Use ofthe principle of nuclear magnetic resonance in biology

Book Abstract by: Sydney    

Original Author: Dr Raymond Damadian
Dr Raymond Damadian, a mathematician and bio-physicist from the New York State University Medical Center, studied the magnetic
resonance of water molecule protons in living cells (proton relaxation time, linked to H+lOH- hydrostatic bonds). He showed that these protons, when they formed part of a cancer cell, had a different relaxation time to protons from healthy tissues. All healthy tissues have times ofbetween 0.26 and 0.90 seconds, whereas the same tissues when diseased by tumour contain less bound water, which requires 1 and 1.5 seconds to delete the orientation effects of the resistant field . By a mechanical comparison, it may be considered that application ofNMR involves measuring the elasticity of the molecule. Dr R. Damadian came to the conclusion that the water molecules in cancerous tissue behaved differently to water molecules in normal tissue. ln his opinion, water was the major component of all cells and water molecules formed dipoles, i.e. groups formed by two electrical or magnetic charges, which were equal and of opposite polarity. ln a healthy cell, the dipoles align along the electrical fields created by ions (atoms or groups of atoms carrying an electrical charge) within the cells, in an order which corresponds to the cell structure. The electrical charges are perturbed and the structure of the cell is disorganised in the cancer cell, the centrioles which were perpendicular become parallel (explaining the loss in tempero-spatial positioning ofthe cell). The work by Dr Damadian completely confirmed the bio-electronic explanation for the origin of cancerous cells
