Selecting key toxins for focused development of elapid snake antivenoms and inhibitors guided by a Toxicity Score
(2015-09-15)
For more than 100 years, antivenoms have been produced by traditional methods of immunization of large mammals with mixtures of snake venoms (World Health Organization, 2010 and Gutiérrez et al., 2011). With the introduction ...
Quantitation by enzyme-immunoassay of antibodies against Bothrops myotoxins in four commercially-available antivenoms
(1991)
An enzyme-immunoassay (EIA) for the quantitation of antibodies against myotoxins present in the venoms of Bothrops asper (Costa Rica), B. atrox (Colombia) and B. moojeni (Brazil), was developed. This EIA was utilized for ...
Neutralization of coral snake Micrurus nigrocinctus venom by a monovalent antivenom
(1991)
The neutralizing ability of a monovalent anti-Micrurus nigrocinctus (coral snake) antivenom produced in Costa Rica was tested against the lethal, myotoxic and phospholipase A2 activities of homologous venom. In addition, ...
Comparative study of the edema-forming activity of Costa Rican snake venoms and its neutralization by a polyvalent antivenom
(1986)
The edema-forming activity of eight Costa Rican crotaline snake venoms and its neutralization by a polyvalent antivenom were studied using the mouse footpad test. All of the venoms induced edema, the highest activity being ...
Venom of the crotaline snake Atropoides nummifer (jumping viper) from Guatemala and Honduras: comparative toxicological characterization, isolation of a myotoxic phospholipase A(2) homologue and neutralization by two antivenoms
(2001-07)
A comparative study was performed on the venoms of the crotaline snake Atropoides nummifer from Guatemala and Honduras. SDS-polyacrylamide gel electrophoresis, under reducing conditions, revealed a highly similar pattern ...
Pharmacokinetic-pharmacodynamic relationships of immunoglobulin therapy for envenomation.
(2003-07)
Parenteral administration of horse- and sheep-derived antivenoms constitutes the cornerstone in the therapy of envenomations induced by animal bites and stings. Depending on the type of neutralising molecule, antivenoms ...
Immunoglobulin G and F(ab')2 polyvalent antivenoms do not differ in their ability to neutralize hemorrhage, edema and myonecrosis induced by Bothrops asper (terciopelo) snake venom
(1997-11)
The ability of whole immunoglobulin G (IgG) and F(ab')2 polyvalent (Crotalinae) antivenoms to neutralize the hemorrhagic, edema-forming and myotoxic activities of Bothrops asper venom was studied. Both antivenoms were ...
Antibody neutralization of a myotoxin from the venom of Bothrops asper (terciopelo)
(1987)
Neutralization of biological activities of B. asper myotoxin by a monospecific anti-myotoxin rabbit serum and polyvalent antivenom was studied. Both antisera neutralized myotoxic, phospholipase A and lethal activities of ...
Histopathological and biochemical alterations induced by intramuscular injection of Bothrops asper (terciopelo) venom in mice
(1989)
The local and systemic pathological changes induced by an i.m. injection of 100 micrograms of Bothrops asper venom in mice were studied histologically and by following the changes in serum levels of enzymes, proteins, ATP ...
Neutralization of local tissue damage induced by Bothrops asper (terciopelo) snake venom
(1998-11)
Local tissue damage represents a serious consequence of Bothrops asper envenomations. It encompasses a complex series of alterations, including myonecrosis, dermonecrosis, hemorrhage and edema. Due to its rapid development ...
