A patient with electrocardiographic abnormalities after scorpion sting, simulating early myocardial infarction, is reported here. Pulmonary edema and congestive heart failure accompanied these electrocardiographic changes. The etiology of the cardiovascular manifestations in severe scorpion sting is related to the venom effects on the sympathetic nervous system and the adrenal secretion of cate...
Long-chain scorpion toxins with four disulfide bridges exhibit various pharmacological features towards the different voltage-gated sodium channel subtypes. However, the toxin production still remains a huge challenge. Here, we reported the effects of different expression vectors on the pharmacological properties of a novel toxin BmαTX47 from the scorpion Buthus martensii Karsch. The recombinan...
In Cuba the endemic species of scorpion Rhopalurus junceus has been used in traditional medicine for cancer treatment. However, there is little scientific evidence about its potential in cancer therapy. The effect of a range of scorpion venom concentrations (0.1, 0.25, 0.5, 0.75 and 1mg/ml) against a panel of human tumor cell lines from epithelial (Hela, SiHa, Hep-2, NCI-H292, A549, MDA-MB-231,...
OBJECTIVE Scorpion antivenom was recently approved for use in patients with clinically significant scorpion envenomation in the United States; no formal economic analysis on its impact on cost of management has been performed. METHODS Three different strategies of management of scorpion envenomation with systemic neurotoxic symptoms in children were compared for cost minimization from a socie...
Scorpion stings are common in many tropical countries. Although most scorpion stings cause only localized pain without life-threatening envenoming, about one third of stings cause systemic envenoming which can result in death. Children are particularly sensitive to scorpion envenoming. The severity of scorpion stings is related to the presence of neurotoxins in the venom that cause a sudden rel...
In this study, Mesobuthus gibbosus and Mesobuthus eupeus eupeus venom samples were compared for lethality, in-vivo effects and proteins. Neutralization capacity of monovalent Androctonus crassicauda antivenom (RSHA anti-Ac) was tested against the lethal effects of the venoms. Venom was obtained from mature scorpions by electrical stimulation of the telson. The lethality of the venom and potency...
Scorpion envenomation is a real public health problem in many parts of the world, especially in North Africa, Central America, South America, the Middle East and India[1] [2] [3] [4], with over 1.2 million cases of scorpion stings and 3250 deaths each year worldwide[5]. Among the 1500 species described, venoms of at least 25 species are of medical importance for humans and the majority of those...
Scorpion stings are currently the leading cause of venom-related injury to humans in Brazil and are a significant public health problem globally. Only scorpions of the Tityus genus are of medical importance in Brazil, and Tityus serrulatus is responsible for the most serious envenomations and deaths. The toxic effects of scorpion envenomation are due to a massive release of sympathetic and para...
Scorpion toxins are important pharmacological tools for probing the physiological roles of ion channels which are involved in many physiological processes and as such have significant therapeutic potential. The discovery of new scorpion toxins with different specificities and affinities is needed to further characterize the physiology of ion channels. In this regard, a new short polypeptide cal...
