GIANI, Tania S. et al. Assessment of effects of a formula used in the traditional Chinese medicine (Buzhong Yi Qi Wan) on the morphologic and osmotic fragility of red blood cells. Rev. bras. farmacogn. [online]. 2007, vol.17, n.4, pp. 501-507. ISSN 1981-528X. http://dx.doi.org/10.1590/S0102-695X2007000400005.
Buzhong Yi Qi Wan (BYQW) is a combination of some medicinal herbs widely used in traditional Chinese medicine to treat blood, spleen and stomach disorders. Morphometric analysis and osmotic fragility assay have been used to evaluate changes on membrane integrity of red blood cells. The aim of this work was to evaluate the effect of an aqueous BYQW extract on the morphology and osmotic fragility of red blood cells. Blood samples were treated with BYQW extract, quantitative/qualitative morphological analysis and osmotic fragility assay were carried out against control groups treated with saline. The data obtained indicated no modification on morphology but osmotic fragility assay suggested a significant (p<0.05) increasing of hemolysis in red blood cells isolated from blood treated with aqueous BYQW extract. In conclusion, the aqueous BYQW extract could affect the membrane integrity decreasing the osmotic resistance but without altering the shape of red blood cells.
