Effect of Low Frequency Electromagnetic Fields on [3H]Glucose Uptake in Rat Tissues

The aims of this study were to evaluate the influence of an extremely low-frequency electromagnetic field (Elf-EMf) on [3H]glucose uptake in the peripheral tissues and organs of rats. rats were exposed to elF-emF (frequency-10 Hz, induction -1.8-3.8 mT) one hour daily for 14 consecutive days. control animals were sham exposed. on the 15th day (24 hours after last exposure) rats were injected with D-[3H]-6glucose 500μci/kg iP. Fifteen minutes later animals were sacrificed by decapitation and peripheral tissues were excised and examined for radioactivity (desintegrations per minute, DPm/100 mg wet tissue weight), which expressed [3H]glucose uptake. in most of the examined tissues and organs, such as liver, kidney, heart muscle, cartilage, connective tissue, tendon and skin, [3H]glucose uptake in elF-emF-exposed animals was significantly higher as compared to that in the sham control. exposure to elF-emF did not influence [3h]glucose uptake in the thoracic aorta and the skeletal muscle. It is concluded that Elf-EMf impacts tissue glucose uptake by facilitating glucose transport via cell membranes, dependent and probably also independent of its role in increasing insulin action in insulin-dependent tissues.
