[Cytochemical and immunological studies in workers exposed to organic solvents of paints and varnishes. II. Metabolism of the neutrophils].

In 39 workers, aged 24--56, occupationally exposed to organic solvents of paints and varnishes containing benzene, toluene and xylene, for 55--122 months, activity of peroxydase (Pox) and acid phosphatases (AcP) was determined. In addition, NBT test was carried out in peripheral blood neutrophils. Both AcP activity and spontaneous and stimulated NBT reduction were found to be increased. The authors believe that in people an insignificant exposure to organic solvents of paints and varnishes stimulates neutrophils metabolism.
