[The effect of scorpion venom (Androctonus australis) on a frog neuromuscular preparation].
We have shown that d-tubocurarine inhibits the effects of scorpion venom in striated muscles of the frog; we concluded that this venom acts mainly by releasing acetylcholine from the nerve terminal. Furthermore, scorpion venom is able to displace intracellular calcium.
