[Hematoporphyrin derivative-induced tumor fluorescence]

Detection of HpD-sensitized tumour was successful by use of HBO 200 mercury lamp, Argon ion laser, as well as for N2-pumped dye laser. After 20 hours period of HpD application the localization of the Ehrlich ascites tumour in mice was identified macroscopically and by spectroscopy. To exclude red emissions of detection sources the use of dye lasers is recommend.
