[Factor XIII activity in the presence of suppression of the function of the anticoagulant system and its restoration in animals on an atherogenic ration].

With depressed function of the anticoagulation system in rats produced by their long-term maintenance on an atherogenic ration a rising fibrin-stabilizing activity of the XIII factor, by comparison with that in healthy animals and pertinent controls, is observed. A protracted administration to the animals with depressed function of the anticoagulation system of the compound "Linetol", that contains ethers of unsaturated fatty acids, given together with vitamin "A" results in a drastic fall of the factor XIII activity in the blood plasma with continued maintenance on the atherogenic diet.
