Using human leukocytes, we tested the two electric instruments such as “basic water producing electric instrument” and “high voltage electric treating instrument” which have been applied for promoting health and treating the disorders, and human hand palmar energy (called “Kikoh” in Japan and China) all of which emit electro-magnetic wave (i.e. far infrared ray) with wave length of 4-14 μm, in order to confirm whether they actually show the effect on the human cell activity; the effect of these instruments and hand palmar energies on normal or diseased human leukocyte functions was examined. The effect of electric instruments on human leukocytes was examined using the leukocytes obtained after the electric current was pulsed to the human normal or diseased subjects, and that of “Kikohshi” was tested by covering their hand palmars over the test tubes containing leukocyte suspensions.
The result revealed that they significantly increased [Ca
2+] i in neutrophils, phagocytosis and reactive oxygen species (ROS), O
2- generation by neutrophils, and blastogenetic response of lymphocytes to mitogens. Although other three did not show significant effect, palmar hand of one“Kikohshi”, Mr. Nukui significantly increased chemotactic activity of neutrophils from both normal and diseased subjects. Present study suggests that these electric instruments and “Kikohshi” actually potentiate cell functions possibly by increasing cellular [Ca
2+] i.
