Factor VIII

The research effort has been focused on one genus, forgotten the basic detection of different algae as a potential source of alternative anticoagulant molecules. Structure and anticoagulant activity of cascadda galactans.

Introduction Thrombosis is a health problem that affects many people in the world. Similar results were detected in Caulerpa cupressoides extracts collected in three occasions, in this case even the total absence of activity was detected in one sample.

It is relevant to point out the dependence of anticoagulant potency due to the locality where algae grows, also the date of collection and thus, the climate season is other factor that could influence the synthesis of compounds, particularly in the brown alga Lobophora variegata we observed the double anticoagulant action in sample collected in May ofbut six months later November cadcada, same specie only was active in the prothrombin time test.

A delay in clot formation less than two minutes was observed in prothrombin time test for this species from Chlorophyta: Results Results for algal extracts in both anticoagulant tests are in table 1.


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 extrinsecw the coast of the Atlantic Ocean in Mexico Gulf of Mexico and Caribbean sea.

APC exerts its effect by the inactivation of the activated forms of factors V and VIII which leads to a decrease in thrombin formation. Alternatively is possible that algal substances acted impeding the polymerization of fibrin for clot formation. Structure of a fucose-branched chondroitin sulfate from sea cucumber. This last molecule is a sulfated glicosaminoglycan used in oral therapy for anticoagulant disorders.

This is the first report of anticoagulant activity in Anadyomene stellataLobophora variegata and Liagora farinosa. Heparin, a sulphated glycosaminoglycan wide used in oral anticoagulant therapy, was used as reference in both proofs. Anadyomene stellataCaulerpa cupressoides ChlorophytaLobophora variegata Phaeophyta y Liagora farinosa Rhodophyta.

Journal of Applied Phycology Thrombosis is a health problem that affects many people in the world. Our results showed four species with similar activity susceptible of further research for isolation and characterizations of active substances. American Journal of Clinical Pathology Se concluye que intrknseca especies pueden ser consideradas como una fuente alternativa de nuevos anticoagulantes. This is the case of extracts of Anadyomene stellata, Caulerpa cupressoides, Lobophora variegata and Liagora farinosa.

CASCADA DE COAGULACION by mitzy sabrina rodriguez anaya on Prezi

Anticoagulant, fibrinolytic and antiaggregant activity of carrageenans and alginic acid. The extracts of Anadyomene stellata Wulfen C.

Propiedades anticoagulantes de extractos de algas marinas mexicanas: These examples may contain colloquial words based on your search. An anticoagulant proteoglycan from the marine green alga, Codium pugni-formis. Anticoagulant and antithrombin activities of oversulfated fucans.

formación de trombina – Translation into English – examples Spanish | Reverso Context

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.

Journal of Clinical Pathology 6: Biological activity of extracts from some Mediterranean macrophytes. British Phycological Journal The Hague, The Netherlands.

We can suggest these four species as a sources of new anticoagulant substances. The extracts could act preventing the conversion of dee to thrombin, also they could act stopping the transformation of fibrinogen to convert it to fibrin o even in the polymerization of this last molecule.

The discovery of alternative anticoagulant molecules must be an important task for scientists.
