Abstract

In this study, the anticoagulation effect of glycosaminoglycan from Mactra veneriformis was studied. The results showed that glycosaminoglycan mainly exerted anticoagulation via antithrombin III. Glycosaminoglycan could passivate the function of heparin cofactor II inhibiting thrombin activity. Glycosaminoglycan significantly reduced the activities of coagulation factor II, V, VII, X, VIII, IX, XI, XII as well as fibrinogen content in the plasma (p<0.05, p<0.01). Besides, glycosaminoglycan could extend blood recalcification time in rats by shielding Ca²⁺ in plasma and significantly reduced Ca²⁺ concentration in rats and mice serum (p<0.05, p<0.01). Glycosaminoglycan reduced the Ca2+ concentration in serum in a more intensive way than that of heparin sodium (p<0.05, p<0.01).
