[Immunologic and genetic markers of exposure to aromatic hydrocarbons in workers].

Workers exposed to aromatic hydrocarbons appeared to have prevalence of heterozygous variants of CYP1A1 gene (9893 A/G) and tumor necrosis factor gene reliably higher vs. the reference group 2.5 and 3.3 times respectively, and level of anti-benzene antibodies (IgG) increased vs. the reference group. The data presented demonstrate negative immunogenetic associations of aromatic hydrocarbons influence on oil extraction operators.
