SXRF spectra from the Tiaokou acupoint(solid line)and the surrounding tissues out of Tiaokou(dotted line) Of the other three trace metals, Fe, Cu and Zn, the integrated intensity from Zn was the highest, followed by Fe and Cu. Figures 4-6 show spectra collected from and in the vicinity of Jianshi Tiaokou and Xiajuxu acupuncture points. The parameter @i was taken to be 0.45, 0.33 and 0.48 for Cu, Fe and Zn respectively (Vaughan 1986, Krause 1979, Simsek et al 2000). It was calculated that the ratios of concentrations of Cu, Fe and Zn(CCu: CFe: Cin)in the area of the acupuncture points are pproximately 1: 3.7: 4.3 with a relative uncertainty of 0. 17%o at Jianshi, 1: 3.3: 17.5 with a relative uncertainty of 0.37%o at Tiaokou and 1: 3.5: 17.9 with a relative uncertainty of 0. 14%0Do acupuncture points exist?

Figures 4–6 show spectra collected from and in the vicinity of Jianshi, Tiaokou and Xiajuxu acupuncture points. The parameter Qi was taken to be 0.45, 0.33 and 0.48 for Cu, Fe and Zn respectively (Vaughan 1986, Krause 1979, S¸ims¸ek et al 2000). It was calculated that the ratios of concentrations of Cu, Fe and Zn (CCu:CFe:CZn) in the area of the acupuncture points are approximately 1:3.7:4.3 with a relative uncertainty of 0.17% at Jianshi, 1:3.3:17.5 with a relative uncertainty of 0.37% at Tiaokou and 1:3.5:17.9 with a relative uncertainty of 0.14%
