Comparative study on coagulant, defibrinating, fibrinolytic and fibrinogenolytic activities of Costa Rican crotaline snake venoms and their neutralization by a polyvalent antivenom
(1989)
The coagulant, defibrinating, fibrino lytic and fibrinogenolytic activities of venoms from ten species of Costa Rican crotaline snakes were studied, together with the neutralization of these effects by a polyvalent antivenom. ...
Biochemical and pharmacological similarities between the venoms of newborn Crotalus durissus durissus and adult Crotalus durissus terrificus rattlesnakes
(1991)
A comparative study was performed with the venoms of newborn Crotalus durissus durissus, adult Crotalus durissus terrificus and adult Crotalus durissus durissus snakes. Venom of newborn specimens of C.d. durissus is very ...
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, ...
Instituto Clodomiro Picado: Ciencia y Tecnología Endógenas en la Solución de un Problema de la Salud Pública en Centroamérica
(1999-05)
El accidente ofídico re-presenta un importante problema de salud pública en Centroamérica. En Costa Rica, por ejemplo, ocurren alrededor de 600 mordeduras por serpientes en humanos anualmente (Gutiérrez, 1995), en tanto ...
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 ...
Isolation of a galactose-binding lectin from the venom of the snake Bothrops godmani (Godmann's pit viper).
(1990)
A galactose-binding
lectin, isolated from the venom of B. gotlmani by affinity chromatography . is
an acidic protein (pI 4.9) with a subunit mol. wt of about 14,000, occurring
mostly as a disulfide-linked dimer of 28,000. ...
Experimental myonecrosis induced by the venoms of South American Micrurus (coral snakes)
(1992)
Venoms from 11 taxa of Micrurus (coral snakes) from Brazil and Colombia were tested for myotoxic activity in mice. All venoms, except that of M. surinamensis, induced myotoxicity as judged by the increase in plasma creatine ...
Effect of Preservatives on IgG Aggregation, Complement-activating Effect and Hypotensive Activity of Horse Polyvalent Antivenom Used in Snakebite Envenomation
(2002-06)
Intravenous administration of antivenoms is associated with early adverse reactions in a number of cases, but the causes of this phenomenon are still unclear. The effect of preservatives (phenol and thimerosal) on IgG ...
Neutralization of four Peruvian Bothrops sp. snake venoms by polyvalent antivenoms produced in Perú and Costa Rica: preclinical assessment
(2005-06)
Envenomations after bites inflicted by snakes of the genus Bothrops constitute a public health hazard in Perú, and the intravenous administration of equine-derived antivenoms represents the only scientifically validated ...
Efficacy and safety of two whole IgG polyvalent antivenoms, refined by caprylic acid fractionation with or without β-propiolactone, in the treatment of Bothrops asper bites in Colombia
(2006-12)
The efficacy and safety of two whole IgG polyvalent antivenoms (A and B) were compared in a randomised, blinded clinical trial in 67 patients systemically envenomed by Bothrops asper in Colombia. Both antivenoms were ...
