(A) Elongation index (EI) at different shear stress values (Pa). Red blood cells were exposed to 100 mM d-Gal for 24 h, with or without pre-incubation with 10 µg/mL Açaì extract for 1 h. ° = p < 0.05 versus 100 mM d-Gal; n = 3. (B) Evaluation of RBC morphology. Representative images obtained using scanning electron microscopy show RBCs with normal biconcave form (control) and with flattened shape (leptocytes, arrows) (100 mM d-Gal). Açaì extract (10 µg/mL) pre-incubation attenuated the shape changes compared to 100 mM d-Gal treatment. Magnification 3000×. Images reported from reference cited above.
