Circulating vasotocin in the snake Bothrops jararaca

Comparative Biochemistry and Physiology Part A: Physiology, 1992
1. There is biochemical and pharmacological evidence to suggest the presence of vasotocin in the blood and plasma of the snake Bothrops jararaca (Bj). 2. XE-64 extracts from Bj blood showed antidiuretic and hypotensive activities in rats and a contractile effect on rat isolated uterus, which was totally dialysable and inhibited by thioglycollate.

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

Distinct bothrojaracin isoforms produced by individual jararaca (Bothrops jararaca) snakes

Toxicon, 1997
Bothrojaracin (apparent mol. wt 27,000) is a potent inhibitor of thrombin previously isolated from the venom of Bothrops jararaca. Several molecular variants (isoforms) have been identified in a pool of venom collected from a large number of animals. In order to determine whether an individual snake produces a single type of bothrojaracin or multiple ...

The vasopressor action of angiotensin in the snake Bothrops jararaca

Comparative Biochemistry and Physiology Part A: Physiology, 1992
1. 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.

Bothrops jararaca Wied

1971
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.
