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 ...
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 ...
Hyperalgesia induced by Asp49 and Lys49 phospholipases A2 from Bothrops asper snake venom: pharmacological mediation and molecular determinants
(2003-05)
The ability of Lys49 and Asp49 phospholipases A2 (PLA2), from Bothrops asper snake venom, to cause hyperalgesia was investigated in rats, using the paw pressure test. Intraplantar injection of both toxins (5–20 μg/paw) ...
Dissociation of enzymatic and pharmacological properties of piratoxins-I and -III, two myotoxic phospholipases A2 from Bothrops pirajai snake venom
(2001-03-15)
Piratoxins (PrTX) I and III are phospholipases A2 (PLA2s) or PLA2 homologue myotoxins isolated from Bothrops pirajai snake venom, which also induce myonecrosis, bactericidal activity against Escherichia coli, disruption ...
Niveles de inmunoglobulinas séricas (IgG, IgA e IgM) en adultos jóvenes sanos, por el método de inmunodifusión radial
(1985)
Se determinó la concentración de IgG, IgA, e IgM en el suero de 49 estudiantes universitarios normales, de 18 a 25 años. Para esto se empleó el método de inmunodifusión radial, en placas comerciales. Los resultados fueron ...
Producción de placas de inmunodifusión radial para la cuantificación de IgG humana
(1985)
Se describe un método para la preparación de placas de inmunodifusión radial para la cuantificación de la lgG humana. El método se basó en las siguientes etapas: (1) aislamiento de lgG de suero normal
mediante cromatografía ...
Edema-forming activity of bushmaster (Lachesis muta stenophrys) and Central American rattlesnake (Crotalus durissus durissus) venoms and neutralization by a polyvalent antivenom
(1985)
The edema effect induced in mice by venoms of Crotalus durissus durissus and Lachesis muta stenophrys was studied . Minimum edema-forming doses were 11 and 5 ug, respectively . Edema developed very rapidly after injections ...
N-Formyl-Perosamine Surface Homopolysaccharides Hinder the Recognition of Brucella abortus by Mouse Neutrophils
(2016-06)
Brucella abortus is an intracellular pathogen of monocytes, macrophages, dendritic cells, and placental trophoblasts. This bacterium
causes a chronic disease in bovines and in humans. In these hosts, the bacterium also ...
Isolation from a polyvalent antivenom of antibodies to a myotoxin in Bothrops asper snake venom
(1985)
Antibodies against Bothrops asper rmyotoxin were purified from a polyvalent antivenom by affinity chromatography . These antibodies neutralized most of the myotoxic activity of crude B. asper venom, as judged by histologic ...
Venomics and antivenomics of Bothrops erythromelas from five geographic populations within the Caatinga ecoregion of northeastern Brazil
(2015-01-30)
The Caatinga lancehead, Bothrops erythromelas, is a medically relevant species, responsible for most of the snakebite accidents in most parts of its distribution range in northeastern Brazil. The spectrum and geographic ...
