Scorpion venom cardiomyopathy

American Heart Journal, 1992
Cardiac function was evaluated by serial echocardiography in 30 children affected by scorpion stings. They could be separated into two groups on the basis of the initial echocardiogram. Group 1, consisting of 18 children, had normal left ventricular function, whereas group 2, consisting of 12 children, showed compromised left ventricular function ...

Mining on scorpion venom biodiversity

Toxicon, 2010
Scorpion venoms are complex mixtures of dozens or even hundreds of distinct proteins, many of which are inter-genome active elements. Fifty years after the first scorpion toxin sequences were determined, chromatography-assisted purification followed by automated protein sequencing or gene cloning, on a case-by-case basis, accumulated nearly 250 amino ...

Glycaemic responses to scorpion venom

Toxicon, 1972
Hyperglycaemia and liver and muscle glycogenolysis were produced in the rat by scorpion venom. These epinephrine-like effects may be mediated by the serotonin present in the venom. Liver slices, excised from venom treated rats, and incubated in Krebs-Ringer solution with bicarbonate and glucose, exhibited an increase of free fatty acid release ...

On the Toxicity of Scorpion Venom

The American Journal of Tropical Medicine and Hygiene, 1954
Summary The toxicity of the venoms of the Brazilian scorpions Tityus bahiensis and T. serrulatus is extremely variable at different times. The properties of venom extracted from triturated glands are different from those of the pure toxin obtained by milking the live scorpions. Mean lethal doses of from about 0.5 to more than 2.0 mg./kg.

Chromatographic Comparison of Scorpion Venoms

Science, 1960
The venom of seven species of scorpions was subjected to two-dimensional chromatographic analysis. Six major components were defined and tentatively correlated with the physiological activity of the venoms.

An Immunological Evaluation of Scorpion Venoms

The American Journal of Tropical Medicine and Hygiene, 1962
Summary 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 ...

5-Hydroxytryptamine in Scorpion Venom

Nature, 1956
IN the course of an investigation of the toxic factors in the venom of Leiurus quinquestriatus (H. and E., 1829), one of the constituents of the venom has been found to be 5-hydroxytryptamine.

Venom of the Scorpion Vejovis spinigerus

Science, 1968
The 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.
