[Characteristics of "photo depletion" of the green fluorescence of tumor cells].
The green (oxidized flavoproteins) fluorescence intensity was found to increase during investigation of NADH and oxidized flavoproteins fluorescence with the use of optimal excitation of different fluorescence bands. This effect was observed under excitation with blue light (436 nm). It is suggested that in some malignant cells, the structure of flavoproteins (probably of mitochondrial ones) may be altered in the way of increasing the quantum yield under the action of light irradiation.
