Body distribution of Bothrops asper (terciopelo) snake venom myotoxin and its relationship to pathological changes
(1988)
The distribution of 125I-labelled Bothrops asper myotoxin following i.m. and i.v. injections was studied in mice. After i.m. administration the toxin was concentrated in the injected gastrocnemius muscle, with relatively ...
Cariotipos de diez especies de serpientes costarricenses de la familia Viperidae
(1979)
All the karyotypes of ten snake species of the family Viperidae from Costa Rica have a diploid number of 36 chromosomes, 16 macro- and 20 microchromosomes; females show an heteromorphism in the fourth pair. The karyological ...
Cariotipos de las principales serpientes coral (Elapidae: Micrurus) de Costa Rica
(1979)
Se describen los cariotipos de las tres especies de serpientes de coral (Elapidae: Micrurus) más abundantes en Costa Rica: M. nigrocinctus, M. alleni y M. mipartitus. M. nigrocinctus presenta dos poblaciones cariotípicas ...
Mecanismo de acción de miotoxinas aisladas de venenos de serpientes
(1984)
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 ...

In this paper we describe the karyotype of the yellow-bellied sea snake, Pelamis platurus from Costa Rica. The diploid number is 38 chromosomes, with 20 macrochromosomes and 18 microchromosomes. The pairs 1 and 2 are ...
Neutralization of proteolytic and hemorrhagic activities of Costa Rican snake venoms by a polyvalent antivenom
(1985)
The polyvalent antivenom produced at the Instituto Clodomiro Picado, Costa Rica, was tested for its capacity to neutralize proteolytic and hemorrhagic activities of ten Costa Rican crotaline venoms. In experiments with ...
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 ...
