title: [Changes in the deformability of erythrocytes and 2,3-DPG in coronary artery stenosis].
abstract: The changes of deformability of RBC and 2,3-DPG in RBC in patients with coronary artery stenosis and the influence of some factors on them were studied. The results showed that: (1) the deformability index was inversely proportional to the degree of lesions of coronary vessels (P less than 0.01); (2) the 2,3-DPG was inversely proportional to the degree of lesions of coronary vessels (P less than 0.01); (3) there was a significant decrease in deformability index after using contrast medium; (4) Saliva may increase deformability of RBC and 2,3-DPG; (5) Nifedipine may increase deformability of RBC. These results showed: (1) the possible existence of microcirculatory dysfunction in coronary artery disease and in parallel of impaired deformability of RBC; (2) the possibility of normalization of the decreased deformability of 2,3-DPG in RBC by Salvia; (3) the possibility of increase of velocity of blood flow in microcirculation in coronary artery disease by Salvia.
