Jankowska,Milena; Pawlowska-Mainville,Agnieszka; Stankiewicz,Maria; Rogalska,Justyna; Wyszkowska,Joanna. AbstractBackground Extremely low-frequency (50 Hz) electromagnetic field (ELF-EMF) is produced by electric power transmission lines and electronic devices of everyday use. Some phenomena are proposed as “first effects” of ELF-EMF: the discrete changes in the membrane potential and the increase of the calcium channel activity as well as the intracellular concentration of Ca 2+ . Interaction of the scorpion alpha toxin with the sodium channel depends on the orientation of the charges and may be perturbed by changes in the membrane polarization. The toxin induces overexcitability in the nervous system and an increase in the neurotransmitters released with different consequences, mainly the paralysis of muscles. We assumed that the exposure to ELF-EMF 0.7 mT... Tipo: Info:eu-repo/semantics/article Palavras-chave: 50 Hz electromagnetic field; Alpha scorpion toxin; Cockroach; Bioelectrical activity.
