Introduction Accidental scorpion sting is a serious health issue of poor communities in tropical and subtropical areas throughout the world. Out of 1500 scorpion species distributed throughout the world, only 50 scorpion species have been proved lethal to human [1]. The symptoms of scorpion envenomation depend on species, age, venom composition and the victim’s physiological response. Scorpion ...

OBJECTIVE To study the efficacy of anti-scorpion venom plus prazocin. METHODS Comparison of clinical features, outcome and duration of stay between children receiving anti-scorpion venom plus prazocin or prazocin alone for management of red scorpion envenomation. RESULTS Requirement for dopamine and requirement and duration of dobutamine therapy were significantly less in patients received ...

The effect of Odonthobuthos doriae (O.d) scorpion venom at 0/3, 1 and 3, 10 µg/ml concentrations were investigated on nerve-muscle transmission, using the Twitch tension technique. A concentration of 0.3 µg/ml caused a small change in the twitch height in response to indirect muscle stimulation, but higher concentrations (1, 3, 10 µg/ml) caused a transient augmentation in twitch response follow...

Although many studies concerning the sensitivity mechanism of scorpion toxin-potassium channel interactions have been reported, few have explored the biochemical insensitivity mechanisms of potassium channel receptors toward natural scorpion toxin peptides, such as the KCNQ1 channel. Here, by sequence alignment analyses of the human KCNQ1 channel and scorpion potassium channel MmKv2, which is c...

Photoreactive derivatives of alpha- and beta-scorpion toxins have been used to analyze the subunit composition of Na+ channels in rat brain. In synaptosomes, both types of toxins preferentially labeled (greater than 85%) a component of 34,000 Da and, at a lower level, another component of 300,000 Da. Reduction of disulfide bridges shifted this latter band from 300,000 Da to 272,000 Da but did n...

an updated checklist of the scorpion fauna of iran, as well as a brief history of taxonomic research on scorpions of iran is presented. the checklist is based on records of scorpion species whose presence has been confirmed in iran through field expeditions, examination of scorpion collections, literature review, and personal communications from researchers. the scorpion fauna consists of 51 sp...
