Abstract
We investigated the antithrombotic properties of the EVAL membrane for use in the artificial kidney and obtained the following finding. (1) The proteins deposited on the EVAL membrane surface at the initial stage of dialysis was mainly albumin and globulin. The composition of the deposited proteins remained unchanged 4 to hours after the start of reqular dialysis. The other membranes, however, allowed more deposition of fibrinogen than albumin and globulin. (2) In the blood passing test using healthy blood, the EVAL membrane provoked less activation of platelet factors such as β-TG and PF-4 as well as of blood coagulation factors than the other membranes.
