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 ...
N-Formyl-Perosamine Surface Homopolysaccharides Hinder the Recognition of Brucella abortus by Mouse Neutrophils
(2016-06)
Brucella abortus is an intracellular pathogen of monocytes, macrophages, dendritic cells, and placental trophoblasts. This bacterium
causes a chronic disease in bovines and in humans. In these hosts, the bacterium also ...
Isolation from a polyvalent antivenom of antibodies to a myotoxin in Bothrops asper snake venom
(1985)
Antibodies against Bothrops asper rmyotoxin were purified from a polyvalent antivenom by affinity chromatography . These antibodies neutralized most of the myotoxic activity of crude B. asper venom, as judged by histologic ...
Neutralization of myotoxic phospholipases A2 from the venom of the snake Bothrops asper by monoclonal antibodies
(1992)
The neutralization of two myotoxic phospholipases A2 from the venom of Bothrops asper, myotoxins I and II, by two murine monoclonal antibodies is reported. The monoclonal antibodies, MAb-3 and Mab-4, recognize different ...
Immunohistochemical demonstration of the binding of bothrops asper myotoxin to skeletal muscle sarcolemma
(1987)
The binding of Bothrops asper myotoxin to mouse skeletal muscle was studied at both the light and electron microscope levels using the peroxidase anti-peroxidase technique. The toxin binds to muscle cell sarcolemma, and ...

A new muscle damaging toxin, myotoxin II, from the venom of the snake Bothrops asper (terciopelo)
(1989)
A new muscle damaging toxin, myotoxin II, was purified from the venom of Bothrops asper by ion-exchange chromatography on CMSephadex C-25. The toxin is a dimeric, basic protein with a monomer mol.wt of 13,341, according ...
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) ...
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). ...
