ABSTRACT
Study on the peroxidation of membrane lipid and the change of some anti-oxidant enzymes during the storage of erythrocytes by additive system. The invitro study was conducted with two additive systems: one is the AS-T which is the first preparation in VN and the other is the preparation of Terumo, a leading company of the world on the blood preparations. The results demonstrate that the two systems are equally in the anti-peroxidation activation of membrance lipid. The ability to maintain enzyme activation of Superoxyd dismutase (SOD) and Gluathion peroxidase (GCH-Px) of erythrocytes during of storage process (from ) to 35 days), the erythrocyte mass which is preserved by AST solution abilize activity of SOD and GSH-Px better than by Terumo solution, with this result os signficant slower increasing of MDA concentration at the end of storage
