Corresponding measurements of delayed luminescence and impedance spectroscopy on acupuncture points.

Measurements of impedance spectroscopy and delayed luminescence have been performed on the acupuncture points PC4 and PC8 and other two control points of ten volunteers. The results show that there is a highly significant difference between the imaginary parts of the impedance of the acupunctural points and that of the control points. The same difference has not be observed in the values of the total number of counts of delayed luminescence. However a relationship has been detected between the imaginary part of the impedance of PC8 point and the total number of delayed luminescence counts, similar to that one found before for collagen, and it has been seen that the temporal dynamics of the two phenomena measured on one control points are similar. In particular, these final results confirm the close connection between the delayed luminescence and the dielectric properties of biological tissues.
