Body distribution of Bothrops asper (terciopelo) snake venom myotoxin and its relationship to pathological changes
(1988)
The distribution of 125I-labelled Bothrops asper myotoxin following i.m. and i.v. injections was studied in mice. After i.m. administration the toxin was concentrated in the injected gastrocnemius muscle, with relatively ...
Cariotipos de diez especies de serpientes costarricenses de la familia Viperidae

Using a pure myotoxin (myotoxin a) isolated from prairie rattlesnake Crotalus viridis viridis) venom, a comparison between two methods for quantitating myonecrosis in mice was made. Measurement of creatine kinase (CK) ...
Mecanismo de acción de miotoxinas aisladas de venenos de serpientes
(1984)
Biochemically and pharmacologically, myotoxins isolated from snake venoms can be placed in four main groups: myolaxic phospholipases A, low molecular weight basic toxins, cardiotoxins, and hemorrhagic myotoxins. The myotoxic ...
