Abstract

CANAS BERMUDEZ, Omaira; ROJAS, Diego Andrés  and  ARBELAEZ RAMIREZ, Luis Fernando. Determining Human Clot Lysis Time (in vitro) with Plasminogen/Plasmin from Four Species (Human, Bovine, Goat, and Swine): humano, bovino, caprino e suíno. Rev. Med. Vet. [online]. 2015, n.29, pp.11-22. ISSN 0122-9354.

Cardiovascular disease is the leading cause of death worldwide, including failures in the plasminogen/plasmin system which is an important factor in poor lysis of blood clots. This article studies the fibrinolytic system in four species of mammals, and it identifies human plasminogen with highest thrombolysis efficiency. It examines plasminogen from four species (human, bovine, goat, and swine) and identifies the most efficient one in human clot lysis in vitro. All plasminogens were identically purified by affinity chromatography. Human fibrinogen was purified by fractionation with ethanol. The purification of both plasminogen and fibrinogen was characterized by one-dimensional SDS-PAGE (10%). Human clot formation in vitro and its dissolution by plasminogen/plasmin consisted of determining lysis time from clot formation to its dilution. Purification of proteins showed greater than 95% purity, human plasminogen showed greater ability to lyse clot than animal plasminogen. The article concludes that human plasminogen/plasmin has the greatest catalysis and efficiency, as it dissolves human clot up to three times faster than that of irrational species.

Keywords : plasminogen; plasmin; thrombin; tissue plasminogen activator; lysis.
