Summary: | This work evaluated the effect of in vitro and in vivo treatment with ASA on the morphology of the red blood cells. Blood samples or Wistar rats were treated with ASA for one hour. Blood samples or animals treated with saline were used as control group. Blood smears were prepared, fixed, stained and the qualitative and quantitative morphology of red blood cells were evaluated under optical microscopy. Data showed that the in vitro treatment for one hour with ASA at higher dose used significantly (p<0.05) modified the perimeter/area ratio of the red blood cells. No morphological alterations were obtained with the in vivo treatment. ASA use at highest doses could interfere on shape of red blood cells.
Este trabalho avaliou o efeito do tratamento in vitro e in vivo com AAS na morfologia dos eritrócitos. Amostras de sangue ou ratos Wistar foram tratadas com AAS por uma hora. Amostras sangüíneas ou animais tratados com salina foram utilizados como grupos controle. Distensões de sangue foram preparadas, fixadas, coradas e a análise morfológica qualitativa e quantitativa dos eritrócitos foi realizada em microscópio óptico. Os dados mostraram que o tratamento in vitro por uma hora com AAS na maior dose utilizada modificou significativamente (p<0.05) a relação perímetro/área dos eritrócitos. Não foram obtidas alterações morfológicas com o tratamento in vivo. O uso do AAS em doses altas poderia interferir na forma dos eritrócitos. |
