Abstract: Over the past few years, our environment has become seething electromagnetic smog that bombards our
bodies every second of every day. Because electro-magnetic fields are invisible, we do not even realize they are
there, although they are battering us mercilessly. Special attention has been given to the biological effects of
magnetic fields. Thirty six male albino rats (Rattus norvegicus) were utilized in the present work to study the effects
of static magnetic field (SMF) equaling 2 ml tesla on the spleen and some haematological parameters. Magnetic
exposure was applied for ٦0 minutes for 3 days per week for two weeks. One day following magnetic exposure, the
spleen showed congestion in the splenic sinusoids accompanied with thickening of the splenic capsule. A significant
increase in the white blood cells and blood platelets was accompanied by enlargement of the white pulp were
detected. Seven days following magnetic exposure, an increase of haemoglobin concentration; haematocrit and red
blood cells was recorded accompanied with a highly significant decrease in blood iron. Later on, such increase was
followed by a significant decrease in most haematological parameters after fifteen days of magnetic exposure.
Hemosiderin granules were observed in the dilated splenic sinusoids at the areas of congestion. The splenic tissues
and the haematological parameters appeared almost normal and manifested a tendency towards recovery after thirty
days following magnetic exposur |
