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 ...

Indian black scorpion (Heterometrus bengalensis Koch) venom induced antiproliferative and apoptogenic activity against human leukemic cell lines U937 and K562

Leukemia Research, 2007
Venoms are rich source of several bioactive compounds that possess therapeutic potentials. The different constituents of scorpion venom can modulate cell proliferation, cell growth and cell cycle.

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.

Scorpion venoms, kidney and potassium

Toxicon, 2013
Scorpion 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.

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.

Distribution of scorpion venom in locusts

Journal of Insect Physiology, 1965
Abstract 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.

Scorpion venom phospholipases A2: A minireview

Toxicon, 2020
Many 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.

Snapshots of scorpion venomics

Journal of Arid Environments, 2015
Scorpions 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.

Physiological Action of Scorpion Venom

The American Journal of Tropical Medicine and Hygiene, 1960
Summary 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.

The effect of scorpion venom on blowfly larvae—A new method for the evaluation of scorpion venoms potency

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 ...
