Experiments on animals in vitro showed that phosphatidylserine-containing anticoagulant (PhCA) inhibited factors X and VIII, restricted factor V activity and, to a less degree, that of factor VII, decreased the activity of fibrin-stabilizing factor, the degree of clot retraction and its tolerance to fibrinolysin. The activity of factor IX remained virtually unchanged under the influence of PhCA, whereas the contact phase was speeded up by 14%. Anticoagulant activity of PhCA was accounted for by the phosphatidyl molecule residue - glycerylphosphorylserine.
