Estudio comparativo de venenos de ejemplares recien nacidos y adultos de Bothrops asper
(1980)
Se estudiaron comparativamente los venenos de ejemplares recién nacidas (menos de un mes de edad) y adultas de Bothrops asper de dos regiones costarricenses: San Carlos en la vertiente atlántica y Puriscal en la pacífica. ...
Estudio comparativo de los venenos de serpiente Cascabel (Crotalus durissus durissus) de ejemplares adultos y recien nacidos
(1983)
Venoms from adult and newborn Central American rattlesnakes (Crotalus durissus durissus) were compared for lethal, proteolytic, hemorrhagic, myonecrotic, edematigenous and in vitro hemolytic activities. Electrophoretic and ...
Comparative study of the edema-forming activity of Costa Rican snake venoms and its neutralization by a polyvalent antivenom
(1986)
The edema-forming activity of eight Costa Rican crotaline snake venoms and its neutralization by a polyvalent antivenom were studied using the mouse footpad test. All of the venoms induced edema, the highest activity being ...
Efectos proteolitico, hemorragico y mionecrotico de los venenos de serpientes costarricenses de los generos Bothrops, Crotalus y Lachesis
(1980)
We studied the proteolytic, hemorrhagic and myonecrotic activities of ten Costa Rican species of snakes from the family Viperidae. All of them showed these three activities but we did not observe any correlation between ...
Estudios cariológicos de cinco especies de serpientes costarricenses de la familia colubridae
(1984)
The karyotypes of five species of colubrid snakes from Costa Rica are as follows: Imuntodes cenchao and Drymobius margaritiferus have a diploid number of 36, with 16 macro- and 20 microchromosomes. The fourth pair is ...
Pharmacological activities of a toxic phospholipase A isolated from the venom of the snake Bothrops asper
(1986)
A toxic phospholipase A was isolated from the venom of Bothrops asper. It induced skeletal muscle damage, anticoagulant effects and edema in the foot pad. The toxin had an intravenous LD50 of 95 micrograms/16-18 g mouse ...
Mionecrosis, hemorragia y edema inducidos por el veneno de Bothrops asper en ratón blanco
(1980)
Pathogenesis of the myonecrotic, hemorrhagic and edema-forming effects in white mice inoculated with Bothrops asper venom was studied at different time intervals by means of light microscopy, determination of serum levels ...
Pathogenesis of myonecrosis induced by crude venom and a myotoxin of Bothrops asper.
(1984)
The pathogenesis of skeletal muscle necrosis induced by crude Bothrops asper venom and isolated myotoxic phospholipase was studied using light and electron microscopy. White mice were injected intramuscularly with a dose ...
Skeletal muscle regeneration after myonecrosis induced by crude venom and a myotoxin from the snake Bothrops asper (Fer-de-Lance).
(1984)
Skeletal muscle regeneration was studied following injections of Bothrops asper venom and a myotoxin isolated from the crude venom. In toxin-injected muscle regeneration proceeded normally. By 4 days there were myotubes ...
Polimorfismo cromosómico intraespecífico en la serpiente de coral Micrurus nigrocinctus (Ophidia: Elapidae)
(1981)
En un estudio cito genético de 59 ejemplares de la serpiente de coral Micrurus nigrocinctus procedentes de todas las áreas de distribución de Costa Rica, se observó dos patrones cariológicos principales: I o "nigrocinctus" ...
