Paper Abstract

The changes in optical transmittance of human adipose cell layers sensitized by indocyanine green (ICG) as a result of photodynamic action were found and studied. It was revealed experimentally that due to the selective action of laser radiation on fat tissue sensitized by ICG the spatial distribution of its optical transmittance becomes more homogeneous. The statistical computer processing of digital images allowed one to estimate tissue optical transmittance, its spatial and temporal distributions. These quantitative estimations correlated well with the visible changes of tissue images. The measurements carried out gave an opportunity to suggest the interpretation of the phenomenon observed.
