[Changes in the structural-functional state of erythrocyte membranes treated with anion transport inhibitors].
Effect of 4,4-dyisotiocyanostilben-2,2-disulfonate (DIDS) and 1-ftor-2,4-dinitrobenzol (NDFB) on the rate of phosphate ion transport in erythrocytes, filtrability and thermal stability of erythrocytes and on the structural state of the erythrocyte membrane estimated by UV-fluorescence, PAAG--electrophoresis and measuring of the activity of membrane-bound acetylcholinesterase (AChE) has been studied. Unpenetrating anion transport inhibitor DIDS is shown to induce structural modifications of bands 3 of protein and AChE, while DNFB penetrating the membrane causes a significant reorganization of many membrane proteins (including spectrin) resulting in changes of transport and mechanical properties of erythrocytes.
