The kininases of Bothrops jararaca plasma.

Acta physiologica latino americana, 1987
Evidence is presented to suggest that kininase activity of Bothrops jararaca plasma is due to the presence of at least three distinct enzymes: a carboxypeptidase B type enzyme, similar to that found in human plasma in that its activity is enhanced by Co2+ (1 X 10(-4) M); a carboxypeptidase B type enzyme whose activity is unaffected by Co2+, and an ...

Effects of catecholamines on the isolated aorta of the snake Bothrops jararaca

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1992
1. Effects of catecholamines in snakes have been examined using an aorta preparation isolated from Bothrops jararaca. Adrenaline, noradrenaline and isoprenaline produced dose-dependent contractions on this preparation. The relative potency was adrenaline greater than noradrenaline greater than isoprenaline. 2.

Behaviour of the ZW sex bivalent in the snake Bothrops jararaca

Chromosoma, 1981
The behavior of the ZW sex bivalent was investigated in female meiosis of the poisonous snake Bothrops jararaca. The Z is euchromatic and synapses end to end with the W. The W chromosome shows a heterochromatic segment distally in the short arm. Pairing occurs between the long arm of the W and the slightly longer arm of the mediocentric Z.

Bradykinin-Potentiating Peptides from the Venom of Bothrops Jararaca

Pharmacological Research Communications, 1969
Bradykinin-potentiating factor (BPF) is a mixture of snake venom peptides which potentiate some of the pharmacological actions of bradykinin in vitro and in vivo (Ferreira, 1965; 1966). In this communication we describe the isolation of nine biologically active peptides from Bothrops jararaca venom, present the amino acid sequence determination of the ...

Bradykinin is involved in hyperalgesia induced by Bothrops jararaca venom

Toxicon, 2002
Bradykinin is involved in hyperalgesia (pain hypersensitivity) induced by Bothrops jararaca venom-intraplantar injection of B. jararaca venom (5microg/paw) in rats caused hyperalgesia, which peaked 1h after venom injection. This phenomenon was not modified by promethazine (H(1) receptor antagonist), methysergide (5-HT receptor antagonist), guanethidine

Distribution of somatostatin immunoreactivity in the brain of the snake Bothrops jararaca

General and Comparative Endocrinology, 2006
The distribution of perikarya and fibers containing somatostatin was studied in the brain of the snake Bothrops jararaca by means of immunohistochemistry using an antiserum against synthetic somatostatin. Immunoreactive perikarya and fibers were localized in telencephalic, diencephalic and mesencephalic areas.

Blood Coagulation Inhibitor in a Snake Plasma (Bothrops jararaca)

Thrombosis and Haemostasis, 1973
SummaryExperiments with plasmas samples from the snake B. jararaca and X. merremii have shown that the two differ markedly with respect to their reaction to bovine thrombin. The plasma of X. merremii appears to react in a manner very similar to that of normal human plasma both using the thrombin clotting test and using the antithrombin III assay of ...

Galanin-like immunoreactivity in the brain of the snake Bothrops jararaca

General and Comparative Endocrinology, 2006
The distribution of galanin-like immunoreactive perikarya and nerve fibers in the brain of the snake Bothrops jararaca was studied by means of immunohistochemistry using an antiserum against porcine galanin. Immunoreactive neurons were only detected in the infundibular recess nucleus.

Proteomic profiling reveals region-specific neuroimmune and apoptotic signatures induced by Bothrops jararaca venom toxins in the murine brain.

Biochimie
Human envenomation by Bothrops species can lead to systemic effects such as cardiovascular disturbances, coagulopathy, renal failure, and central nervous system (CNS) complications, including hemorrhagic and ischemic strokes.
