Heterologous fibrin sealant derived from snake venom: from bench to bedside – a...
Ferreira Jr,Rui Seabra; Barros,Luciana Curtolo de; Abbade,Luciana Patrícia Fernandes; Barraviera,Silvia Regina Catharino SartoriAbstract Hemostatic and adhesive agents date back to World War II, when homologous fibrin sealant came onto scene. Considering that infectious diseases can be transmitted via human blood, a new heterologous fibrin sealant was standardized in the 1990s. Its components were a serine protease (a thrombin-like enzyme) extracted from the venom of Crotalus durissus terrificus snakes and a fibrinogen-rich cryoprecipit...

Oliveira,Laudicéia Alves de; Ferreira Jr,Rui Seabra; Barraviera,Benedito; Carvalho,Francilene Capel Tavares de; Barros,Luciana Curtolo deAbstract Background Classically, Crotalus durissus terrificus (Cdt) venom can be described, according to chromatographic criteria, as a simple venom, composed of four major toxins, namely: gyroxin, crotamine, crotoxin and convulxin. Crotoxin is a non-covalent heterodimeric neurotoxin constituted of two subunits: an active phospholipase A2 and a chaperone protein, termed crotapotin. This molecule is composed of ...
