[Interaction of liposomes with erythrocytes in the process of their lysis]

Interaction of phosphatidyl choline liposomes with erythrocytes during spontaneous lysis of the latter has been studied. It is shown that hemoglobin which is released during the lysis of erythrocytes is found by liposomes which in their turn are absorbed on the external erythrocyte surface. In this case the binding of hemoglobin by liposomes takes place with a greater speed than its release during erythrocyte lysis and is accompanied by a change in its conformation. Possibilities of the microcalorimetry methods for studying the interaction of liposomes with erythrocytes under the conditions mentioned above are considered.
