ABSTRACT
An aggregation of erythrocytes in autologous plasma after blood storage for 14 days at 4 °C was studied using photometry and light microscopy. The decrease of ATP content, the formation of echinocytes and spheroechinocytes, the decrease of rouleaux form of erythrocyte aggregation were observed during the storage. On the other hand the aggregates of echinocytes were formed in the stored blood. The addition of plasma from the fresh blood didn't restore the normal discocytic shape and aggregation of erythrocytes in the stored blood. The possible mechanisms of erythrocytes and echinocytes aggregation are discussed.

The effect of adenosine on the shape, aggregate morphology and aggregability of ATP-depleted erythrocytes was studied. It is shown that the ATP-depletion of erythrocyte leads to the change in their shape: diskocytes transform to echinocytes. It is found that the aggregability of such cells in autoplasma significantly decreased. Incubation of echinocytes with adenosine largely restored discoid shape and erythrocyte aggregability.
