Abstract
It is well known that sulphophthalocyanine derivatives under laser irradiation induce photochemical reaction of II type with generation of cytotoxic agent - singlet oxygen. The combination of phthalocyanine and exogenic reductant - sodium ascorbate may also induce other reactions, involving the formation of free radicals, and thus intensify the antitumor effect. To improve the results of PDT we used the additional injection of sodium ascorbate, the hyperbaric oxygenation and different regimes of laser irradiation. We conducted the experimental study on 100 white mice with Erlich carcinoma. Macroscopic and microscopic data showed that sodium ascorbate significantly increases the effect of PDT in comparison with control group due to the higher tumor damage, vascular alterations, inhibition of cell proliferation and stimulation of antitumor desmoplastic reaction.
