AVALIAÇÃO DA ATIVIDADE NÃO CITOTÓXICA DO VENENO DE BOTHROPS JARARACUSSU EM CÉLULAS MONONUCLEARES DO SANGUE PERIFÉRICO

Abstract

Snake venoms are biological resources of great pharmaceutical value. Besides presenting a small number of antiviral drugs, a large amount of pathogens develop mechanisms which escape from the action of the drugs, thus causing the growth of resistance. It was demonstrated that biomolecules contained in venoms have high therapeutic values which could be used as antimicrobial agents. The objective of this research is to evaluate the non cytotoxic activity which was isolated from the venom of Bothrops jararacussu in peripheral blood mononuclear cells. In this research, mononuclear cells were separated from healthy donors. After the activation of the cells with phytohemagglutinin and interleukin-2, different concentrations of the poison were added in order to evaluate its non cytotoxic activity. The concentration of the venom at 0.05 mg/mL showed no cytotoxicity, but at 5 and 0.5 mg/mL it was cytotoxic. Our study opens the way to further researches which aim to identify the antimicrobial activities of crude venoms and their fractions.
