FY1995 report on the analyses of functional living systems using magnetic stimulation and magnetic fields; 1995 nendo jiki shigeki oyobi kyojiba ni yoru seitai kino kaimei

Abstract

The purpose of the project is to widen the understanding of the biological effects o magnetic fields and to search potential applications of biomagnetics to medical diagnosis and treatments. We developed a method of localized magnetic stimulation of the brain. By concentrating induced eddy currents on a target with a pair of opposing pulsed magnetic fields produced by a figure-eight coil, they were able to stimulate the human cortex within a 5 mm resolution. We studied the properties of diamagnetic water in static magnetic fields. The phenomenon that the surface of the water was pushed back by magnetic fields of higher gradients was observed. The behavior of oxygen dissolved in an aqueous solution under magnetic fields of up to 8T with a gradient of 50T/m was studied. For oxygen concentrations greater than 11 mg/l, a clear redistribution of dissolved oxygen was observed. Effects of strong magnetic fields on a process of dissolution of fibrin clots was studied. Fibrin polymers in water magneto-phoresically drifted in the direction of increasing magnetic fields, and dissolution of fibrin polymers by plasmin was accelerated. (NEDO)
