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 ...

We studied the ability of the polyvalent antivenom produced in Costa Rica to neutralize lethal, hemorrhagic, edema-forming, proteolytic, hemolytic, hyaluronidase and fibrinolytic activities of the venoms of Bothrops asper ...

Se establecen las condiciones óptimas para la determinación comparativa de la actividad proteolítica de los venenos de serpientes costarricenses sobre la caseína y se describe dicha actividad para 13 venenos diferentes. ...

As a tribute to Revista de Biología Tropical in its 50th anniversary, this review describes some of the main research efforts carried out in the study of the chemical composition and the mechanism of action of toxins present ...

The development of antibody response against phospholipase A activity of Bothrops asper venom was studied in a group of adult and healthy horses used in the production ofthe polyvalent antivenom at the Instituto Clodomiro ...

Biochemically and pharmacologically, myotoxins isolated from snake venoms can be placed in four main groups: myolaxic phospholipases A, low molecular weight basic toxins, cardiotoxins, and hemorrhagic myotoxins. The myotoxic ...

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. ...

The time-course and composition of inflammatory infiltrate in mouse gastrocnemius injected with Bothrops asper venom was studied. The venom induced myonecrosis, and a prominent decrease in muscle levels of creatine kinase ...

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 ...
