A precise and reproducible method of quantitative determination of the photosensitizer Photolon® in hepatic tissue of the liver of rats by means of spectrophotometric assay with preliminary chemical extraction was developed for validation of the method of in vivo measurement of a fluorescent signal of the tissue after injection of the photosensitizer. Using the ex vivo spectrophotometric technique a quantitative assessment of the results of spectrofluorescent measurements performed in vivo was made. A high correlation (R2=0,99) between results estimated by two different techniques was shown. Also validity of the simple and easy-to-use method of in vivo fluorescence intensity measurements for the investigation of the pharmacokinetics and biodistribution of different photosensitizers was demonstrated.
