Local effects induced by coral snake venoms: Evidence of myonecrosis after experimental inoculations of venoms from five species
(1983)
The local effects induced by intramuscular inoculations of venons from six species of coral snakes were studied in mice. Venoms of Micrurus nlgrocinctus nigrocinctus, M. n . moquitensis, M. alleni, M. frontalis, M. aarinkauda ...
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 ...
Purification and characterization of BaH4, a hemorrhagic metalloproteinase from the venom of the snake Bothrops asper
(2000-01)
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 ...
Quantitation of myonecrosis induced by myotoxin a from prairie rattlesnake (Crotalus viridis viridis) venom
(1982)
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) ...
Hemorrhage Caused by Snake Venom Metalloproteinases: A Journey of Discovery and Understanding
(2016-03-26)
The historical development of discoveries and conceptual frames for understanding the hemorrhagic activity induced by viperid snake venoms and by hemorrhagic metalloproteinases (SVMPs) present in these venoms is reviewed. ...
Criptosporidiosis: una zoonosis de reciente interés
(Adel. Microbiol. Enf. Infecc 3 p. 159-181, 1984)
Cryptosporidium, a coccidium described in 1907. causes subclinical infections and
diarrhea in many vertebrates including man. It departs from other Cryptosporidiiae in
its localization on the brush border of epithelial ...

Justificación y objetivo: El comportamiento epidemiológico de los tumores malignos del país ha presentado un cambio en los últimos años; el cáncer de mama ha aumentado su incidencia hasta colocarse como el segundo tumor ...
p-Bromophenacyl bromide modification of Bothrops asper myotoxin II, a lysine-49 phospholipase A2, affects its pharmacological activities
(1993-09)
Modification of Bothrops asper myotoxin II, a lysine-49 phospholipase A2 variant, was carried out with p-bromophenacyl bromide. Modified toxin did not show changes in its charge and immunological properties but two of its ...
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 ...
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 ...
