Introduction Thrombosis is a health problem that affects many people in the world. We considered that extracts who acted on both path-ways of extrinscea formation, affect the cascade of coagulation in the point of convergence, that is in transformation of fibrinogen to fibrin. The extracts could act preventing the conversion of prothrombin to thrombin, also they could act stopping the transformation of fibrinogen to convert intrineeca to fibrin o even in the polymerization of this last molecule.

Comparative Biochemistry and Physiology B: We collected algal material along the central coast of Veracruz, and some localities of Campeche, Yucatan and Quintana Roo States in order to have samples of the coast of the Atlantic Ocean in Mexico Gulf cooagulacion Mexico and Caribbean sea.

SPB Academic Publishing bv. However we consider more research has to be done, focused to this topic, in order to probe this hypothesis.

Neutralisation of Factor Xa interrupts the blood coagulation cascade and inhibits both coagullacion formation and thrombus development. It limits thrombin formation by inactivating factors Va and VIIIa, thereby providing negative feedback regulation of coagulation. We considered that algal extracts have substances capable coagulacoon inhibit clot formation in the last steps of the coagulation cascade. The results showed that four species presented potent anticoagulant activity same as heparin in the two pathways: This last molecule is a sulfated glicosaminoglycan used in oral therapy for anticoagulant disorders.

Caulerpa paspaloides Chlorophyta fue activa solamente en el tiempo de trombina. The mixture was homogenized in a Waring blender, centrifuged at x g for 15 minutes and supernatant filtered through 0.

Similar results of slightly anticoagulant potency were observed but in thrombin time test for C. Propiedades anticoagulantes de extractos de algas marinas mexicanas: This is the first report of anticoagulant activity in Anadyomene stellataLobophora variegata and Liagora farinosa. A total of five species were active in standard clotting test, three of Chlorophyta, one from Phaeophyta and one from Rhodophyta.

Epiphytes were removed carefully from the algae under the microscope to avoid contamination.

Structure and anticoagulant activity of a fucosylated chondroitin sulfate from echinoderm. Alternatively is possible that algal substances acted impeding the polymerization of fibrin for clot formation. In the body, protein C controls the generation of thrombin extrrinseca, one of the substances factors involved in blood clotting.

A delay in clot formation less than two minutes was observed in prothrombin time test for this species from Chlorophyta: Occurrence of heparin in the invertebrate Styela plicata Tunicata is restricted to cell layers facing the outside environment. Forty nine species extribseca tested, 14 from Chlorophyta, 8 from Phaeophyta and 27 belonging to Rhodophyta. Results for algal extracts in both anticoagulant tests are in table 1. These variation has been suggested as been influenced by geographical factors such as climate and locality and has been probed with primary metabolites as lectins by Ingram and Fabregas et cogaulacion.
