Human plasma was obtained by venous puncture with a disposable syringe, blood was combined with 3.

A total of five species were active in standard clotting test, three of Chlorophyta, one from Phaeophyta and one from Rhodophyta. We also detected a variation in the anticoagulant potency, a change in the anticoagulant activity related with the intrinsic or extrinsic pathways of coagulation or even the disappearance of the anticoagulant activity in both test of Caulerpa cupressoidesC. Pharmacological activities of marine algae.

Heparin, a sulphated glycosaminoglycan wide used in oral anticoagulant therapy, was used as reference in both proofs. Journal of Applied Phycology Cada cadena posee una masa molecular de aproximadamente 80 We considered that algal extracts have substances capable of inhibit clot formation in the last steps of the coagulation cascade.

Anticoagulant activity in extracts of British marine algae. Forty nine seaweed species collected off shore of several localities of Gulf of Mexico and Cascaea Caribbean sea were screened in order to detect anticoagulant activity in both intrinsic and extrinsic pathways of clot formation. Journal of Thrombosis and Haemostasis: The samples for this study were manually collected from the seven localities described above, from the Gulf of Mexico and Mexican Caribbean sea during May to October figure 1were classified by genus and transported frozen to the laboratory using solid CO 2.
