Crotalus durissus terrificus Laurenti

1971
The karyotypes shown came from short term blood cultures. The female is heterogametic; the fourth pair of macrochromosomes consists of the sex chromosomes ZZ in the male, and ZW in the female. The karyotypes are from a male specimen of Minas Gerais and from a female of Sao Paulo, Brazil, both preserved in the Collection of the Instituto Butantan.

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 ...

Antineurotoxic activity of Galactia glaucescens against Crotalus durissus terrificus venom

Fitoterapia, 2008
Ethanolic extract of leaves of Galactia glauscescens (GGE) at concentration of 100 and 500 microg/ml prevented the neuromuscular paralysis induced by Crotalus durissus terrificus venom on mouse phrenic nerve-diaphragm preparation.

Snake Venomic of Crotalus durissus terrificus—Correlation with Pharmacological Activities

Journal of Proteome Research, 2010
The snake venomic of Crotalus durissus terrificus was analyzed by 2-D and 1-D electrophoresis and subsequent MS/MS and enzymatic assays. The venomic of the South American rattlesnake comprises toxins from seven protein families: phospholipases A(2), serine proteinases, ecto-5'-nucleotidases, metalloproteinases, nerve growth factors, phosphodiesterases,

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.

Purification of gyroxin from a South American rattlesnake (Crotalus durissus terrificus) venom

Toxicon, 1980
Abstract Gyroxin, a non-lethal toxin from Crotalus durissus terrificus venom was isolated by a procedure involving two chromatographies on Sephadex G-75 at pH 4·0; ion exchange chromatography on CM-Sephadex C-50 at pH 3·5 and chromatography on Sephadex G-75 at pH 4·0.

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.
