Resumo: 	The aim of this work was to evaluate the effect of fenoprofen on the labeling of blood constituents with technetium-99m, on the morphology of red blood cells and on the plasmid DNA. Blood samples from Wistar rats were incubated with fenoprofen and the assay of labeling of blood constituents with technetium-99m (99mTc) was performed. Blood cells, plasma, soluble and insoluble fractions of blood cells and plasma were separated. The radioactivity in each fraction was counted and percentage of incorporated radioactivity (%ATI) was determined. Blood smears were prepared, fixed, stained and the qualitative and quantitative morphology of the red blood cells (RBC) was evaluated. Plasmid (pBSK) was incubated with fenoprofen with stannous chloride, and agarose gel electrophoresis procedure was carried out to evaluate genotoxic and the protection of this drug against stannous chloride effect on DNA. In conclusion, under the conditions used in this work, our data suggest that fenoprofen would not (i) affect the fixation of the 99mTc on the blood constituents, (ii) alter the RBC membrane and (iii) present genotoxic and redox effects.
