(1989)En el presente trabajo se investigó el efecto del suero antiofídico polivalente, producido en Costa Rica, sobre la actividad hemolítica (CH50) del complemento sérico humano (in vitro) y de conejo (in vitro e in vivo). ... -
Efectos de la oxitetraciclina en un sistema de biopurificación: eliminación de triazinas y organofosforados y variación en la expresión de genes de degradación
(2020)La contaminación que provoca el mal uso de agroquímicos y el manejo inadecuado de sus desechos, puede afectar cuerpos de agua superficiales o subterráneos y grandes volúmenes de suelo. Los plaguicidas organofosforados y ... -
Efectos locales en el envenenamiento ofídico en América Latina
(2003)Los envenenamientos por mordedura de serpiente constituyen un importante problema de salud pública en América Latina. La gran mayoría de estos envenenamientos son causados por mordeduras de serpientes de la familia Viperidae, ... -
Effect of a recombinant Lys49 PLA2 myotoxin and Lys49 PLA2-derived synthetic peptides from Agkistrodon species on membrane permeability to water.
(2004)The aim of this work was to study the effect of recombinant ACL myotoxin, a Lys49PLA2 from Agkistrodon contortrix laticinctus snake venom and Lys49PLA2-derived synthetic peptides corresponding to the region 115–129 of ... -
Effect of adjuvants on the antibody response of mice to Bothrops asper (Terciopelo) snake venom
(1996)The adjuvant properties of several immunostimulant molecules on the murine antibody response to Bothrops asper snake venom were evaluated. Mice receiving venom together with either sodium alginate, calcium alginate, aluminum ... -
Effect of Bothrops asper (Fer-De-Lance) snake venom on erythrocyte membrane. A comparative study
(1992-02)1. The effect of Bothrops asper venom on erythrocytes of different species, sheep erythrocyte ghost vesicles and liposomes made of phospholipids from sheep erythrocytes was studied. 2. B. asper venom had a direct hemolytic ... -
Effect of calcineurin inhibitors on myotoxic activity of crotoxin and Bothrops asper phospholipase A2 myotoxins in vivo and in vitro
(2006-07)Previous studies have shown that calcineurin activity plays a critical role in the myotoxic activity induced by crotoxin (CTX), a group II phospholipase A2 (PLA2) with neurotoxic and myotoxic actions. In order to address ... -
Effect of geographical variation of Echis ocellatus, Naja nigricollis and Bitis arietans venoms on their neutralization by homologous and heterologous antivenoms
(2015-12-15)Two antivenoms prepared by using Echis ocellatus, Bitis arietans and Naja nigricollis venoms from different locations in sub-Saharan Africa were compared for their neutralizing ability. Both antivenoms were similarly ... -
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 ... -
Effect of storage temperature on the stability of polyvalent antivenom produced in Costa Rica.
(1990)The effect of storage temperature on the stability of the liquid polyvalent (crotaline) antivenom produced at the Instituto Clodomiro Picado, Costa Rica, was studied during a twelve-month period. The following parameters ... -
Effect of the metalloproteinase inhibitor batimastat in the systemic toxicity induced by Bothrops asper snake venom: understanding the role of metalloproteinases in envenomation
(2014-03-15)The peptidomimetic hydroxamate metalloproteinase inhibitor batimastat (BB-94) was assessed for its ability to neutralize the systemic effects (lethality, hemorrhage and coagulopathy) induced by the venom of Bothrops asper, ... -
Effect of various Viperidae and Crotalidae snake venoms on endothelial cells in vitro
(1994)The effect of various crotalid and viperid venoms at 10, 50 and 100 μg/ml was examined on bovine and murine endothelial cells in vitro. The venoms caused the cells to lose their processes, leading to the appearance of ... -
Effectiveness of batimastat, a synthetic inhibitor of matrix metalloproteinases, in neutralizing local tissue damage induced by BaP1, a hemorrhagic metalloproteinase from the venom of the snake Bothrops asper
(2000-07-15)Batimastat (BB-94), a synthetic hydroxamate peptidomimetic matrix metalloproteinase inhibitor, was tested for its ability to inhibit proteolytic and toxic effects induced by BaP1, a 24-kDa hemorrhagic metalloproteinase ... -
Effects of a myotoxic phospholipase A2 isolated from Bothrops asper venom on skeletal muscle sarcoplasmic reticulum
(1987)The myotoxin from B. asper snake venom inhibited Ca-ATPase activity of rabbit sarcoplasmic reticulum after incubation in vitro. Inhibition was non-competitive and albumin enhanced the effect of the toxin. Furthermore, B. ... -
