[Indicators of immunity and acute phase reaction in men in relation to the duration of exposure to mercury vapors].

The indices of immunity and acute phase reaction in 89 men exposed for 2 to 26 years to mercury vapours were assessed on the basis of immunoglobins, lysozyme, C3c, C4, alpha 1-acid glycoproteins, haptoglobin and ceruloplasmin concentrations in blood serum. Urinary mercury concentration amounted to 73 +/- 60 micrograms x l-1 whereas in blood it did not exceed 50 micrograms x l-1. A decrease in concentration of IgA, IgG and lysozyme in persons who worked for over 20 years was found. The observed phenomenon did not affect the anti-infection and antitumor immunity of the workers.
