In recent years, a number of studies have suggested that lichens might be the easily accessible sources of natural drugs that could be used as a possible food supplement. Extensive research is being carried out to explore the importance of lichen species, which are known to contain a variety of pharmacological active compounds. On the other hand, imazalil (IMA), a commonly used fungicide in both agricultural and clinical domains, is suspected to produce very serious toxic effects in vertebrates. In this context, the antigenotoxic effect of aqueous Bryoria capillaris (Ach.) extract (BCE) was studied against the genotoxic damage induced by IMA on cultured human lymphocytes using chromosomal aberrations (CA) and micronucleus (MN) as cytogenetic parameters. Human peripheral lymphocytes were treated in vitro with varying concentrations of BCE (5, 10, 25, 50 and 100 µg/mL), tested in combination with IMA (336 µg/mL). BCE alone was not genotoxic, and when combined with IMA treatment, it reduced the frequency of CAs and the rates of MN. A clear dose-dependent decrease in the genotoxic damage of IMA was observed, suggesting a genoprotective role of BCE. The results of the present study suggest that this plant extract per se do not have genotoxic potential, but can modulate the genotoxicity of IMA on peripheral human lymphocytes in vitro. In conclusion, our findings may have an important application in the protection of cultured human lymphocyte from the genetic damage and side effects induced by agricultural and medical chemicals that are hazardous to people.
