title: [Effect of the critical fragmentation of erythrocyte membranes].
abstract: After sonification of erythrocyte membranes, some changes were registered in these including a loss of their ability to structural rearrangements caused by cAMP (ESR-spectroscopy and luminescence data), an increase in cAMP binding and aggregation of intramembrane particles (freeze-fracture data). These findings suggest a non-identity of the structural organization in membranes and in their fragments. The cooperative nature of membrane structural modification at ultrasonic fragmentation is shown.
