Local tissue damage induced by Bothrops snake venoms - A review [PDF]
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.

The binding of Bothrops asper myotoxin to mouse skeletal muscle was studied at both the light and electron microscope levels using the peroxidase anti-peroxidase technique. The toxin binds to muscle cell sarcolemma, and there are no intracellular binding sites.

South American snake venom proteins antigenically-related to Bothrops asper myotoxins. [PDF]
the presence of proteins antigenically related to Bothrops asper myotoxins in various snake venoms, mainly from South America, was investigated by using poluclonal and monoclonal antibodies. 2.

A Lys49-PLA2 Myotoxin of Bothrops asper triggers a rapid death of macrophages that involves autocrine purinergic receptor signalling [PDF]
Lys49-PLA(2) myotoxins, an important component of various viperid snake venoms, are a class of PLA(2)-homolog proteins deprived of catalytic activity.

Individual expression patterns of myotoxin isoforms in the venom of the snake Bothrops asper
1. In order to investigate the distribution of myotoxin isoforms in the snake Bothrops asper, venoms from individual specimens were analyzed by a cathodic electrophoretic system for basic proteins under native conditions. 2. The electrophoretic system resolved at least five bands with slight differences in mobility, corresponding to the fastest ...

Phospholipases A2 From Viperidae Snake Venoms: How do They Induce Skeletal Muscle Damage? [PDF]
Phospholipases A2 (PLA2s) are abundant components in snake venoms, which play important toxic roles. This review focuses on group II PLA2s endowed with myotoxic effects, present in Viperidae venoms. These PLA2s are subdivided into catalytically-active (

Immunoenzymatic quantitation of antibodies to Bothrops asper myotoxins after polyvalent antivenom administration in mice. [PDF]
Two quantitative enzyme-immunoassays (EIA) for Bothrops asper myotoxin and anti-myotoxin antibodies, respectively, were utilized to study their in vivo distribution in mice (Swiss, 18 to 20 g). 2. After polyvalent antivenom (0.4 ml) administration by the
