In vivo effect of [50Hz] magnetic Filed on concentration of trace elements concerned with hemoglobin formation

ABSTRACT

The present in vivo experiment was designed to establish whether the exposure to 50 Hz magnetic field induces changes in blood and organs store of trace elements concentrations possibly associated with changes in hemoglobin level and induction of anemia. Rats were exposed to a high magnetic field strength of 0.5 T for one hour daily, the experiment was conducted for 30 days. Thirty-six rats were divided into control and magnetic field exposed rats. Iron, copper and zinc concentrations in blood, liver, kidney and spleen were estimated to assess the magnetic field effect on trace element storage in these tissues. MF exposure resulted in a depletion of the organs store of trace elements. A highly significant increase in blood copper and a decrease in zinc and iron levels were detected. A significant decrease was found in the hematological parameters, ceruloplasmin and ferritin [iron metabolism parameters]. The changes observed were associated with anemia during the first 14 days of MF exposure. The magnitude of anemia increased with increasing the exposure time
