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. Cryptogamie Algolologie 16 3: The Hague, The Netherlands. These molecules have different degree of sulfate in their structure and therefore are capable of substitute heparin Farias et al.

Occurrence of heparin in the invertebrate Styela plicata Tunicata is restricted to cell layers facing the outside environment. The mixture was homogenized in a Waring blender, centrifuged at x g for 15 minutes and supernatant filtered through 0.

A delay in clot formation less than two minutes was observed in prothrombin time test for this species from Chlorophyta: Thrombosis is a health problem that affects many people in the world.

We can concluded that these species can be considered as potentially alternative source of anticoagulant molecules.

Pharmacological activities casacda marine algae. Biochimica et Biophysica Acta Finally, sample collected in April of change the anticoagulant activity been active only in the thrombin time test. An International Journal in Haemostasis and Thrombosis 16 4: Studies on anticoagulant-active arabinan sulfates form the green alga, Codium latum.

Thrombosis Research 55 3: Niveles elevados de factor XI han sido implicados en casos de trombosisaunque es incierto que es lo que determina cascaea niveles, y cuan severo puede ser el estado procoagulante.

It has been done research in anticoagulant activity of polysaccharides and glycosaminoglycans of diverse sources such as: Inhibition of thrombin by sulfated polysaccharides isolated from green algae.

Similar results of slightly anticoagulant potency were observed but in thrombin time test for C. Rhamnan sulfate from cell walls of Monostroma latissimum. The results showed other algae with slightly inhibition of clot formation activity, it is not common to consider this species for further investigation, nevertheless the retardation of formation of clot by Penicillus capitatusa species evolutionary related to Halimeda genus Vroom et al. American Journal of Clinical Pathology Biochemical and Biophysical Research Communications 2: Highly sulfated dermatan sulfates from ascidians.

However we consider more research has to be done, focused to this topic, in order to probe this hypothesis. Heparin, a sulphated glycosaminoglycan wide used in oral anticoagulant therapy, was used as reference in both proofs.

This work deals with the detection of anticoagulant activity in macroalgae from several localities along the Mexican Atlantic coast. Journal of Molecular Biology 2: Anticoagulant activity, marine algae, Gulf of Mexico, heparin.

The extract of L. Propiedades anticoagulantes de extractos de algas marinas mexicanas: De Wikipedia, la enciclopedia libre. Results for algal extracts in both anticoagulant tests are in table ed. Forty nine species were tested, 14 from Chlorophyta, 8 from Phaeophyta and 27 belonging to Rhodophyta. 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 coagulacon observed the double anticoagulant action in sample collected in May ofbut six months later Novembersame specie only was active in the prothrombin time test.

El factor IXa, por otro lado, activa al factor X.

Further data on the structure of brown seaweed fucans: Anticoagulant activity in extracts of British marine algae. Revista de la Sociedad Mexicana de Historia Natural We considered that algal extracts have substances capable of inhibit clot formation in the last steps of the coagulation cascade.
