Abstract
Exposure to
electromagnetic fields (EMF) is ubiquitous for almost all individuals living in
industrialized countries. Epidemiological and laboratory studies suggest that
exposure to Extremely Low Frequency (ELF) EMF increase cancer risk. The immune
system functions as one of the body's main protective mechanisms, and Natural
Killer (NK) cells are a subset of lymphocytes that can destroy several types of
tumor cells. In this study, we investigated, NK cell activity after exposure to
a 50 Hertz (Hz), 2 mT magnetic field generated by a Helmholtz Coil. Nineteen
male, 10-12 week old guinea pigs were used, and NK cytotoxic activity of
splenocytes was measured in vitro by natural anticandidial colorimetric index.
The Mann-Whitney U test was applied for statistical analysis. NK cell cytotoxic
activity was decreased in exposed compared to controls. Our data suggests that
part of the immune system, the NK cell, can be suppressed by a 50 Hz magnetic
field.
