Paper Abstract

The possibility of laser fluorescence diagnosis of malignant tumors with the aid of multifrequency (355, 440, 446, 532, 660, 670 nm) solid state YAG:Nd laser and the rise in accuracy of this method were discussed. Permitted for clinical employment sodium fluorescein has been used as human tumor-localizing dye. The fluorescence spectra of sodium fluorescein containing human normal tissue and breast, stomach, intestine, skin cancer during excitation with the third harmonics of YAG:Nd and with help of multichannel fiber-optic spectrofluorometer were studied. The contrast accumulation of the dye in tumors of different localization was investigated. The fluorescence spectra of chlorine e6, containing animal tissues at different excitation wavelength (355, 532 and 660 nm) were obtained. The pharmacokinetic behavior of chlorine e6, containing different organs and tumor tissues of rats, infected with Sarcoma-45 has been investigated.
