Tissue pathology induced by snake venoms: How to understand a complex pattern of alterations from a systems biology perspective?
(2010-01)
The study of snake venom-induced local tissue pathology has been predominantly based on experimental designs and concepts that view tissue alterations from a dichotomous, homogeneous and reductionist perspective. Experimental ...
Evaluation of antivenoms in the neutralization of hyperalgesia and edema induced by Bothrops jararaca and Bothrops asper snake venoms
(2002-10)
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 ...
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. ...
Toxicovenomics and antivenom profiling of the Eastern green mamba snake (Dendroaspis angusticeps).
(2016-03-16)
A toxicovenomic study was performed on the venom of the green mamba, Dendroaspis angusticeps. Forty-two different proteins were identified in the venom of D. angusticeps, in addition to the nucleoside adenosine. The most ...
Intravascular hemolysis induced by the venom of the Eastern coral snake, Micrurus fulvius, in a mouse model: Identification of directly hemolytic phospholipases A2
(Toxicon 90, 2014)
Intravascular hemolysis has been described in envenomings by the Eastern coral snake,
Micrurus fulvius, in dogs. An experimental model of intravascular hemolysis was developed
in mice after intravenous (i.v.) injection ...
Cariotipos de diez especies de serpientes costarricenses de la familia Viperidae
(1979)
All the karyotypes of ten snake species of the family Viperidae from Costa Rica have a diploid number of 36 chromosomes, 16 macro- and 20 microchromosomes; females show an heteromorphism in the fourth pair. The karyological ...
Inflammatory infiltrate in skeletal muscle injected with Bothrops asper venom
(1986)
The time-course and composition of inflammatory infiltrate in mouse gastrocnemius injected with Bothrops asper venom was studied. The venom induced myonecrosis, and a prominent decrease in muscle levels of creatine kinase ...
Cariotipos de las principales serpientes coral (Elapidae: Micrurus) de Costa Rica
(1979)
Se describen los cariotipos de las tres especies de serpientes de coral (Elapidae: Micrurus) más abundantes en Costa Rica: M. nigrocinctus, M. alleni y M. mipartitus. M. nigrocinctus presenta dos poblaciones cariotípicas ...
Understanding structural and functional aspects of PII snake venom metalloproteinases: Characterization of BlatH1, a hemorrhagic dimeric enzyme from the venom of Bothriechis lateralis
(2014-06)
A new homodimeric PII metalloproteinase, named BlatH1, was purified from the venom of the Central American arboreal viperid snake Bothriechis lateralis by a combination of anion-exchange chromatography, hydrophobic interaction ...
Pathogenesis of myonecrosis induced by crude venom and a myotoxin of Bothrops asper.
(1984)
The pathogenesis of skeletal muscle necrosis induced by crude Bothrops asper venom and isolated myotoxic phospholipase was studied using light and electron microscopy. White mice were injected intramuscularly with a dose ...
