Antigenotoxic Properties ofAgaricus blazeiagainst Hydrogen Peroxide in Human Peripheral Blood Cells
The ability ofAgaricus blazeimushroom in its dried and powdered mycelial form was evaluated for its antigenotoxic properties for the first time. Antigenotoxic effects in human peripheral blood cells against H2O2-induced DNA damage were examined in pretreatment and posttreatment protocol by comet assay. The results showed better antigenotoxic properties ofAgaricus blazeion the interventional level, respectively, after treatment.Agaricus blazeiin concentration of 250 μg/mL after treatment was most efficient in regard to its action against DNA damage. The evaluation of repair kinetics showed decrease in H2O2induced DNA damage 15 min after the application ofA. blazei, reaching the maximum potency after 30 min. Analysis of antioxidant properties ofAgaricus blazeirevealed strongOH•scavenging properties and moderate reducing power, while its DPPH scavenging ability was weak. In regard to our findings, we can conclude that our preliminary results demonstrated antigenotoxic properties ofAgaricus blazeiand its strongOH•scavenging ability. Mechanisms underlying its properties should be further evaluated in in vivo studies.
