Local effects induced by coral snake venoms: Evidence of myonecrosis after experimental inoculations of venoms from five species
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 ...
Dissociation of enzymatic and toxic activities by the use of antibodies
Disociación de las actividades enzimáticas y tóxicas mediante la utilización de anticuerpos
IN A RECENT article KASTURi and GOWDA,(1990) described the dissociation of enzymatic and toxic activities of phospholipases A, (PLA) from Vipera russelli venom by neutraliza- tion experiments u ...
Quantitation by enzyme-immunoassay of antibodies against Bothrops myotoxins in four commercially-available antivenoms
An enzyme-immunoassay (EIA) for the quantitation of antibodies against myotoxins present in the venoms of Bothrops asper (Costa Rica), B. atrox (Colombia) and B. moojeni (Brazil), was developed. This EIA was utilized for ...
Myotoxin II from Bothrops asper (Terciopelo) venom is a lysine-49 phospholipase A2
A basic, dimeric myotoxic protein, myotoxin II, purified from Bothrops asper venom has a similar molecular weight and is immunologically cross-reactive with antibodies raised to previously isolated B. asper phospholipases ...
Local tissue damage induced by Bothrops snake venoms - A review
This review focuses on the local effects induced by Bothrops venoms. These envenomation are characterized by myonecrosis, hemorrhage and edema which develop rapidly after venom inoculation. Myonecrosis is caused (a) directly, ...
The Phospholipase A2 Homologues of Snake Venoms: Biological Activities and Their Possible Adaptive Roles
A particular subgroup of toxins with phospholipase A2 (PLA2) structure, but devoid of this enzymatic activity, is commonly found in the venoms of snakes of the family Viperidae, and known as the PLA2 homologues. Among ...
Effects of Bothrops asper snake venom on lymphatic vessels: insights into a hidden aspect of envenomation
(PlosOne 2(10):e318, 2008-10-15)
Background: Envenomations by the snake Bothrops asper represent a serious medical problem in Central America and parts of South America. These envenomations concur with drastic local tissue pathology, including a prominent ...
Isolation and characterization of four medium-size disintegrins from the venoms of Central American viperid snakes of the genera Atropoides, Bothrops, Cerrophidion and Crotalus
Four disintegrins were isolated from the venoms of the Central American viperid snakes Atropoides mexicanus (atropoimin), Bothrops asper (bothrasperin), Cerrophidion sasai (sasaimin), and Crotalus simus (simusmin). ...
Evaluación de la capacidad de cuatro antivenenos comerciales para neutralizar el veneno de la serpiente Bothrops asper (terciopelo) de Costa Rica
We studied the ability of four commercially available antivenoms to neutralize several toxic and enzymatic activities of Bothrops asper (terciopelo) venom from Costa Rica. Experiments with preincubation of venom and antivenom ...
