Glycaemic responses to scorpion venom
Toxicon, 1972Hyperglycaemia 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 ...

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 ...

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.

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 ...

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 ...

Scorpion venom phospholipases A2: A minireview
Toxicon, 2020Many venomous species, including snakes, bees and scorpions, contain a variety of secreted phospholipases A2 (sPLA2) that contribute to prey digestion and venom toxicity. Based on their primary structures, the different venom sPLA2 have been classified into four groups I, II, III and IX.

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.

Neurotoxic Proteins in Scorpion Venom
Journal of Toxicology: Toxin Reviews, 1984Scorpion venoms are complex mixtures of mucous, low molecular weight components (salts and organic compounds) and many basic, neurotoxic proteins (MR < 8000).

Hemodynamic and myocardial consequences of scorpion venom
The American Journal of Cardiology, 1980Abstract The hemodynamic effects of scorpion venom (Leiurus quinquestriatus) and the mechanism of heart failure were investigated in two groups of anesthetized spontaneously breathing dogs. The effects of different adrenergic and cholinergic blocking agents on the venom-induced hemodynamic changes were also evaluated. In one group the venom was given

On the Toxicity of Scorpion Venom
The American Journal of Tropical Medicine and Hygiene, 1954Summary 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.
