Experimental myonecrosis induced by the venoms of South American Micrurus (coral snakes)
(1992)
Venoms from 11 taxa of Micrurus (coral snakes) from Brazil and Colombia were tested for myotoxic activity in mice. All venoms, except that of M. surinamensis, induced myotoxicity as judged by the increase in plasma creatine ...
Porcentaje y cifra absoluta de linfocitos T en sangre periférica por el método de rosetas E: estudio de cuarenta adultos sanos
(1985)
Se realizó la determinación del porcentaje y cifra absoluta de linfocitos T en sangre periférica a un grupo de 40 adultos sanos costarricenses, seleccionados de un grupo inicial de 58 voluntarios. Se utilizó un método de ...
Neutralization of myotoxic phospholipases A2 from the venom of the snake Bothrops asper by monoclonal antibodies
(1992)
The neutralization of two myotoxic phospholipases A2 from the venom of Bothrops asper, myotoxins I and II, by two murine monoclonal antibodies is reported. The monoclonal antibodies, MAb-3 and Mab-4, recognize different ...
The effect of myotoxins isolated from Bothrops snake venoms on multilamellar liposomes: relationship to phospholipase A2, anticoagulant and myotoxic activities
(1991-12)
The effect of four myotoxins isolated from Bothrops snake venoms on the release of peroxidase trapped in large multilamellar liposomes was studied and correlated to their phospholipase A2, myotoxic and anticoagulant ...
The Phospholipase A2 Homologues of Snake Venoms: Biological Activities and Their Possible Adaptive Roles
(2009)
A particular subgroup of toxins with phospholipase A2 (PLA2) structure, but devoid of this enzymatic activity, is commonly found in the venoms of snakes of the family Viperidae, and known as the PLA2 homologues. Among ...
DNase activity in Costa Rican crotaline snake venoms: quantification of activity and identification of electrophoretic variants.
(1991)
DNase activity of Costa Rican crotaline snake venoms from the genera Bothrops, Crotalus and Lachesis was quantified by an enzymodiffusion method on agarose/DNA gels containing ethidium bromide. The reaction is detected as ...
Exposure of dogs to spotted fever group rickettsiae in urban sites associated with human rickettsioses in Costa Rica
(2016-07)
The zoonotic transmission cycles of Rickettsia rickettsii and other spotted fever group (SFG) rickettsiae
in Latin America have usually been associated with rural or sylvatic environments, although domestic
dogs can be ...
An electrophoretic study on phospholipase A2 isoenzymes in the venoms of Central American crotaline snakes
(1992)
The number and isoelectric points of phospholipase A2 isoenzymes were studied in the venoms of 12 Central American crotaline snakes of the genera Bothrops, Crotalus, Lachesis and Agkistrodon. The study was carried out by ...
Cytotoxicity induced in myotubes by a Lys49 phospholipase A2 homologue from the venom of the snake Bothrops asper: Evidence of rapid plasma membrane damage and a dual role for extracellular calcium
(2007-12)
Acute muscle tissue damage, myonecrosis, is a typical consequence of envenomations by snakes of the family Viperidae. Catalytically-inactive Lys49 phospholipase A2 homologues are abundant myotoxic components in viperid ...
Turbidity of hyperimmune equine antivenom: the role of phenol and serum lipoproteins
(1993)
Twenty batches of polyvalent antivenom produced at the Instituto Clodomiro Picado were analyzed for turbidity, both before and after freezing-thawing and lyophilization. Eight batches became turbid upon freezing-thawing, ...
