The vasopressor action of angiotensin in the snake Bothrops jararaca
Comparative Biochemistry and Physiology Part A: Physiology, 19921. Carotid blood pressure from anesthetized B. jararaca snakes was recorded in order to study angiotensin action in this reptile. 2. Whereas [Asn1,Val5] AII and AIII were less potent than [Asp1,Ile5] AII and [Asp1,Val5] AII, [Sar1,Ile5] AII was slightly more potent. 3. Captopril abolished the responses to AI (0.01-3 micrograms/kg). 4.

Immunization with liposome-encapsulated Bothrops jararaca venom
Toxicon, 2000The venom of Bothrops jararaca (BjV) snake was encapsulated into liposomes. The toxicity and ability of the resultant liposomes to protect mice were evaluated. No acute toxicity was found in mice, when liposomes were subcutaneously injected whereas the same dose of venom emulsified in Freund's adjuvant caused the mice to die.

The humoral immune responses of patients bitten by the snake Bothrops jararaca (jararaca)
Toxicon, 1990The 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.

Hesperetin as an inhibitor of the snake venom serine protease from Bothrops jararaca.
Toxicon, 2021The majority (90%) of the snakebite envenomation in Brazil accounts for Bothrops from the Viperidae family. Some snake venom serine proteases provoke blood coagulation in ophidian accident victims because of their fibrinolytic activity and one of those ...

Blood-clotting Activity of the Venom of Bothrops jararaca
Nature, 1959THE 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.

Snakebite accidents are a public health problem that affects the whole world, causing thousands of deaths and amputations each year. In Brazil, snakebite envenomations are caused mostly by snakes from the Bothrops genus.

Angiotensin receptor in the heart of Bothrops jararaca snake
European Journal of Pharmacology, 2001Angiotensin 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.

The karyotypes presented were obtained from short term blood cultures. The sex chromosomes, male — ZZ, female — ZW correspond to the 4th pair of macrochromosomes. The karyotypes are from a male specimen of Santa Catarina and from a female specimen of Sao Paulo, Brazil. Both are preserved in the Collection of the Instituto Butantan.

Separation of the coagulant components of Bothrops jararaca venom
Toxicon, 1970The venom of Bothrops jararaca has been separated into two distinct coagulant components by chromatography on DEAE cellulose, and the presence of an inhibitor in the crude venom detected.
