Brazilian scorpion venoms: pharmacological aspects

RESUMO

This review focuses on clinical, epidemiological and therapeutic aspects of envenomation caused by scorpions in Brazil. In addition, it presents studies with the crude venom and neurotoxins isolated from Tityus serrulatus scorpion venom. Such studies show the pharmacological effects of the venom and isolated toxins in experiments that use the scorpion venom and neurotoxins as neurobiological tools to study receptor sites in sodium channels and neurotransmitter release.
