[Cytofluorometric analysis of small intensively fluorescent atrial cells at various stages of postnatal ontogenesis].
The number and fluorescence intensity of small intensely fluorescent (SIF) cells in the nerve ganglia of the rat atria were determined after the treatment, using modified Falk's method. The animals were 1, 7, 14, 28 days and 30 months of age. Similar changes were found in the amount of SIF cells and fluorophore content in all the atrial regions. A marked increase in the number of SIF cells and maximum values were determined between the second and fourth week after birth. The first two weeks of age corresponded to the decrease and the forth week to the increase in SIF cells fluorescent intensity. The data of the investigation made it possible to suggest the connection between principal stages of SIF cell pool formation and processes of autonomic ganglia innervation development.
