Highly sulfated dermatan sulfates from ascidians. Caulerpa paspaloides Chlorophyta was active only in the thrombin time test. Studies on anticoagulant-active arabinan sulfates form the green alga, Codium latum.

Further data on the structure of brown seaweed fucans: This oa the case of extracts of Anadyomene stellata, Caulerpa cupressoides, Lobophora variegata and Liagora farinosa. Bases de datos de enzimas.

Seasonal variation of antibacterial and antifungal activities of the extracts of marine algae from southern coasts of India. It has been reported also that brown algae have a potent anticoagulant activity in fucoidans Chevolot et al. Archivado desde el original el 16 de abril de Cada cadena posee una masa molecular de aproximadamente 80 Developments in Comparative Immunology 9: The mixture was homogenized in a Waring blender, centrifuged at x g for 15 minutes and supernatant filtered through 0.


American Journal of Clinical Pathology Results Results for algal extracts in both anticoagulant tests are in table 1. However we consider more research has to be done, focused to this topic, in order to probe this hypothesis. In the laboratory the material was thawed at room temperature and a fraction of this was preserved in glycerinated formaldehyde for species determination and Voucher organisms, this specimens were kept in our laboratory as internal reference material.

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 of Mexico and Caribbean sea. Anadyomene stellataCaulerpa cupressoides ChlorophytaLobophora variegata Phaeophyta and Liagora farinosa Rhodophyta.

Cladistics of the Bryopsidales: Se concluye que estas especies pueden ser consideradas como una fuente alternativa de nuevos anticoagulantes. A fibrinolytic enzyme from a marine green alga, Codium latum.

On the quantitative estimation of prothrombin. Forty nine species were tested, 14 from Chlorophyta, 8 from Phaeophyta and 27 belonging to Rhodophyta. Occurrence of heparin in the invertebrate Styela plicata Tunicata is restricted to cell layers facing the outside environment.

The Hague, The Netherlands.

Finally, sample collected in April of change the anticoagulant activity been active only in the thrombin time test. Recently, a group of scientists had stand out the potentiality of some proteins and proteoglycans capable of interfere with blood clotting cascade, particularly from Codium Matsubara et al. Materials and methods 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.


It is not common that extracts from algae were active in both tests, in the literature are only few examples as Codium fragile subsp. Thrombosis is a health problem that affects many people in the world.

Current views on blood coagulation and haemostatic mechanism. 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. Introduction to Applied Phycology.

Introduction Thrombosis is a health problem that affects many people in intrinsecq world. Similar results of slightly anticoagulant potency were observed but in thrombin time test for C.
