Pharmacological study of edema induced by venom of the snake Bothrops asper (terciopelo) in mice
(1995-01)
The effect of several drugs on the edema-forming activity of Bothrops asper venom was studied plethysmographically using the mouse foot pad assay. Bothrops asper venom induced a dose-dependent edema which developed rapidly ...
Myonecrosis induced in mice by a basic myotoxin isolated from the venom of the snake Bothrops nummifer (jumping viper) from Costa Rica
(1989)
The mode of action of a basic myotoxin isolated from Bothrops nummifer venom was studied. This myotoxin is a basic polypeptide of 13,000 mol.wt, with a high content of lysine and aspartate, as well as of hydrophobic amino ...
Anticomplementary Activity of Horse IgG and F(ab’)2 Antivenoms
(2014)
Envenomation by poisonous animals is a neglected condition according to the World Health Organization (WHO). Antivenoms are included in the WHO Essential Medicines List. It has been assumed that immunoglobulin G (IgG) ...
Biochemical and biological characterization of Ecuadorian pitviper venoms (genera Bothriechis, Bothriopsis, Bothrops and Lachesis)
(1996-06)
The lethality and enzymatic activities of venoms from six Ecuadorian pitvipers (Bothriechis schlegelii, Bothriopsis punctata, Bothriopsis taeniata, Bothrops asper, Bothrops atrox and Lachesis muta) are similar to those of ...
In vitro activity of BaH1, the main hemorrhagic toxin of Bothrops asper snake venom on bovine endothelial cells
(1995-10)
Incubation of BaH1, the main hemorrhagic toxin purified from the venom of Bothrops asper, with endothelial cells caused the appearance of spaces among the cells. This effect became more noticeable with increasing hemorrhagin ...
Crystallization and preliminary diffraction data of two myotoxins isolated from the venoms of Bothrops asper (Terciopelo) and Bothrops nummifer (jumping viper)
(1993-08)
Two myotoxins isolated from B. asper (myotoxin II) and B. nummifer (myotoxin I) snake venoms have been crystallized and their diffraction properties are described. These myotoxins are phospholipase A2 variants which lack ...
Increments in serum cytokine and nitric oxide levels in mice injected with Bothrops asper and Bothrops jararaca snake venoms
(2000-09)
Changes in serum levels of several cytokines and nitric oxide were studied in BALB/c mice injected intraperitoneally with one median lethal dose (LD(50)) of the venoms of Bothrops asper and Bothrops jararaca, two of the ...
Pathological changes induced by BaH1, a hemorrhagic proteinase isolated from Bothrops asper (Terciopelo) snake venom, on mouse capillary blood vessels
(1994-08)
The pathological changes induced in capillaries by BaH1, a hemorrhagic metalloproteinase isolated from the venom of Bothrops asper, were studied after i.m. injection in mouse gastrocnemius. Hemorrhage was observed ...
Skeletal muscle degeneration and regeneration after injection of bothropstoxin-II, a phospholipase A2 isolated from the venom of the snake Bothrops jararacussu
(1991)
A myotoxic phospholipase A2, named bothropstoxin II (BthTX-II), was isolated from the venom of the South American snake Bothrops jararacussu and the pathogenesis of myonecrosis induced by this toxin was studied in mice. ...
A randomized blinded clinical trial of two antivenoms, prepared by caprylic acid or ammonium sulphate fractionation of IgG, in Bothrops and Porthidium snake bites in Colombia: correlation between safety and biochemical characteristics of antivenoms
(1999-06)
A randomized blinded clinical trial was performed in 53 patients bitten by Bothrops sp. and Porthidium sp. in Antioquia and Chocó, Colombia, in order to compare the efficacy and safety of two antivenoms made of whole IgG ...
