[Influence of intravenous injection of fucoidan from brown seaweed Fucus evanescens by plasma rabbits anticoagulant activity and neutralisation by sulphate protamin of fucoidans antithrombin activity in vitro].

With fucoidan from Fucus evanescens dose increase from 1 to 5 mg/kg plasma coagulation time in test A(see symbol)TB increases. Sulphate protamin in final concentration 0.67-1.35 mkg/ml will neutralise antithrombin activity of fucoidans from brown seaweed Fucus evanescens and Laminaria cichorioides. The gravimetrichesky relation for the investigated samples makes an antidot/anticoagulant 1.
