Comparative action of toxins isolated from the venom of the scorpion (Androctonus australis) and the tentacles of the sea anemone (Anemonia Sulcata) on an isolated frog neuromuscular preparation]

We have shown that, if Scorpion venom is acting a skeletal muscle indirectly by releasing Acetycholine and directly by inducing an increase in intracellular free calcium, the main action of toxin II isolated from Anemonia Sulcata tentacles is presynaptic.
