Abstract
Experiments to examine the existence of Qi(external Qi-gong)from a healer who has been known to emit strong magnetic field was undertaken. Firstly, we confirmed that he could emit 10mGauss(30-400Hz)magnetic field. Then, the influence to human Natural Killer(NK)cell activities by Qi emission was tested comparing to that without Qiemission. NK cell activity with Qi emission was significantly(P<0.01)increased than that without Qi emission. But no difference was seen when alternating magnetic field(20-100Gauss, 50Hz)was radiated by magnetic field emitting aparatus to NK cells. The results suggested the existence of Qi which had increasing effect on NK cell acturtus invitro not by the effect of magnetic field.
