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 ...
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 ...
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) ...
Biological and biochemical activities of Vipera berus (European viper) venom
(1993-06)
Vipera berus is widely distributed throughout the northern part of Europe and Asia. Characterization of several toxic effects of its venom in the mouse, as well as of in vitro enzymatic activities was performed. Vipera ...
Antivenomics of Atropoides mexicanus and Atropoides picadoi snake venoms: Relationship to the neutralization of toxic and enzymatic activities
(2010-09-30)
Viperid snakes of the genus Atropoides are distributed in Mexico and Central America and, owing to their size and venom yield, are capable of provoking severe envenomings in humans. This study evaluated, using an ‘antivenomics’ ...
Venom of the Coral Snake Micrurus clarki: Proteomic Profile, Toxicity, Immunological Cross-Neutralization, and Characterization of a Three-Finger Toxin
(2016)
Micrurus clarki is an uncommon coral snake distributed from the Southeastern Pacific of Costa Rica to Western Colombia, for which no information on its venom could be found in the literature. Using a 'venomics' approach, ...
Characterization of a novel snake venom component: Kazal-type inhibitor-like protein from the arboreal pitviper Bothriechis schlegelii
(2016-06)
Snake venoms are composed mainly of a mixture of proteins and peptides. Notably, all snake venom toxins have been assigned to a small number of protein families. Proteomic studies on snake venoms have recently identified ...
Phospholipase A2 enhances the endothelial cell detachment effect of a snake venom metalloproteinase in the absence of catalysis
(2015-10-05)
Microvessel disruption leading to hemorrhage stands among the most dangerous consequences of envenomings by snakes of the family Viperidae. A PIII metalloproteinase (SVMP), balteragin, purified from the venom of the snake ...
