Abstract. Introduction. The protection of the reproductive health of the working-age population is the most important direction of State policy. In 5-15% of cases, the causes of reproductive dysfunction are immunological disorders. Benzene belongs to the group of industrial reprotoxicants, however, its effect of benzene on the reproductive system has not been sufficiently studied. Objective: to study the immunological aspects of the effect of benzene on the reproductive system. Methods. We examined 50 men exposed to benzene with reproductive disorders (26-49 years old), as well as 4 workers with normal sexual function aged 53-60 years. Spontaneous and induced changes in the cellular expression of apoptosis markers were studied. For the study, the ANNEXIN V-FITC/7-AAD kit was used for the detection of cells that have undergone apoptosis. The experiment was conducted in vitro using a biological medium (ejaculate). A factor of the chemical nature was benzene. Results. According to the results of the comparative analysis, there were no significant deviations of pathogenetic tests of immunological markers in comparison with the reference level in the spontaneous expression samples, but there was an excess of expression of the CD95 + cell death receptor (p<0.05) in 30% of the samples examined, and a decrease in the number of Annexin V-FITC+7AAD negative cells (without reaching the significance level) in samples with a load of (15%). There was a difference in the expression levels of CD95+ and CD25+ CD-reception indicators by 20% and 10% in relation to the spontaneous level (p<0.05). Representatives of the chemical group of aromatic hydrocarbons realize reprotoxicity, using the mechanism of excessive induction of the membrane signaling of the cell death receptor, accelerate the natural program of cell death by approximately 20% compared to the state of reproductive cells that were not stimulated. Conclusion. At the present stage, one of the tasks of occupational medicine is to study the effect of chemicals on the processes of reproduction, to develop new approaches to assessing the risk of their impact on the reproductive health of workers.

The potential relevance of prostanoid signaling in immunity and immunological disorders, or disease susceptibility and individual variations in drug responses, is an important area for investigation. The deregulation of Cyclooxygenase- (COX-) derived prostanoids has been reported in several immunoinflammatory disorders such as asthma, rheumatoid arthritis, cancer, and autoimmune diseases. In addition to the environmental factors and the genetic background to diseases, epigenetic mechanisms involved in the fine regulation of prostanoid biosynthesis and/or receptor signaling appeared to be an additional level of complexity in the understanding of prostanoid biology and crucial in controlling the different components of the COX pathways. Epigenetic alterations targeting inflammatory components of prostanoid biosynthesis and signaling pathways may be important in the process of neoplasia, depending on the tissue microenvironment and target genes. Here, we focused on the epigenetic modifications of inflammatory prostanoids in physiological immune response and immunological disorders. We described how major prostanoids and their receptors can be functionally regulated epigenetically and consequently the impact of these processes in the pathogenesis inflammatory diseases and the development of therapeutic approaches that may have important clinical applications.
