EXPERIMENTAL STUDIES ON EXTREMELY-LOW-FREQUENCY PULSED MAGNETIC-FIELDINHIBITING SARCOMA AND ENHANCING CELLULAR IMMUNE FUNCTIONS

The previous observation with an electron microscope showed that extre mely low frequency (ELF) pulsed magnetic field (PMF) (with the maximum intensity of 0.6-2.0 T, gradient of 10-100 T.M-1, pulse width of 20-2 00 ms and frequency of 0.16-1.34 Hz) inhibited the growth of S-180 sar coma in mice and enhanced the ability of immune cell's dissolving sarc oma cells. In this study, the DNA contents of nuclei were assayed by u sing Faulgen Staining method. With an electron microscope and cell ste reoscopy technology it was observed that magnetic field affected the s arcoma cell's metabolism, lowered its malignancy, and restrained its r apid and heteromorphic growth. The magnetic field enhanced the cellula r immune ability and the reaction of lymphocytes and plasma. Since ELF pulsed magnetic fields can inhibit the growth of sarcomas and enhance the cellular immune ability, it is possible to use it as a new method to treat cancer.
