Abstract: Apparatus and a non-invasive technique are disclosed for the control of glucose levels in living animals afflicted with hyperglycemia. The apparatus is used to apply a uniform, monopolar pulsed magnetic field to cause electric currents and field generation in the animal. The pulsed magnetic fields are obtained by transmitting individual pulses of direct current to Helmholtz coils located on opposite sides of the animal. The optimum pulse train configuration for the test animals, which were a breed of white rats, is a pulse repetition rate of 15 hertz, a pulse amplitude of 60 millivolts, and a pulse width of 350 microseconds. The generated field in the preferred embodiment was about 15 gauss. Although the treated rats did not have a normal serum glucose level, the depicted serum glucose levels are significantly lower than those of the control animals.
