Effects of diesel exhaust particles on human neutrophil activation.

abstract：:The molecular events involved in both the initiation and development of silicosis are at present poorly defined, although mediators released from macrophages exposed to silica particles are believed to play a role. We have investigated the in vitro production of arachidonic acid (AA) metabolites in adherent bovine alv...
