Comparative study on the ability of IgG and Fab sheep antivenoms to neutralize local hemorrhage, edema and myonecrosis induced by Bothrops asper (terciopelo) snake venom
(2000-02)
The ability of sheep antivenoms, consisting of whole IgG molecules or Fab fragments, to neutralize local hemorrhage, edema and myonecrosis induced by Bothrops asper venom was comparatively studied in mice. The two antivenoms ...
Cálculo de la actividad hemolítica del complemento sérico (CH50) mediante un programa en "BASIC": Comparación con el método gráfico manual.
(1986)
En el presente trabajo se describe el programa para el cálculo de la actividad hemolítica del complemento sérico, y se muestran los resultados de un estudio comparativo entre el método gráfico manual y el método matemático ...
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 ...
Pathogenesis of myonecrosis induced by coral snake (Micrurus nigrocinctus) venom in mice
(1986-02)
The mode by which coral snake (Micrurus nigrocinctus) venom affects skeletal muscle was studied using a combined approach. The venom induced early functional and structural alterations in the plasma membrane of muscle ...
Venenos de serpiente: de la investigación al tratamiento
Snake venoms: from research to treatment
(Acta méd. costarric, Vol. 54 (2), abril-junio, 2012, 2012)
El presente trabajo ofrece una breve visión de cómo se ha enfrentado el problema del ofidismo en Costa Rica, y en especial, de cómo la investigación científica y tecnológica ha contribuido a tal fin. Se resumen los orígenes ...
Determinación cuantitativa de la actividad lítica del complemento sérico (CH50) en adultos costarricenses
(1986)
En el presente trabajo se estandariza un método
simple y cuantitativo para la determinación de la
actividad hemolítica (CH5O) del complemento sérico.
Con este método, se evalúa los niveles de
complemento en una muestra ...
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. ...
Snake Venomics and Antivenomics of the Arboreal Neotropical Pitvipers Bothriechis lateralis and Bothriechis schlegelii
(2008-04-30)
We report the comparative proteomic characterization of the venoms of two related neotropical arboreal pitvipers from Costa Rica of the genus Bothriechis, B. lateralis (side-striped palm pit viper) and B. schlegelii (eyelash ...
Local effects induced by coral snake venoms: Evidence of myonecrosis after experimental inoculations of venoms from five species
(1983)
The local effects induced by intramuscular inoculations of venons from six species of coral snakes were studied in mice. Venoms of Micrurus nlgrocinctus nigrocinctus, M. n . moquitensis, M. alleni, M. frontalis, M. aarinkauda ...
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 ...
