[Immunoelectrophoretic data and serum immunoglobulin G, A and M levels in workers engaged in the production of organophosphate pesticides].

Immunoelectrophoresis of serum proteins and concentrations of IgG, IgA and IgM in serum were estimated in 83 workers employed at the production of organic phosphorus insecticides. In 56.6% of immunoelectrophorograms deviations from normal were found, most frequently a rise of acute phase proteins and IgG. Quantitative determinations showed a rise of serum IgG and IgA and a fall of IgM concentrations as compared to a control group of nonexposed persons.
