[A contribution to the study of cardiac lipofuscin fluorescence].
Some characteristics of the fluorescence of cardiac human lipofuscin and, in connection, the acid phosphatase activity were studied. The presence of acid phosphatase reaction product was demonstrated in lipofuscin granulations. Two types of fluorescence spectra with a maximal emission peak at 580 nm. and 600-610 nm. respectively, were obtained. A photodecomposition of average intensity was present and, at same time, shifts the maximal emission peaks were noticed. The data obtained were discussed in relation with the identification of the fluorescent substance.
