[Influence of occupational lead exposure on the concentration of immunoglobins and immune cellular functions in humans].
The evaluation of immunological conditions of 14 workers occupationally exposed to lead, and the comparison of these results with those of a non-exposed control group, with similar age and sex, were the aims of this study. It was determined the mean values of lead in blood. In exposed workers it was 46.9 micrograms/dl; while in the control group it was 10.9 micrograms/dl. Levels of immunoglobulin decreasing while increasing lead concentration in blood were found in those exposed. It was also found a significant lessening in the formation of rosette in relation to the control group.
