Concentration-Dependent Protection by Ethanol Extract of Propolis against γ-Ray-Induced Chromosome Damage in Human Blood Lymphocytes

Figure 1

Chromosome aberrations in human lymphocytes exposed to 2 Gy of gamma radiation and different conditions: only in the presence of 250  L of the ethanol (without EEP), with a concentration of 1000  g mL-1 of EEP added just after the irradiation, without any treatment, concentration 0, and with increasing concentrations of EEP (from 20 to 2000  g mL-1) added before irradiation. (*) Concentrations with values significantly different from the results obtained in the blood irradiated without any treatment.
