In another context, the scorpion portrays human sexuality. [10] Scorpions are used in folk medicine in South Asia, especially in antidotes for scorpion stings. [10] One of the earliest occurrences of the scorpion in culture is its inclusion, as Scorpio, in the 12 signs of the Zodiac by Babylonian astronomers during the Chaldean period. [12]
The venom from Leiurus abdullahbayrami can be very toxic. The venom of this species is one of the most potent venoms of the Turkish scorpions, and it provokes severe symptoms in the victims. Proteins make up half of the dry weight of the crude venom. The venom in this species stimulates voltage-gated sodium and potassium channels. [11]
The crude venom of T. serrulatus contains different toxins. Some of the strongest derivates are the neurotoxins tityustoxin and toxin Ts-g. [3] Two types of toxins are considered to be responsible for the main toxic effect: toxin gamma (a β-type toxin) and tityustoxin (TsTX, an α-type toxin), both with a specific affinity to the sodium channel.

NTX accounts for only about 1% of the scorpion venom. [7] NTX is one of the best-studied toxic peptides from scorpion venoms. [6] It was the second purified toxin obtained from the genus Centruroides after neurotoxin II [8] and the first short peptide from scorpion venom to be reported in the literature. [9]
Scorpion venom is a mixture of neurotoxins; most of these are peptides, chains of amino acids. [114] Many of them interfere with membrane channels that transport sodium, potassium, calcium, or chloride ions. These channels are essential for nerve conduction, muscle contraction and many other biological processes. Some of these molecules may be ...
Scorpion toxins are proteins found in the venom of scorpions.Their toxic effect may be mammal- or insect-specific and acts by binding with varying degrees of specificity to members of the Voltage-gated ion channel superfamily; specifically, voltage-gated sodium channels, voltage-gated potassium channels, [3] and Transient Receptor Potential (TRP) channels.
A scorpion sting is an injury caused by the stinger of a scorpion resulting in the medical condition known as scorpionism, which may vary in severity. The anatomical part of the scorpion that delivers the sting is called a "telson". In typical cases, scorpion stings usually result in pain, paresthesia, and variable swelling.
Parabuthus transvaalicus is a dangerous, medically significant scorpion, which can both sting and spray its kurtoxin venom. [2] The first droplet of venom differs from the rest, and is referred to as "pre-venom". [4] A further potassium channel inhibitor, parabutoxin, has been isolated from the venom of P. transvaalicus.
