title: The importance of laser-biophotometry in vivo in medicine.
abstract: Infrared laser biophotometry limits to a relatively strait spectrum (0.85-0.89 mkm) and it is based on the absorption, dispersion and reflexion phenomena from the tissues. It was taken a study group of 180 people (students and other categories of people considered healthy). The determined medium reflexion coefficient in infrared in the intact tissues is an index with medium values (between 55.7-68+/-2.1 milliwatts), stable in time. The individual variations of the medium coefficient of reflexion in infrared (MCR IR) for the intact tissues do not exceed 3+/-2.1 milliwatts. The MCR IR values determined for intact tissues will be taken as reference point in the determination of the MCR IR for pathologically modified tissues (edema, hematoma, abscess) in the next part of the study. The obtained results allow the use of Laser-biophotometry in vivo method in the evaluation and observation of the pathological processes accompanied by water retention in the organism, differentiation of the processes concerning fat accumulation (obesity, metabolic X syndrome, etc.). Absorption particularities of radiation in Infrared, observed during this study, suggest physiotherapeutic factor graduation determined by individual particularities of the organism: the pigmentation degree of the skin tissue and the tissue structure (stroma density).
