In other words, we believe that more FAD and phospholipids exist in the efficient acupoint regions. As we know, FAD is virtually a kind of coenzyme which has a vital function for oxygen removal during the processes of the oxidation–deoxidation reaction. Therefore, we could relate the ‘‘Waiqiu’’ acupoint to certain biological redox functions, and suggest that the FAD’s function, the oxidation–deoxidation reac￾tion, might be an important processes in acupunc￾ture, which result in the special curative effects of acupuncture at acupoints. 4. Conclusions The PL at various positions of an acupoint ‘‘Waiqiu’’ has been systematically studied. The emission spectrum resulting from the superficial fascia tissue, in which the acupoint ‘‘Waiqiu’’ is located, consists of two sub-bands peaked at 590 and 525 nm, respectively. It is found that the PL due to FAD and phospholipids decreases gradu￾ally along the direction away from the center of the acupoint. Considering the special effect of FAD, i.e., the oxygen removal ability in oxida￾tion–deoxidation reactions, it is not unreasonable to think there is relatively high concentration of FAD in the acupoint ‘‘Waiqiu’’ and the redox effect might be important during the acupuncture.
