[Tissue autofluorescence damping mechanisms, sensitized by tumorotrophic dyes].

Using an automated laser-fiber spectrofluorimeter, the fluorescence spectra of normal and malignant tissues sensibilized by chlorin e6 and flurenate in vivo and ex vivo were studied. A quenching of intrinsic fluorescence of sensibilized tissues was found, which was more evident in the affected regions. The observed effect is related to electron excitation energy transfer from endogenous fluorophores to the photosensitizers administered.

[Features of the effect of ukrinol on the phospholipid spectrum in white rat whole blood and erythrocyte membranes in a chronic experiment].

Qualitative composition and quantitative changes of phospholipids of the whole blood and membranes of white rats erythrocytes have been studied as affected by ukrinol. Regularities in the change of phylogenetically stabilized phospholipid-phospholipid relations in the studied biological systems have been found under the long-term effect of ukrinol on the organism. The ways of normalizing of the disturbed phospholipid metabolism under ukrinol intoxication are discussed.
