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 ...
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 ...
Isolation and characterization of basic myotoxic phospholipases A2 from Bothrops godmani (Godman's pit viper) snake venom
(1992)
Two basic myotoxic phospholipases A2 were purified to homogeneity from the venom of Bothrops godmani from Costa Rica by ion-exchange chromatography on CM-Sephadex. They have molecular weights of 14,300 (myotoxin I) and ...
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 ...
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 ...
Ultrastructural alterations in mouse capillary blood vessels after experimental injection of venom from the snake Bothrops asper (Terciopelo)
(1992-10)
Histological and ultrastructural alterations in capillary blood vessels were studied at various time intervals after im injection of 50 micrograms of Bothrops asper snake venom in mouse gastrocnemius muscle. Hemorrhage was ...
Cleavage of the NH2-Terminal Octapeptide of Bothrops asper Myotoxic Lysine-49 Phospholipase A2 Reduces Its Membrane-Destabilizing Effect
(1994-08)
Bothrops asper myotoxin II was cleaved with cyanogen bromide to determine the role of NH2-terminal amino acid residues in its ability to destabilize negatively charged liposomes and to induce myonecrosis. After treatment, ...
