The myth of scorpion suicide: are scorpions insensitive to their own venom?
The resistance of the scorpion Androctonus australis to its own venom, as well as to the venom of other species, was investigated. A comparison of the electrical and pharmacological properties of muscle and nerve fibres from Androctonus australis with those from the crayfish Procambarus clarkii enabled us to understand the lack of effect of scorpion venom (110-180 microg ml-1) and purified toxi...

متن کاملBradykinin-Potentiating Factors of Venom from Iranian Medically Important Scorpions

Among the biomolecules of some animal’s venom, small peptides that lack disulfide bands known as Non-Disulfide Bridge Peptides (NDBPs) potentiate the bradykinin by preventing the conversion of angiotensin 1 to angiotensin 2 using the mec...
متن کاملIntraspecific Diversity of Scorpions Venom and Its Implication in the Pathophysiological Effects
The present study was conducted to explore the following hypotheses: (i) do scorpions (the Egyptian scorpion Scorpio maurus palmatus) from different geographical locations exhibit intraspecific diversity in their venom? (ii) if so, is the variation associated with ecological or genetic factors, geographical distance, and/or multiple interrelated factors? and (iii) do the different toxins produc...
