Effect of Tityus serrulatus venom on cytokine production and the activity of murine macrophages

Mediators of Inflammation, Volume 11, Issue 1, Page 23-31, 2002., 2002
The purpose of this study was to investigate the effects of Tityus serrulatus venom (TSV) on murine peritoneal macrophages evaluated in terms of activation. The effects of crude TSV were analysed by detection of cytokines, oxygen intermediate metabolites (H2O2) and nitric oxide (NO) in supernatants of peritoneal macrophages.

Record of predation of the Brazilian yellow scorpion Tityus serrulatus (Buthidae) by the toad Rhinella diptycha (Bufonidae) in an urban area in southeastern Brazil

Acta Biológica Colombiana
Tityus serrulatus is one of the main causes of scorpionism in southeastern Brazil. However, little is known about its natural enemies, especially in urban areas, where this species is a major public health concern.

Effect of scorpion toxin on the enterochromaffin-like cells in normal and Trypanosoma cruzi-infected rats: a morphological study

Revista do Instituto de Medicina Tropical de São Paulo, 1989
Intravenous injection of scorpion toxin (Tityus serrulatus) in normal and Trypanosoma cruzi infected rats did not cause ultrastructural morphologic changes on enterochromaffin-like (ECL) cells of the stomach, although it induced a significant increase of

Developmental effects of Tityus serrulatus scorpion venom on the rat offspring

Brain Research Bulletin, 2008
Scorpion envenomation is a public health problem. Extensive research has been conducted to describe the systemic effects of scorpion venoms and their toxins, however, few reports are available about their effects on pre- and post-natal periods. Whole venom of the Tityus serrulatus scorpion was administered to rats on the 10th and 16th days of pregnancy

Effective Tityus serrulatus anti-venom produced using the Ts1 component

, 2008
Scorpion stings are a public health problem in Brazil, with most incidents involving the species Tityus serrulatus. Some T serrulatus toxins may act as immunogens for the production of a specific anti-venom, but many of the component toxins remain poorly

Central effects of Tityus serrulatus and Tityus bahiensis scorpion venoms after intraperitoneal injection in rats

Neuroscience Letters, 2009
A great number of studies on scorpion venoms associate their effects to the autonomic nervous system, and few data are available about their action on the central nervous system (CNS). The aim of this work was to evaluate some central effects after intraperitoneal injection of Tityus serrulatus or T. bahiensis scorpion venoms.
