Paper Abstract

Oxygen supply is the most important requirement of type II photodynamic reactions. Prerequisite in photodynamic tumor therapy is an intact tumor blood flow during irradiation. Most photosensitizers destroy tumor vessels due to accumulation in endothelial cells. As a prerequisite to develop novel photosensitizing drugs an in-vivo test system is required to quantitatively assess for inertness of those sensitizers to the blood supply. We adapted and further developed a system capable of measuring the relative oxygen supply to heterotransplanted tumors on the yolk sac membrane (YSM) of fertilized chicken eggs.
