Intraspecific variation in the venoms of the South American rattlesnake (Crotalus durissus terrificus)

Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 2000
The venom of eight individual Crotalus durissus terrificus snakes from the State of Minas Gerais, Brazil, in addition to pooled venom from Butantan Institute, were compared. Snakes were captured in distinct locations, some of them 600 km apart: Conselheiro Lafaiete, Entre Rios de Minas, Itauna, Itapecerica, Lavras, Patos de Minas, Paracatu, and Santo ...

Immunosuppresive role of principal toxin (crotoxin) of Crotalus durissus terrificus venom

Toxicon, 2004
The composition of the crotalic venom and the immunochemistry and/or pathophysiological characterization and main components were well studied. However, few studies have been carried out to investigate the effect of toxins of this venom on the development of the immune response.

Absence of myocardial involvement in children victims of Crotalus durissus terrificus envenoming

Toxicon, 2003
The myotoxic activity of the venom of Crotalus durissus terrificus is demonstrable by increased serum levels of the enzymes creatine kinase (CK), lactate dehydrogenase (LD), and aspartate aminotransferase. Serial measurements of CK, LD and their isoenzymes in bite victims showed a pattern similar to that observed in acute myocardial infarction ...

Seasonal variation of peptidase activities in the reproductive tract of Crotalus durissus terrificus

General and Comparative Endocrinology, 2009
Seasonal quantitative patterns of acid (APA), basic (APB), puromycin-sensitive (APN-PS) and puromycin-insensitive neutral (APN-PI), cystyl (CAP), dipeptidyl IV (DPPIV), type-1 pyroglutamyl (PAP-I) and prolyl-imino (PIP) aminopeptidases and prolyl oligopeptidase (POP) activities in soluble (SF) and solubilized membrane-bound (MF) fractions from ductus ...

Inhibitory potential of Crotalus durissus terrificus venom on measles virus growth

Toxicon, 2003
This paper presents the antiviral activity found in a snake with Crotalus durissus terrificus venom (Cdt), studied by use of microplate inhibition assay, using measles virus (MV). Cdt at concentrations below 100 microg/ml showed no cytotoxicity for Vero cells. This study shows the optimal conditions for cell treatment and infection.

Crotalus durissus terrificus snake venom regulates macrophage metabolism and function

Journal of Leukocyte Biology, 2001
Abstract In the present study, we examined the effect of Crotalus durissus terrificus venom on rat macrophage metabolism and function. Two hours after subcutaneous injection of the venom, peritoneal resident (unstimulated), elicited (thioglycollate-stimulated), and activatedMycobacterium bovis strain bacille Calmette Guérin (BCG ...

Gyroxin, a toxin from the venom of Crotalus durissus terrificus, is a thrombin-like enzyme

Toxicon, 1988
We report a simple method for the isolation of gyroxin, a protein from the venom of the South American rattlesnake Crotalus durissus terrificus. The intravenous injection of gyroxin into mice produces temporary episodes characterized by opisthotonos and rotations around the long axis of the animal.

Ribosomal proteins from the liver of the South American rattlesnake,Crotalus durissus terrificus

Experientia, 1974
In Ribosomen von Klapperschlangenleber ist das Verhaltnis RNS/Protein 0,96, und das Molekulargewicht der meisten ribosomalen Proteine liegt zwischen 10 und 45×103 Daltons. Das durchschnittliche Molekulargewicht ist 22000 bzw. 26000 Daltons fur die Proteine der 40 S bzw. der 60 S Untereinheit.

[Early effect of Crotalus durissus terrificus venom on kidney circulation].

Acta physiologica latino americana, 1981
Local blood flow was measured in renal cortex (1 mm below cortical surface) by means of the hydrogen clearance method in urethanized rats. Recording of blood pressure from femoral artery was performed. Crotalus durissus terrificus venom injection (one mg/kg i.v.) significantly decreased cortical blood flow at 10 min, without a significant arterial ...
