Abstract

In this study, we investigated the immunotoxicities of polycyclic aromatic hydrocarbons in 54 automobile emission inspectors and in 84 control subjects, and evaluated associations between immunological and genotoxicological parameters. Specific surface antigens of peripheral lymphocytes, namely, CD3, CD4, CD8, CD19, and CD69 were subjected to measure immune status in automobile emission inspectors and control subjects. T-and B-cells showed no significant differences between automobile emission inspectors and control subjects (p = 0.740 and 0.395). In addition, the ratio of T helper cells to T cytotoxic cells was not deferent (p = 0.144). However, T-cell activation was found to be significantly higher in automobile emission inspectors (p = 0.041), but not B-cell activation. The levels of two cytokines (IL-4 an INF-γ) and four immunoglobulins (IgA, IgE, IgG, and IgM) were also determined in automobile emission inspectors and control subjects. All immunoglobulin types were lower in automobile emission inspectors, but this was significant only for IgG (0.047). In addition, the levels of two cytokines, IL-4 and INF-γ, were also higher in automobile emission inspectors, though this was not significant. DNA damage in mononuclear and polynuclear lymphocytes and in the level of urinary metabolites, 1-OHP and 2-naphthol, were evaluated in automobile emission inspectors and in control subjects and significant differences were found between the two groups. Examinations of urinary metabolites, DNA damage, and immunological parameters, including leukocyte subpopulations, immunoglobulins, and cytokines, showed that the cytokines levels were associated with the levels of two urinary metabolites, 1-OHP and 2-naphthol.
