“…russelii) , a venomous snake of the Indian subcontinent, contains an intricate blend of various biologically active protein families. Consumptive coagulopathy is one of the most manifested systemic pathological condition observed in viper envenomated victims [ 8 ]. The procoagulant venom proteins like RVV-X and RVV-V activators accelerate the blood coagulation cascade and the simultaneous down regulation of activated protein C causes severe depletion of the coagulation factors thereby depriving the victim of the serine proteases shortly [ 8 ].…”

“…Consumptive coagulopathy is one of the most manifested systemic pathological condition observed in viper envenomated victims [ 8 ]. The procoagulant venom proteins like RVV-X and RVV-V activators accelerate the blood coagulation cascade and the simultaneous down regulation of activated protein C causes severe depletion of the coagulation factors thereby depriving the victim of the serine proteases shortly [ 8 ]. This scenario is further worsened by the anticoagulant and haemorrhagic components like phospholipase A 2 (PLA 2 ) enzymes, L-amino acid oxidase (LAAO) and metalloproteases leading to hypovolemic shock and even death [ 9 ].…”

“…A maioria dos inibidores das proteínas plasmáticas, dos fatores da coagulação e do sistema complemento são sintetizados no fígado, podendo ser encontrados no plasma e no veneno das serpentes (CIDADE et al, 2006;CHENG et al, 2012;LU;MEJIA , 2010;EARL et al, 2012;KINI, 2005;IWANAGA, 1972;SUZUKI, 1974). O fígado nas serpentes se situa ao longo do esôfago, estendendo-se do coração ao piloro, onde alcança o pâncreas.…”

“…Inibidores de serinoproteases foram isolados dos venenos de serpentes da família Viperidae e Elapidae (FILIPPOVICH et al, 2002;GUO et al, 2001;WU;LO, 1983;LI;GREENAWAY, 2006;RITONJA;TURK;GUBENSEK, 1983;ZAIDI;JÖRNVALL, 1990a;SHAFQAT et al, 1990b;SCHWEITZ et al, 1994) os quais são em grande parte inibidores de serinoproteases pertencentes à família de inibidores de tripsina pancreática bovina tipo Kunitz (BPTI) (CHENG et al, 2012;LASKOWSKI, 1986;LASKOWSKI;KATO, 1980 O estudo de inibidores de proteases no plasma de serpentes pode levar ao desenvolvimento de novas alternativas terapêuticas para uma variedade de doenças (DE MORAIS et al, 2009;EARL et al, 2012;OLIVEIRA et al, 2008;OLIVEIRA et al, 2011;SANTOS-FILHO et al, 2011;SOARES et al, 2003;ZHANG et al, 2001;ZHANG et al, 2007). Portanto, faz-se necessário a identificação de moléculas do fígado para entender o processo de inibição de toxinas por proteínas do plasma de B. jararaca.…”
