Abstract
Cytogenetic biomarkers, such as micronuclei in peripheral blood or oral mucosa, are widely used for evaluation of exposure to genotoxins or carcinogens. Tobacco is one of the strongest carcinogens, responsible for development of different types of cancers. The aim of this study was to assess the genotoxicity of cigarette consumption in young smokers and to correlate results of cytogenetic analysis in peripheral blood lymphocytes and exfoliated buccal cells. The study was conducted on samples taken from 43 smokers and 44 non-smokers, young individuals from Bosnia and Herzegovina. Significantly higher frequency of micronuclei in peripheral blood lymphocytes was observed in smokers (p < 0.05). No significant correlations were found for age, duration and intensity of smoking, and frequency of micronuclei in lymphocytes. Significantly higher frequency of degenerated (apoptotic) buccal cells was also revealed in smokers (p < 0.05). The frequency of apoptotic cells in smokers was significantly influenced by the age of participants (F = 8.649; p < 0.01) and duration of smoking (F = 5.389; p < 0.05). Results of cytogenetic analysis conducted in peripheral blood and exfoliated buccal cells are in significant positive correlation, indicating complementarities of those analyses.
