Purification of a proteinase inhibitor from the plasma of Bothrops jararaca (jararaca)

Toxicon, 1991
A proteinase inhibitor was isolated from the plasma of Bothrops jararaca by three chromatographic steps: DEAE Sephacel, Phenyl Sepharose and Bio Gel P200. It inhibited caseinolytic and hemorrhagic activity of the whole venom of B. jararaca. Proteolytic activity of bothropasin and J protease, both metalloproteinases of the venom, were neutralized by the

Pharmacological evidence for a presynaptic action of venoms from Bothrops insularis (jararaca ilhoa) and Bothrops neuwiedi (jararaca pintada)

Toxicon, 2004
Whereas the presynaptic action of Crotalus durissus terrificus venom is well-established, Bothrops venoms have historically been considered to have only postsynaptic and muscular effects. However, some studies have also suggested a presynaptic action for these venoms. In this work, we used chick biventer cervicis preparations to compare the presynaptic

Sexual dimorphism in venom of Bothrops jararaca(Serpentes: Viperidae)

Toxicon, 2006
Bothrops jararaca is an abundant snake in Brazil, and its venom has been studied exhaustively. The species exhibits adult size dimorphism in which female are larger. We registered the growth in Snout-Vent Length and weight of one litter (with 11 females and 12 males). We compared growth curves and venom profile between male and female of B. jararaca in

The humoral immune responses of patients bitten by the snake Bothrops jararaca (jararaca)

Toxicon, 1990
The isotype and specificity of antibodies produced by patients bitten by B. jararaca and submitted to serum therapy were studied. The IgG anti-B. jararaca antibodies have large individual dispersion, starting to appear 10 days after the first bite and increasing to at least 80 days after the bite.

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 ...

Bradykinin-releasing Factor from Bothrops jararaca venom

Nature, 1960
IT was first shown by Rocha e Silva, Beraldo and Rosenfeld1 that the venom of the snake Bothrops jararaca contains a bradykinin-releasing substance. Holtz and Raudonat2 verified that the bradykinin releasing substance is precipitated with ammonium sulphate at the level of 60 per cent, is independent of the proteolytic activity on haemoglobin and ...

Blood-clotting Activity of the Venom of Bothrops jararaca

Nature, 1959
THE well-known blood-clotting activity of the venom from snakes of various species of the genus Bothrops has been attributed to its proteolytic activity1, although Michl2 (using paper electrophoresis) and Holz and Raudonat3 (using fractional precipitation with ammonium sulphate) have presented evidence against this point of view.

Thrombotic microangiopathy following Bothrops jararaca snakebite: case report

Clinical Toxicology, 2018
Thrombotic microangiopathy (TMA) is an uncommon and severe complication of snakebites, and is similar, in general, to hemolytic-uremic syndrome (HUS). We describe a case of TMA following envenomation by Bothrops jararaca.A 56-y-old-woman with controlled hypertension was transferred from a primary hospital to our ER ∼7 h after being bitten by B ...

Angiotensin receptor in the heart of Bothrops jararaca snake

European Journal of Pharmacology, 2001
Angiotensin II interacts with specific cell surface angiotensin AT1 and AT2 receptors and, in some vertebrates, with an atypical angiotensin AT receptor. This study was designed to characterize the angiotensin receptor in the heart of Bothrops jararaca snake.
