Lymphocyte Subpopulation of Traffic Policemen in a Town of Central Italy (Preliminary Study)
Lymphocyte subpopulations were determined in 28 traffic policemen and in 14 male control subjects of a town in Central Italy. One half of each group was composed of smokers. The total number of lynphocytes and lynphocyte subpopulations, determined by flow-cytometric analysis, were not significantly altered in the traffic policemen who where smokers. Urinary lead (A toxic marker produced by vehicular traffic) was higher in the traffic policemen than in the control group; serum copper was slightly augmented in the traffic policemen and in all the smokers; serum zinc was not modified. Highly significant correlations were found between urinary lead and CD16+cells (mainly natural killer lynphocytes) and between serum copper and HLA-DR+ cells (B and activated T lymphocytes).
