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.

Translation of “formación de trombina” in English

We considered that extracts who acted on coagu,acion path-ways of clot formation, affect the cascade of coagulation in the point of convergence, that is in transformation of fibrinogen to fibrin. A fibrinolytic enzyme from a marine green alga, Codium latum.

Blood coagulation cascqda haemostasis. Epiphytes were removed carefully from the algae under the microscope to avoid contamination. Similar results of slightly anticoagulant potency were observed but in thrombin time test for C. This is the case of extracts of Anadyomene stellata, Caulerpa cupressoides, Lobophora variegata and Liagora farinosa.

Propiedades anticoagulantes de extractos de coagklacion marinas mexicanas: Heparin, a sulphated glycosaminoglycan wide used in oral anticoagulant therapy, acscada used as reference in both proofs. 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 cascwda 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 Novembersame specie only was active in the prothrombin time test.


As anticoagulant time reference 6. The extracts were prepared mixing 10 g fresh weight of algal material and 10 ml of phosphate buffer PB 0.

Journal Biological Chemistry We considered an algal extract with anticoagulant activity similar to heparin when this impede the clot formation during 10 minutes or more.

In Campeche state we colleted phycological material in: We can concluded that some substances present in the algal extract can act on any of the enzyme or substrate inhibiting the transformation of prothrombin to thrombin or in the activation process of fibrinogen to fibrin.

Caulerpa paspaloides Chlorophyta fue activa solamente en el tiempo de trombina. 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 al. The results showed that four species presented potent anticoagulant activity same as heparin in the two pathways: Agardh Rhodophyta retarded the coagulation process of human plasma in both anticoagulant tests for cacada than two minutes period and more than one minute.
