Title in Portuguese
Estudo comparativo do veneno botrópico de referência em relação ao veneno das serpentes Bothrops jararaca nascidas em cativeiro no Laboratório de Herpetologia do Instituto Butantan.
Keywords in Portuguese
Bothrops jararaca
Comparação
Plante
Soro antibotrópico
Veneno botrópico de referência nacional
Veneno de serpente
Abstract in Portuguese
Em 1987 o Instituto Nacional de Controle de Qualidade em Saúde iniciou o uso do Veneno Botrópico de Referência Nacional (VBRN), que é a primeira extração das serpentes B. jararaca recém-chegadas da natureza. Em 10 anos notou-se uma queda de 67,65% na recepção de serpentes ao Instituto Butantan (IB), e na distribuição geográfica, resultando em uma maior heterogeneidade na composição do VBRN. Assim, comparamos os venenos das serpentes nascidas em cativeiro (VP) do Laboratório de Herpetologia do IB com o VBRN, para verificar a possibilidade de incorporar o VP na preparação dos lotes do VBRN. O VP mostrou-se estatisticamente semelhante ao VBRN nos testes de dosagem de proteínas, SDS-PAGE, 2DE, cromatografia, atividade fosfolipásica, ELISA, Western blotting, dose mínima coagulante (plasma) e hemorrágica, enquanto para as atividades de L-aminoácido oxidase, caseinolítica, zimografia e dose mínima coagulante (fibrinogênio) o VP mostrou-se diferente do VBRN. Para as doses letais e efetiva dos venenos o pool do VP com VBRN foi mais eficaz do que os VP e o VBRN sozinhos.

Abstract in English
In 1987, The National Institute of Quality Control in Health in Brazil (INCQS) established the Brazilian Reference Bothrops Venoms (BRBV), which should be composed of the first extractions of newcomers wild snakes. In 10 years there has been a decrease of 67.65% in the reception snakes to Butantan Institute (IB), and geographic distribution, resulting in a higher heterogeneity in BRBV composition. So, we compared the venom samples of snakes born in captivity (SVP) of IB Herpetology Laboratory with BRBV to check the possibility of incorporating the SVP in the preparation of batches of BRBV. SVP was statistically similar to BRBV the proteins dosage, SDS-PAGE, 2DE, chromatography, phospholipase, ELISA, Western blotting, minimum coagulant dose (plasma) and hemorrhage dose, while for L-amino acid oxidase activity, caseinolytic, zymography and minimum coagulant dose (fibrinogen) SVP was shown to be different from BRBV. For effective and lethal doses of pool with SVP and BRBV it was more effective than SVP and BRBV alone.
