Evaluation of the Effect of p -Tyrosol on the Level of DNA Damage in the DNA Comet Assay In Vivo

The effect of p- tyrosol on the spontaneous level of DNA damage in the cells of the bone marrow, liver, kidney, and rectum of mice (series I) and on the genotoxic effects of cytostatic drugs with different mechanisms of action in rat testicular cells (series II) was studied by DNA comet assay on C57BL/6 mice. p- Tyrosol was administered in a dose of 40 mg/kg once (series I) or for 5 days before and 5 days after cytostatic exposure (busulfan, paclitaxel, methotrexate; series II). It was found that p- tyrosol reduced spontaneous level of DNA damage in all studied organs. p- Tyrosol exhibited an antigenotoxic effect with respect to the DNA-damaging action of methotrexate and produced no genoprotective effect in case of busulfan and paclitaxel.
