| Outline of Final Research Achievements |
When erythrocytes are suspended in a plasma or other macromolecular solutions, they form face-to-face aggregates called rouleaux, which are easily broken up by mechanical shearing. It has been pointed out that enhanced erythrocyte aggregation affects in vivo blood flow. There are two models for erythrocyte aggregation: the bridging model and the depletion model. The bridging model assumes the adsorption of macromolecules onto the erythrocyte membranes. On the other hand, the depletion model assumes the osmotic attractive forces due to macromolecular depletion near the erythrocyte surface. In this study, the interaction between erythrocytes and fibrinogen molecules was measured by quartz crystal microbalance. The results suggested that erythrocyte aggregation was caused by the mechanism of macromolecular bridging.
