✦ Synopsis


Illumination of hematoporphyrin diacetate (HP-Diac) and hematoporphyrin (HP) in phosphate-buffered solutions causes the formation of a stable photoproduct absorbing at 636 nm. Simultaneously the photo-oxidation of HP-Diac and HP takes place. These phototransformations depend on the illumination dose and the concentration of the HP-Diac or HP solution, and cause qualitatively the same spectral changes independently of the light source used.

Different fluorescence spectra are observed on preferential excitation of monomer and aggregate species of hematoporphyrin and hematoporphyrindiacetate, respectively. From these measurements we obtain the fluorescence spectrum of aggregate species in buffer solution, which shows two maxima, at 628 n

The excited singlet and triplet absorption spectra of hematoporphyrin diacetate are presented. Extinction coefficients in the spectral range 420-700 nm are estimated. Two possible mechanisms of step excitation are proposed. The maximal stepexcitation efficiency is achieved at 450 nm.

A linear relationship was demonstrated between the reciprocals of the concentration of free hematoporphyrin and the moles of hematoporphyrin taken up by the platelet in the dark. Radiated platelets took up more hematoporphyrin than did controls; this increase in uptake was accounted for by the movem
