[Effects of light-activated hematoporphyrin derivative on nucleotides and experimental tumors]. / Vozdeistvie aktivirovannogo svetom proizvodnogo gematoporfirina na nukleotidy i éksperimental'nye opukholi.

The data on the photodamage of biomolecules and experimental tumours by a hematoporphyrin derivative activated with laser radiation are presented. Inhibition of the tumour growth and prolongation of the life-span of treated tumour-bearing animals are observed.

[Molecular biological mechanisms of photodynamic therapy]. / Molekuliarno-biologicheskie mekhanizmy fotodinamicheskoi terapii.

The biological mechanisms of photodynamic therapy, a new approach to the treatment of malignant lesions, are considered. The data on chemical composition of hematoporphyrin derivative are given, the photophysical and photochemical reactions caused by photosensitizer distribution in organism and cell, as well mechanisms of photodestruction of cells and cell organelles.
