    【Abstract】 Objective To study the effect of exposure to electromagnetic irradiation(EMF) for high-voltage transmission lines(HVTL) on rats.Methods Rats were exposed to EMF imitated for HVTL. Electrocardiogram and electroencephalogram were measured. The organic structure of lung and spermary were observed and phosphorylations of STAT3 were detected in spleen cells. Meanwhile the biochemical indexes of blood were determined. Results The expression of phosphor-stat3 was significantly increased. The content of alanine aminotransferase and number of white cells were remarkably improved. And the intension of peak in FTIR of haematoglobin was changed. The organic structure of lung and spermary were abnormal. Conclusion The EMF of HVTL could bring the intensifying effect on cell signal transduction, blood system and productive system of rats, respectively. ......
