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

Genotoxicity evaluation induced by Tityus serrulatus scorpion venom in mice

Toxicon, 2017
Tityus serrulatus is the scorpion associated with the most severe cases of scorpion envenoming in Brazil. However, there are no studies reporting the genotoxic effects of this venom in natural or experimental envenomations. It is well known that DNA-damage responses are providing opportunities for improving disease detection and management.

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.

Description of the male of Tityus kuryi Lourenço, 1997 and notes about males of Tityus stigmurus (Thorell, 1877) and Tityus serrulatus Lutz & Mello, 1922 (Scorpiones, Buthidae)

ZooKeys, 2014
The male of Tityus kuryi Lourenço, 1997 is described for the first time. Despite being very similar to the female, the male presents more robust metasomal segments. Additionally, the distribution of the sexual populations of another two species of

Litter size, effects of maternal body size, and date of birth in South American scorpions (Arachnida: Scorpiones)

Zoologia (Curitiba), 2009
We present new data on litter size and date of birth (month) for 21 South American scorpions species. We provide data for one katoikogenic species, the liochelid Opisthacanthus cayaporum Vellard, 1932 (offspring = 3; birth month: Jan); and for several ...

Inter- and intrapopulational genetic variability of Tityus serrulatus (Scorpiones, Buthidae)

Acta Tropica, 2009
In Brazil, there are near 20 genera and almost 120 species of scorpions of which 95% reproduce sexually. Parthenogenetic reproduction, however, may also take place. To gain insight into useful molecular markers in parthenogenetic scorpion species, we studied DNA polymorphism using two molecular approaches: simple sequence repeat anchored polymerase ...
