte membranes and to lead to blood red-cell lysis; they also either interfered with complement and activated the alternate pathway, or interacted with biological media and polymorphonuclear leucocyte...
N-Formyl-methionyl-leucyl-phenylalanine (F-MLP)-induced chemotaxis and luminol-amplified chemiluminescence were studied in isolated human polymorphonuclear leucocytes (PMN) and exposed to acrylonitrile (ACN) in vitro. Chemotaxis was reduced at ACN concentrations of 3 mm and above, while respiratory burst was affected at ACN concentrations of 18 mm and above. The ACN concentrations were highly correlated...
