[Fluorescence spectra of the SIF cells in rat neuroganglia].
The spectral curves of emission of paraform-induced fluorophores in small, intensely fluorescent (SIF) cells in lumbar ganglia of the sympathetic trunk and in the major pelvic ganglion were compared with the fluorescence spectra of lipofuscin granules in the perikaryons of the neurons of the vagus inferior ganglion. As a rule, the fluorescence spectra of SIF cells correlate with the content in them of catecholamines. The spectral characteristics of fluorophores of so-called "yellow" SIF cells have much in common with the fluorescence spectra of lipofuscin granules. Apparently, in some of cases small cells containing lipofuscin may be identified as "yellow" SIF cells.
