[Characteristics of the action of an acidic sulfated polysaccharide on global blood coagulation in vitro. Preliminary study in various species of mammals and in man].
An acid sulphated polysaccharide, isolated from a red marine seaweed, Asparagopsis armata ( Harv .), increases the coagulation time of the plasma in vitro studies. This property, compared with the anticoagulant activity of pentosan polysulphate and heparin, pr esents , with concentration and temperature, some variations in man and other mammals . The rat and human plasma seem to behave in the same way with this substance.
