The PL around"Waiqiu" acupuncture point consists of two sub-bands resulting from the favin dinucleotide(FAD) and phospholipids, and the porphyrins (including purine, isoxanthopterin and tryptophan), respectively. More emission due to FAD and phospholipids is found inside the acupuncture effect area of"Waiqiu"than its marginal or outside acupuncture regions. The ratio of emission intensity of FAD and phospholipids to one of porphyrins gradually decreases along the direction away fror the center of the acupuncture point. It implies that the component proportion changes between FAD, phospholipid and porphyrins around the "Waiqiu"acupuncture point. We suggest that there might be a certain relationship between redox function of FAD and""Waiqiu"acupuncture effect. C 2006 Elsevier B.v.
