Comparison between IgG and F(ab′)2 polyvalent antivenoms: neutralization of systemic effects induced by Bothrops asper venom in mice, extravasation to muscle tissue, and potential for induction of adverse reactions
(2001-06)
Whole IgG and F(ab′)2 equine-derived polyvalent (Crotalinae) antivenoms, prepared from the same batch of hyperimmune plasma, were compared in terms of neutralization of the lethal and defibrinating activities induced by ...
Cambios en el patrón electroforético del veneno de cascabela muda (Lachesis muta stenophrys) durante el almacenamiento bajo diferentes condiciones
(1985)
Liquid and lyophilized samples of Lachesis muta venom were stored at different temperatures and for different periods of time, and analyzed by polyacrylamide gel electrophoresis (PAGE) and immunoelectrophoresis. Only slight ...
Hyperalgesia induced by Asp49 and Lys49 phospholipases A2 from Bothrops asper snake venom: pharmacological mediation and molecular determinants
(2003-05)
The ability of Lys49 and Asp49 phospholipases A2 (PLA2), from Bothrops asper snake venom, to cause hyperalgesia was investigated in rats, using the paw pressure test. Intraplantar injection of both toxins (5–20 μg/paw) ...
Niveles de inmunoglobulinas séricas (IgG, IgA e IgM) en adultos jóvenes sanos, por el método de inmunodifusión radial
(1985)
Se determinó la concentración de IgG, IgA, e IgM en el suero de 49 estudiantes universitarios normales, de 18 a 25 años. Para esto se empleó el método de inmunodifusión radial, en placas comerciales. Los resultados fueron ...
Efecto del suero antiofídico sobre la actividad hemolítica del complemento humano (in vitro) y de conejo (in vitro e in vivo).
(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). ...
The C-terminal region of a Lys49 myotoxin mediates Ca2þ influx in C2C12 myotubes
(2010-02)
Myotoxins are abundant components of snake venoms, being a significant public health problem worldwide. Among them, Lys49 phospholipase A2 homologue myotoxins cause extensive necrosis in skeletal muscle tissue. Their ...
p-Bromophenacyl bromide modification of Bothrops asper myotoxin II, a lysine-49 phospholipase A2, affects its pharmacological activities
(1993-09)
Modification of Bothrops asper myotoxin II, a lysine-49 phospholipase A2 variant, was carried out with p-bromophenacyl bromide. Modified toxin did not show changes in its charge and immunological properties but two of its ...
Venom of the Coral Snake Micrurus clarki: Proteomic Profile, Toxicity, Immunological Cross-Neutralization, and Characterization of a Three-Finger Toxin
(2016)
Micrurus clarki is an uncommon coral snake distributed from the Southeastern Pacific of Costa Rica to Western Colombia, for which no information on its venom could be found in the literature. Using a 'venomics' approach, ...
Lemnitoxin, the major component of Micrurus lemniscatus coral snake venom, is a myotoxic and pro-inflammatory phospholipase A2
(2016-08-26)
The venom of Micrurus lemniscatus, a coral snake of wide geographical distribution in South America, was fractionated by reverse-phase HPLC and the fractions screened for phospholipase A2 (PLA2) activity. The major component ...
Characterization of a novel snake venom component: Kazal-type inhibitor-like protein from the arboreal pitviper Bothriechis schlegelii
(2016-06)
Snake venoms are composed mainly of a mixture of proteins and peptides. Notably, all snake venom toxins have been assigned to a small number of protein families. Proteomic studies on snake venoms have recently identified ...
