Biochemistry and toxicology of toxins purified from the venom of the snake Bothrops asper
The isolation and study of individual snake venom components paves the way for a deeper understanding of the pathophysiology of envenomings – thus potentially contributing to improved therapeutic modalities in the clinical ...
Evaluation of antivenoms in the neutralization of hyperalgesia and edema induced by Bothrops jararaca and Bothrops asper snake venoms
Neutralization of hyperalgesia induced by Bothrops jararaca and B. asper venoms was studied in rats using bothropic antivenom produced at Instituto Butantan (AVIB, 1 ml neutralizes 5 mg B. jararaca venom) and polyvalent ...
Toxicity of Bothrops sp snake venoms from Ecuador and preclinical assessment of the neutralizing efficacy of a polyspecific antivenom from Costa Rica
The toxicological profile of the venoms of the snakes Bothrops asper and Bothrops atrox from Ecuador was investigated, together with the venom of a population of B. asper formerly classified as ‘Bothrops xanthogrammus’. ...
Pharmacological modulation of hyperalgesia induced by Bothrops asper (terciopelo) snake venom
The ability of Bothrops asper snake venom to cause hyperalgesia was investigated in rats, using the paw pressure test. Intraplantar injection of the venom (5–15 μg/paw) caused a dose and time-related hyperalgesia, which ...
Ontogenetic variability of Bothrops atrox and Bothrops asper snake venoms from Colombia
The lancehead snakes Bothrops asper and Bothrops atrox inflict 70–90% of the 3000 bites reported every year in Colombia. In this work, the venoms of B. atrox from Meta (Villavicencio, 33 specimens) and B. asper from Antioquia ...
Purification and characterization of BaH4, a hemorrhagic metalloproteinase from the venom of the snake Bothrops asper
A hemorrhagic metalloproteinase, named BaH4, was isolated from the venom of the snake Bothrops asper by a combination of ion-exchange chromatography on DEAE-Sepharose and gel filtration on Sephacryl S-200. BaH4 is a 69 kDa ...
