1. Proteomic analysis of the venom of the social wasp Apoica pallens (Hymenoptera: Vespidae)
ABSTRACT Wasps are a diverse group of insects that possess a sting apparatus associated with a venom gland, which is used for predation and colony defense. The biochemistry of Hymenoptera venom has been evaluated in relation to allergy and immunology, and proteomics has been shown to be a powerful tool for the identification of compounds with pharmacological

2. Sequence analysis of the cDNA encoding for SpCTx: a lethal factor from scorpionfish venom ( Scorpaena plumieri )
Abstract Background: Lethal factors are multifunctional oligomeric proteins found in the venomous apparatus of Scorpaeniformes fish. These toxins elicit not only an array of biological responses in vitro but also cardiovascular disorders and strong hemolytic, nociceptive and edematogenic activities in vivo. This work describes the cloning and molecular iden

3. A Histological Study on Venom Apparatus of Montivipera xanthina (Gray, 1849) (Serpentes, Viperidae)
ABSTRACT This is the first report describing morphological and histological structure of venom apparatus in Montivipera xanthina. The venom gland apparatus of M. xanthina was composed of four distinct parts, main venom gland, primary duct, accessory gland and secondary duct. The main venom gland was composed of acini. The accessory gland was formed by long a

4. Thalassophryne nattereri fish venom: from the envenoming to the understanding of the immune system
Thalassophryne nattereri (niquim) is a venomous fish found off North and Northeast coast of Brazil, where it is known by the severity of the accidents involving humans. This review article is divided into four topics. The first one provides a brief description of the animal biology and its distribution off Brazilian coastal waters, the venom apparatus, signs

5. Effects of the European hornet ( Vespa crabro Linnaeus 1761) crude venom on its own species
Background Lethal dose 50% is a classical index of toxicity that usually employs small rodents as experimental animals. Therefore, scarce data are available on the effects of venom on invertebrates, particularly the impact of wasp venom on its own species. Findings In the present study, the lethality of Vespa crabro venom on its own species was studied. Let

6. Glândula acessória e ducto primário de serpente Bothrops jararaca durante o ciclo de produção de veneno: um estudo morfológico. / Acessory gland and primary duct of the Bothrops jararaca snake during the venom production cycle: a morphological study.
The accessory gland (AG) and the primary duct (PD) are components of the venom gland apparatus of Bothrops jararaca snake. There are few studies about AG and PD and there is still controversy on whether the secretions released by these regions can modify the total venom. Our results show that AG presents simple secretory epithelium with mucous secretory cell

7. Fine structural analysis of the stinger in venom apparatus of the scorpion Euscorpius mingrelicus (Scorpiones: Euscorpiidae)
In this study, the morphology, histology and fine structure of the stinger, a part of the venom apparatus of Euscorpius mingrelicus (Kessler, 1874) (Scorpiones: Euscorpiidae) were studied by light microscopy and transmission electron microscopy (TEM). The stinger, located at the end section of the telson, is sickle-shaped. The venom is ejected through a pair

8. The venom apparatus and other morphological characters of the ant Martialis heureka (Hymenoptera, Formicidae, Martialinae)
Descrevemos e ilustramos o aparelho de ferrão e outros caracteres morfológicos da operária da formiga recentemente descrita Martialis heureka, uma suposta predadora especializada subterrânea, que pode representar o único sobrevivente de uma linhagem altamente divergente que teria surgido no início de diversificação das formigas. M. heureka foi descri

9. Morphological characterization of the venom apparatus in the wolf spider Lycosa singoriensis (Laxmann, 1770)
The wolf spider Lycosa singoriensis (Laxmann, 1770) (Lycosidae: Araneae) is distributed throughout central and eastern Europe, including Russia, Kazakhistan and Turkey. This study describes the venom apparatus morphology of L. singoriensis through scanning electron microscopy (SEM). Its structure follows the general architecture observed in other spiders. Ge

10. Histology and histochemistry of the venom apparatus of the black scorpion Androctonus crassicauda (Olivier, 1807) (Scorpiones: Buthidae)
The venom apparatus of the black scorpion Androctonus crassicauda has been characterized histologically and histochemically in the present study. The results showed that this apparatus consists of paired venom glands, each of which initially presents its own canal and posteriorily both fuse into a single common one. Each gland is covered by a sheath of stria

11. Analise histologica do aparato venenifero e caracterização farmaco-bioquimica da peçonha de Vitalius dubius (Araneae, Theraphosidae) / Histological analysis of the venom apparatus and biochemical and pharmacological characterization of venom from Vitalius dubius (Araneae, Theraphosidae)
Vitalius dubius is a medium-sized, non-aggressive tarantula found in southeastern Brazil. In this work, we examined the histological organization of the venom apparatus of V. dubius and investigated some biochemical and pharmacological properties of this spider´s venom. The venom apparatus consisted of two chelicerae fitted with large fangs for prey immobil

12. The venom gland of the scorpion species Euscorpius mingrelicus (Scorpiones: Euscorpiidae): morphological and ultrastructural characterization
The histology and ultrastructure of venom glands in the scorpion Euscorpius mingrelicus (Kessler, 1874) are described and illustrated in the current study for the first time by employing light microscopy and transmission electron microscopy (TEM). The venom apparatus is composed of a pair of venom glands and a stinger, both situated in the last segment of th
