AB  - The aim of this study was to investigate radioprotective properties of Echinacea purpurea tablets in vivo. We analysed lymphocyte chromosome aberrations (CA), micronuclei (MN), apoptosis of leukocytes and haematological parameters in a group of radiation workers who were identified as carrying dicentric chromosomes in their lymphocytes. All radiation workers were taking two 275 mg Echinacea tablets b.i.d., according to a pharmacists recommendation. All parameters were analysed before and after the two-week treatment. At the end of the treatment lymphocyte CA frequency dropped significantly, and the number of apoptotic cells increased. The inverse lymphocyte-to-granulocyte ratio at the beginning of the study changed to normal at its end. In conclusion, biological effects observed after administration of Echinacea purpurea preparation suggest that it may be beneficial for the prevention of adverse health effects in workers exposed to ionising radiation.

AB  - Fanconi anemia (FA) is a genetic disease characterized by progressive pancytopenia and cancer susceptibility. The clinical and cellular phenotypes of Fanconi anemia are associated with a set of redox abnormalities, indicating that FA is an oxidative stress-related disorder. Fanconi anemia cells are highly sensitive to DNA clastogen agents, but their response to ionizing radiation is still unclear. The aim of this study was to evaluate the in vitro radiosensitivity of Fanconi anemia homozygotes and heterozygotes, and to assess the contribution of catalase and superoxide dismutase (SOD) to the overall radiobiological response of the cells. The incidence of radiation-induced lymphocyte micronuclei was used as the indicator of radiation sensitivity in vitro, whereas the activity of antioxidant enzymes was determined in erythrocytes. Patients with FA exhibited a two-fold decrease in catalase activity, accompanied by lowered activity of SOD, and increased incidence of baseline micronuclei. In the entire group of patients (with one exception), a reduced yield of radiation-induced micronuclei in lymphocytes was observed, and this was categorized as a radioresistant response. A mild radioresistant in vitro response was also observed in carrier-mothers, accompanied by reduced activity of catalase. The radiosensitivity of carrier-fathers was normal. The results of this study suggest that reduced activity of catalase is an important contributor to the radiobiological response of cells.
