Scorpions can be found in almost all terrestrial ecosystem of varying climates and altitudes. Isolation and characterization of eleven neurotoxins from venoms of the scorpion Androctonus australis hectorButhus occitanus tunetatus and Leiurus quinquestriatus quinquestriatus.

Based on experience from Australia, where bandages have been applied to compress lymphatic circulation as part of first aid treatment to victims of Elapidae snakes, this technique has been proposed to avoid the absorption and distribution of scorpion venom, since the peptides in these venoms, especially the most toxic fractions, reach the systemic circulation by means of the lymphatic emponzonaminto These arthropods are the most common scorpion ectoparasites Although historically in Venezuela, Rhopalurus laticauda was the first scorpion whose venom biological activity was investigated 70most of the attention has been directed at the Tityus genus.

Effects of formalinization on the immunopharmacological characteristics of the venom of the Tityus scorpions and crossreactivity between these venoms. New epidemiological and clinical data on scorpion envenomation in the central north region of Venezuela. Purification of animal neurotoxins.

In the Northcentral region of Venezuela, the high frequency of accidents in children less than 6 years suggests that Tityus discrepans has intra-domiciliary habits Additionally, from ten specimens, the average yield of venom is 1.

Several works in Venezuela indicate the importance of the prompt treatment with scorpion antivenom 66, The clinical cholinergic manifestations by muscarinic activation is present in most of the envenomed patients 66,68,90, Guia para identificar escorpiones de Venezuela. The lack of basic scorpiofauna knowledge, distribution, clinical manifestations, and especially of specific treatments justify multidisciplinary studies. Tdf-I fraction contains peptides of 48 KD with a reversible curarizing action, so far unknown in other species of this genus 15,17, Some of them are located in areas of dense human population in the north of the Venezuela Figure 2 35,39, A retrospective epidemiological study.

In the Amazonas State a specimen of Tityus filodendron was collected in a bromelia 15 meters above the ground Rhopalurus laticauda shows adaptations to various microhabitats that can be seen by the coloration of the specimens 52,53, In this Venezuelan emponzonamienot forest, there is a significantly high human population, which is subjected to strong intervention by man.

In Venezuela, efforts have been made to develop toxoids for the prevention of serious envenoming by the genus Tityus. Most of these events Its incidence rate for was 25 cases per 10, inhabitants, which is not significantly different from the other hyperendemic municipality, Acosta, with an incidence rate of Of these, 6 Bshi [semi-arid emponzonakiento xerophyte vegetation or spinous bushes, with more evaporation than precipitation].

The yearly mean mortality rate was 0. In this way, patients can be quickly and appropriately treated, with the administration of specific scorpion antivenom.


Epidemiological characteristics of scorpion sting in Leon, Guanajuato, Mexico. There, the effects of human activity and environmental changes have allowed the expansion and colonization of this opportunist species, by modifying its habits, invading human dwellings, and displacing less dangerous autochthonous species Although there are not detailed national records of morbidity, scorpionism is important in some Venezuelan regions, such as the Federal District, and the states of Lara, Merida, Miranda, Monagas, Sucre, Trujillo, and Zulia 3,23,25,26,35,57 61,66,68,69, Adults stung in the north of Monagas State showed electrocardiographic alterations characterized by early auricular and ventricular contractions, elevation of ST segment, presence of J point and prominent U wave, infradislevel of ST segment, and sinusal tachycardia.

It escorpinoico of high quality, and so far there have been no serious adverse reactions seen. Probeer het later opnieuw.

The excretion conduct is single with cylindrical ciliated epithelium 82, Toxicon 51 1, Lack of effect of Tityus discrepans scorpion venom on isolated rabbit lung. Escodpionico the metropolitan area of Caracas and surrounding towns between and The total population has been calculated for each region and its municipalities with distribution of the Tityus genus.

So far, four classes of toxins that interact with the ionic channels have been identified and described. Since scorpion envenoming is of a seasonal character 6,25,59, similar to other venomous animals, especially snakes 94it is possible to predict the higher incidence periods and take the pertinent measures.

Escorponico this time, specimen weight was from Nomenclador de centros poblados. According to data, there are four large endemic areas for scorpion envenoming by the Escorpiionico genus in Venezuela Figure 3.
