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.
本研究旨在评估14名职业性接触铅的工人的免疫状况，并将这些结果与年龄和性别相似的非接触对照组的结果进行比较。测定了血铅的平均值。接触铅的工人血铅平均值为46.9微克/分升；而对照组为10.9微克/分升。在接触铅的人群中发现，随着血铅浓度升高，免疫球蛋白水平下降。与对照组相比，还发现玫瑰花结形成明显减少。
