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.

Claims

1. A method of alleviating hyperglycemia in a living animal afflicted with same, the method comprising:

placing at least a portion of the animal in the field of an electromagnet; and

subjecting at least the portion of the animal to a pulsating magnetic field generated by said electromagnet by providing said electromagnet with an intermittent electric power supply having the following characteristics;

a pulse train of pulses having a pulse repetition rate of about 15 hertz plus or minus 0.5 hertz, a pulse width of about 350 microseconds and a pulse amplitude of about 60 millivolts to cause a decrease in the serum glucose level of the animal.

2. The method as claimed in claim 1 wherein said magnetic field is a substantially uniform, low level magnetic field of not more than 300 gauss and said electromagnet is spaced from the animal so as to provide an air gap therebetween.

3. The method as claimed in claim 2 wherein said pulse train is monopolar and uniformly periodic and is comprised of pure, unmodulated pulses.

4. The method as claimed in claim 2 wherein said magnetic field strength is from 5 to 30 gauss.

6. The method as claimed in claim 1 wherein said pulse train is uniformly periodic.

7. The method as claimed in claim 1 wherein said pulse is monopolar and uniformly periodic and wherein said magnetic field is substantially uniform.

8. The method as claimed in claim 1 wherein said animal is constantly subjected to said magnetic field for a period of time of four to sixteen hours in duration.

5. The method as claimed in claim 11 wherein said magnetic field is about 15 gauss and is uniform.
