Abstract :
A therapy apparatus with rotating high magnetic field was invented in order that a standard magnetic field can be used for experiment. Its main technical specifications are: field intensity of magnet, 6000 Gauss; top surface diameter of rotating magnet, Φ540 mm; effective working surface diameter of rotating magnetic field, Φ500 mm; power, single phase AC 220 V or three phase, AC 380 V 0.75 kilowatt; noise, ⩽55 dB; rotating speed of magnet body, 0-720 R/M; overall dimensions; 2100×840×760 mm; total weight, 650 Kg. New Zealand rabbits and voluntary patients were treated with the WD-HMF 6000 magnetic therapy apparatus and their plasma beta-endorphin was determined by RIA. The present investigation aimed at studying the influence of magnetic field on neuroendocrine. The results showed that magnetic field made plasma beta endorphin of rabbits and patients increase significantly. It may be a theoretical basis for magnetic analgesia
