Iodination of toxin II from the sea anemone Anemonia sulcata gives a labeled monoiododerivative that retains 80% of the original neurotoxicity. This derivative binds specifically to rat brain synaptosomes at 20 degrees C and pH 7.4 with a second-order rate constant of association ka = 4.6 x 10(4) M-1 sec-1 and a first-order rate constant of dissociation kd = 1.1 x 10(-2) sec-1. The binding occu...

OBJECTIVE Envenomation by Mesobuthus tamulus scorpion sting can result in serious cardiovascular effects. Scorpion antivenom is a specific treatment for scorpion sting. Evidence for the benefit of scorpion antivenom and its efficacy compared with that of commonly used vasodilators, such as prazosin, is scarce. We assessed the efficacy of prazosin combined with scorpion antivenom, compared with ...

BACKGROUND Scorpion antivenom (SAV) is specific antidote to scorpion venom..SAV did not prevent the cardiovascular morbidity and mortality (autonomic storm), hence its utility in the management for severe scorpion envenomingmay be limited. Since 1983 the advent of prazosin revolutionized the management of severe scorpion sting. Since 2002 SAV against Indian red scorpion (IRS) for the treatment ...

Scorpion envenomation is a public health problem in tropical and subtropical countries. The majority of scorpion sting cases present with local pain at the site of sting and follow a benign clinical course. Severe intoxication may include cardiac and respiratory dysfunc-tion, leading to multi-system organ failure and death (1, 2). The deaths in scorpion sting envenomation (SE) are attributed to...

Background: Scorpionism is a public health problem in some provinces in Iran. The present study aimed to assess the clinical manifestations of scorpion envenomation in Shiraz and determine a clinical severity grading for Iranian scorpion envenomation in order to suggest a treatment guideline for emergency physicians. Methods: In this analytic retrospective study, all medical charts of patients ...

Scorpions use their venom in defensive situations as well as for subduing prey. Since some species of scorpion use their venom more in defensive situations than others, this may have led to selection for differences in effectiveness in defensive situations. Here, we compared the LD50 of the venom of 10 species of scorpions on five different species of target organisms; two insects and three ver...

Venom of Leiurus abdullahbayrami (Scorpiones: Buthidae) is an extremely toxic one and it stimulates voltage-gated sodium and potassium channels. In case of a stung by this scorpion; excessive catecholamine release occur and it impairs left ventricle contractility and consequently a heart failure occurs (scorpion sting-related cardiomyopathy). In addition to this cardiac-induced acute pulmonary,...

Rhopalurus junceus scorpion venom has demonstrated high cytotoxic activity in epithelial cancer cells. In the present study, the effect of scorpion venom on cell viability and apoptosis was evaluated in the MDA-MB-231 human breast carcinoma cell line. Cell viability was analyzed using MTT assay. The cell death event was examined trough end-point RT-PCR to identify the expression of apoptosis-re...
