Scorpion venoms, kidney and potassium
Toxicon, 2013Scorpion venoms cause renal injury by the interaction of renal ischemia due to intense renal vasoconstriction and inflammatory reactions due to proinflammatory cytokines and mediators. Renal vasoconstriction is not only induced by catecholamine storm but also by angiotensin II and the direct action of venom on vascular ion channels.

An Immunological Evaluation of Scorpion Venoms
The American Journal of Tropical Medicine and Hygiene, 1962Summary Studies have been presented on the interrelationships existing between scorpion venoms and antisera prepared against these venoms. Experiments designed to demonstrate reactivity of a number of venom samples representing Families Buthidae and Vejovidae have shown that a large number of antigenic fractions are shared among members of both of ...

Venom of the Scorpion Vejovis spinigerus
Science, 1968The chemical composition of lyophilized venom from Vejovis spinigerus is reported. At least 13 distinct bands were obtained on disc electrophoresis; on Sephadex G-50, four major peaks were found. The lethal activity was associated with the second peak.

Distribution of scorpion venom in locusts
Journal of Insect Physiology, 1965Abstract Redissolved freeze dried venom of Leiurus quinquestriatus H. & E. was labelled with I131, and injected into adults of Locusta migratoria migratorioides R. & F. which were dissected at intervals of 5 min to 216 hr following injection.

Physiological Action of Scorpion Venom
The American Journal of Tropical Medicine and Hygiene, 1960Summary Venom of the scorpion, Centruroides sculpturatus Ewing, caused hypertension, respiratory failure, and skeletal muscle stimulation in anesthetized animals. No significant action of the venom was found on isolated skeletal muscle preparations.

Snapshots of scorpion venomics
Journal of Arid Environments, 2015Scorpions are particularly well adapted to survival in extreme habitats (especially arid and semi-arid environments) and their ability to produce and deliver venoms is an important factor in this success. Scorpion venoms are very complex mixtures of different proteins and peptides.

Toxicon, 1971
The injection of small amounts of scorpion venom in blowfly larvae causes an immediate contraction and paralysis, the duration of which is dosage dependent. This response of fly larvae, considered to represent a peripheral neurotoxic effect of scorpion venoms, is suggested as a rapid and sensitive test for the quantitative estimation of the potency of ...

Modern Venom Profiling: Mining into Scorpion Venom Biodiversity
2014Scorpions and their sting are infamous for causing pain, morbidity, and, in some cases, death. However, research into scorpion venoms has revealed the presence of components that potentially have beneficial properties for humans. Such components may be developed into therapeutics or bioinsecticides.

The Canadian Entomologist, 1901
The prevailing belief in regard to scorpion stings seems to be correct: dangerons, but seldom fatal.However, there are scorpions and scorpions. Moreover, much depends upon the season and the part stung. Generally speaking, a sting in the dry season is much worse than one in the rainy season, because the venom becomes concentrated during the period of ...
