After acupuncture needles were inserted on apkok(LI4) and Kokchi(LI11) accupoints, physiological changes induced by the varitions of 'Qi' were measured. The body temperature and pulse frequency were fromed to be decreased observed and we presumed that the needle insertion induced some changes of Qi in meridian and this seemed to be achieved by a certain process of Qi induction. We applied EAV, nervinemeter and pulse-taking machine which is widely used as oriental medicine instruments, to the same vounteers and observed the significant variations for each apparatus in spite of partial lack of reproducibility. In this paper, we described about the physical quantity measured by the medical appartatus and how it was related to the variation of Qi The proper conditions used for good oriental medicine instruments have also been suggested.
