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 ...
Isolation of a myotoxin from Bothrops asper venom: Partial characterization and action on skeletal muscle
(1984)
A myotoxic phospholipase has been isolated from Bothrops asper venom by ion-exchange chromatography on CM-Sephadex followed by gel filtration on Sephadex G-75. The toxin is a basic polypeptide with an estimated molecular ...
A new muscle damaging toxin, myotoxin II, from the venom of the snake Bothrops asper (terciopelo)
(1989)
A new muscle damaging toxin, myotoxin II, was purified from the venom of Bothrops asper by ion-exchange chromatography on CMSephadex C-25. The toxin is a dimeric, basic protein with a monomer mol.wt of 13,341, according ...
Neutralization of local effects of the terciopelo (Bothrops asper) venom by blood serum of the colubrid snake Clelia clelia
(1982)
The neutralizing capacity of the blood serum of the non-venomous snake Clelia clelia against the hemorrhagic, edematous and myonecrotic effects of Bothrops asper venom in white mice was tested using in vitro preincubation ...
Cleavage of the NH2-Terminal Octapeptide of Bothrops asper Myotoxic Lysine-49 Phospholipase A2 Reduces Its Membrane-Destabilizing Effect
(1994-08)
Bothrops asper myotoxin II was cleaved with cyanogen bromide to determine the role of NH2-terminal amino acid residues in its ability to destabilize negatively charged liposomes and to induce myonecrosis. After treatment, ...
Pathological alterations induced by neuwiedase, a metalloproteinase isolated from Bothrops neuwiedi snake venom
(2001-06)
The pathological alterations induced by neuwiedase, a 22 kDa class P-I metalloproteinase from the venom of the South American pit viper Bothrops neuwiedi, were studied in mice. Neuwiedase was devoid of hemorrhagic activity ...
Snake venom metalloproteinases: Their role in the pathogenesis of local tissue damage
(2000-09-10)
The biochemical characteristics of hemorrhagic metalloproteinases isolated from snake venoms are reviewed, together with their role in the pathogenesis of the local tissue damage characteristic of crotaline and viperine ...
Isolation of basic myotoxins from Bothrops Moojeni and Bothrops Atrox snake venoms
(1990)
Three myotoxins, one from the venom of Bothrops atrox and two from the venom of B. moojeni, were isolated by ion-exchange chromatography on CM-Sephadex C-25. The three toxins are basic proteins with an estimated mol. wt ...
Inhibition of toxic activities of Bothrops asper venom and other crotalid snake venoms by a novel neutralizing mixture
(1997-12)
The majority of snake bites in Central America are caused by Bothrops asper, whose venom induce complex local effects such as myonecrosis, edema and especially hemorrhage. These effects are only partially neutralized by ...
Structural and functional characterization of myotoxin I, a Lys49 phospholipase A2 homologue from the venom of the snake Bothrops atrox
(2004-07)
A new myotoxin was isolated from the venom of Bothrops atrox from Colombia. B. atrox myotoxin I is a homodimer, with a subunit molecular mass of 13,826, and a pI of 8.9. Its complete nucleotide sequence was obtained by ...
