ESTRADA, E. et al. Preliminar study of the effects of gamma radiations on human red blood cells. An. AFA [online]. 2020, vol.31, n.2, pp.51-54. ISSN 0327-358X.

In this study, the alterations in viscoelastic and aggregation parameters of red blood cells were analyzed for usual gamma irradiation procedures for transfusion purposes. In order to determine possible hemorheological changes that may affect the health of patients and their relationship with the biochemical changes observed, the blood samples were irradiated at different doses. The results show alterations in the erythrocyte aggregation time, in the membrane surface viscosity and in the size of the aggregates in the irradiated samples, suggesting that the damage produced by the ionizing radiation affects the physical properties of red blood cell membrane at different levels.

Palavras-chave : erythrocyte; gamma radiation; viscoelasticity.
