Myocardial necrosis after envenomation by the scorpion Tityus serrulatus

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2002
A 4 years old boy died a few hours after he had been stung by a scorpion (Tityus serrulatus). At necropsy, there were multiple foci of coagulative myocytolysis in the myocardium and pulmonary oedema. Myocardial necrosis was probably associated with the sympathetic storm induced by scorpion envenomation, and may have contributed to cardiac failure and ...

Enzymes with gelatinolytic activity can be found in Tityus bahiensis and Tityus serrulatus venoms

Toxicon, 2002
Enzymes with gelatinolytic activity were detected in Tityus bahiensis and Tityus serrulatus venom. Their activity was optimal at pH 8.0 in SDS-PAGE-gelatin. They were inhibited by PMSF but not by iodoacetamide, pepstatin or phenantrolin in the assay conditions used. This suggests that these enzymes are serine proteases.

Reproductive toxic effects of Tityus serrulatus scorpion venom in rats

Reproductive Toxicology, 2008
Tityus serrulatus is the most venomous scorpion in Brazil. Little is known about the effect of maternal exposure to the venom on fetal development. We investigated the effect of low to moderate doses of the venom (0.3 or 1.0 mg/kg s.c. on either day 5 or day 10 of gestation) on pregnant rats and on their offspring.

Ipomoea asarifolia neutralizes inflammation induced by Tityus serrulatus scorpion venom

Journal of Ethnopharmacology, 2014
Envenoming caused by scorpion sting is a serious public health problem. In Brazil, 13,038 accidents caused by venomous animals have been reported. Of this total, 53% of the cases and 14 deaths were caused by scorpions. Furthermore, Tityus serrulatus (Buthidae) is the most dangerous scorpion due to the high toxicity of its venom.

Immune cells recruitment and activation by Tityus serrulatus scorpion venom

Toxicon, 2011
Despite several studies showed that the Tityus serrulatus scorpion venom (Tsv) induces an inflammatory response, just a few have investigated the effect of the venom on the immune response. Therefore, the aim of this study was to evaluate alterations of venom application on lymphoid organs and on the recruitment and activation of cells and also on the ...

Renal effects and vascular reactivity induced by Tityus serrulatus venom

Toxicon, 2005
Tityus serrulatus, popularly known as yellow scorpion, is one of the most studied scorpion species in South America and its venom has supplied some highly active molecules. The effects of T. serrulatus venom upon the renal physiology in human showed increased renal parameters, urea and creatinine.

Effects of Tityus serrulatus scorpion venom on thromboelastogram in rats

Toxicon, 2015
Thromboelastometry was used to evaluate blood coagulation in anesthetized rats after intravenous administration of Tityus serrulatus scorpion venom (Tx). Tracheostomy followed by catheterization of the left jugular vein and right carotid artery were performed for Tx or Ringer's lactate solution injection and blood sample harvesting, respectively. Blood

Acute pulmonary edema after Tityus serrulatus scorpion sting in children

The American Journal of Cardiology, 1993
Acute pulmonary edema due to scorpion toxins has been attributed to acute left ventricular failure resulting from massive catecholamine release or myocardial damage induced by the venom.1–3 It has been proposed that pulmonary edema could also result from increased pulmonary vascular permeability produced by vasoactive substances that may be released by

99mTc labeling of the scorpion (Tityus serrulatus) antivenom

Journal of Radioanalytical and Nuclear Chemistry, 2008
F(ab’)2 is the fragment involved in the immunotherapy for scorpion stings and it would be convenient to label it with 99mTc for organ distribution and pharmacokinetics studies. The aim of the present study was to label scorpion antivenom F(ab’)2 with 99mTc keeping its biological activity, integrity and stability.
