Abstract
A dextrorotatory polysaccaride recently isolated from whale lung and intestine has been demonstrated to have a high anticoagulant activity. in vitro and in vivo. Protamine neutralization and lipolytic activities are similar to those of beef heparin. The sulfur content of the new polysaccharide is lower than that of beef heparin. The new substance was used successfully as an anticoagulant in 221 dog perfusion experiments.
