Common behaviors alterations after extremely low-frequency electromagnetic field exposure in rat animal model

Abstract

Naturally, the presence of electromagnetic waves in our living environment affects all components of organisms, particularly humans and animals, as the large part of their body consists of water. In the present study, we tried to investigate the relation between exposure to the extremely low-frequency electromagnetic field (ELF-EMF) and common behaviors such as body weight, food and water intake, anorexia (poor appetite), plasma glucose concentration, movement, rearing and sniffing in rats. For this purpose, rats were exposed to 40 Hz ELF-EMF once a day for 21 days, then at days 1, 3, 7, 14 and 21 after exposure, any changes in the above-mentioned items were assessed in the exposed rats and compared to the non-exposed group as control. Body weight of irradiated rats significantly increased only a week after exposure and decreased after that. No significant change was observed in food and water intake of irradiated rats compared to the control, and the anorexia parameter in the group exposed to ELF-EMF was significantly decreased at one and two weeks after irradiation. A week after exposure, the level of glucose was significantly increased but at other days these changes were not significant. Movements, rearing and sniffing of rats at day 1 after exposure were significantly decreased and other days these changes did not follow any particular pattern. However, the result of this study demonstrated that exposure to ELF-EMF can alter the normal condition of animals and may represent a harmful impact on behavior.

Tratamiento a largo plazo con campos electromagnéticos en un modelo animal de la enfermedad de Parkinson

“…La estimulación electromagnética de 60 Hz mostró tener efectos benéficos en el modelo animal de la EP al aplicarla durante largo plazo. En particular, el tratamiento empleado no afectó el peso de los animales control y con falsa lesión, similar a lo previamente reportado por otros autores (Lee et al, 2006;Mahdavi, Sahraei, Rezaei-Tavirani & Najafi, 2016). El porcentaje de aumento de peso en los animales lesionados expuestos al CEM sugiere al resultar similar al de los animales control, que el tratamiento electromagnético impide la pérdida de peso evidenciada en el modelo de EP.…”
