实验动物:选用体重200g的雄性大白鼠。磁场条件:采用相当地球磁场(约500毫奥斯特)500倍的250奥斯特磁场的铁氧体磁石进行暴露。因为磁场对机体的影响力小,所以暴露时间为4周。测定参数:每日的体重、尿量、安静时的代谢量,同时测尿中钾、钠、钙的排泄量。 Experimental animals: Male rats weighing 200 g were used. Magnetic field conditions: A ferrite magnet of 250 Oersted field equivalent to 500 times the earth’s magnetic field (about 500 milli-oersted) was used for exposure. Because the influence of magnetic field on the body is small, so the exposure time is 4 weeks. Determination of parameters: daily body weight, urine output, quiet when the metabolism, while measuring urinary potassium, sodium, calcium excretion.
