Unresolved issues in the understanding of the pathogenesis of local tissue damage induced by snake venoms
(2018-06)
Snakebite envenoming by viperid species, and by some elapids, is characterized by a complex pattern of
tissue damage at the anatomical site of venom injection. In severe cases, tissue destruction may be so
extensive as ...
Activity of hemorrhagic metalloproteinase BaH-1 and myotoxin II from Bothrops asper snake venom on capillary endothelial cells in vitro
(1994-04)
In vivo, hemorrhagic toxins isolated from snake venoms cause a disorganization of the basal lamina of capillaries, with a concomitant degenerative process of endothelial cells. In this study we investigated the effects of ...
Ontogenetic changes in the venom of the snake Lachesis muta stenophrys (bushmaster) from Costa Rica
(1990)
A comparative study was performed on some enzymatic and toxic activities of venoms collected from newborn, one-year old, two-years old and adult (more than five-years old) specimens of Lachesis muta stenophrys. There was ...
Venom of the crotaline snake Atropoides nummifer (jumping viper) from Guatemala and Honduras: comparative toxicological characterization, isolation of a myotoxic phospholipase A(2) homologue and neutralization by two antivenoms
(2001-07)
A comparative study was performed on the venoms of the crotaline snake Atropoides nummifer from Guatemala and Honduras. SDS-polyacrylamide gel electrophoresis, under reducing conditions, revealed a highly similar pattern ...
Immunoglobulin G and F(ab')2 polyvalent antivenoms do not differ in their ability to neutralize hemorrhage, edema and myonecrosis induced by Bothrops asper (terciopelo) snake venom
(1997-11)
The ability of whole immunoglobulin G (IgG) and F(ab')2 polyvalent (Crotalinae) antivenoms to neutralize the hemorrhagic, edema-forming and myotoxic activities of Bothrops asper venom was studied. Both antivenoms were ...
Trends in Snakebite Envenomation Therapy: Scientific, Technological and Public Health Considerations
(2007)
The therapy of snakebite envenomation has been based on the parenteral administration of animal-derived antivenoms. Despite the success of this treatment at reducing the impact of snakebite mortality and morbidity, mostly ...
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 ...
Local tissue damage induced by Bothrops snake venoms - A review
(1989-12)
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, ...
