Abstract
We describe here the study of biomedical measurements utilizing spectral analysis of ultraweak photon emission from human blood plasma and urine. It has been suggested that detection of ultraweak photon emission intensity of plasma, urine or other kind of biological materials provides information regarding to physiological condition of vital system; especially it reflects the states of oxidative stress of the body. In this experiment, we characterized emission spectra of plasma and urine, and examined the comparison between those from hemodialysis patients (HD) and normal subjects. In addition, the spectral properties of isolated serum lipoprotein were studied. Spectral analysis was carried out by the filter-differential type biophoton spectral analyzer covering the wavelength region of 450-850nm.
In the experimental results, spectral change of normal plasma was observed at the auto-oxidation process, with prominent emission peak around 670nm. Difference of spectral distribution between HD and normal subjects was observed at 400-700nm region, and significant difference appeared at 600-700nm region. It is suspected that this wavelength region represents the states of oxidative stress of the body significantly.
