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.

The effect of experimental Bothrops jararaca envenomation on pregnant mice

Toxicon, 2006
The injury caused by the intramuscular injection of a single dose of Bothrops jararaca venom (0.24 mg/kg body weight) to mice on day 8 of pregnancy and examined on day 9 was investigated. Macroscopic and histological examination showed that the bothropic venom caused an increase in the incidence of fetal resorptions.

Active and inactive renin in the plasma of the snake bothrops jararaca

Comparative Biochemistry and Physiology Part A: Physiology, 1992
1. Complementing the work of Gervitz R. K., Hiraichi E., Fichman M. and Lavras A. A. C. Comp. Biochem. Physiol. 86A, 503-507 (1987), conditions have been established for measuring plasma renin activity (PRA) of the venomous snake Bothrops jararaca (Bj). 2. It corresponded to 115.9 +/- 11.5 ng equivalents of angiotensin II (AII) per ml of plasma (N = 13)

Biophysical properties and amino acid composition of Bothrops protease A, a proteolytic enzyme isolated from the venom of the snake Bothrops jararaca (jararaca)

Toxicon, 1983
Bothrops protease A, an arginine-ester hydrolase, is active on protamine, gelatin and insulin and was isolated from the venom of Bothrops jararaca in a homogeneous state, as judged by polyacrylamide gel electrophoresis and ultracentrifugal analyses. The enzyme has a molecular weight of 65,000 and a pI of 3.55.
