[Various structural-functional characteristics of erythrocyte membranes in malignant growths].

Changes in the acetylcholinesterase activity, thermal and osmotic stability of erythrocyte membranes of the cancer patients are found as compared with this activity of erythrocyte membranes of donors. No differences were detected in the rate of phosphate anion transfer through the erythrocyte membranes in the examined persons. The data obtained show that the development of malignant tumours is followed by the changes in the structural and functional state of surface components of erythrocyte membranes.
