[Histofluorescent study of catecholaminergic cells of the mammalian autonomic nervous system].
The structure, distribution and fluorescent properties of catecholaminergic cells in the peritoneal sympathetic ganglia and in the intramural plexus of the digestive tract, in the heart and aorta have been studied in white rats (Wistar strain), in dogs, cats and in man. It has been stated that the sympathetic ganglia and the intramural plexus have different monoaminergic cells: large adrenergic (sympathetic) neurons and small intensely fluorescent (SIF) cells. In young and mature cells, mainly catecholamines are accumulated in their cytoplasm. With age, in some cells described above serotonine predominate. Perikaryon of the large adrenergic neurons possesses a rather high monoaminoxidase activity and a low degree of fluorescence. Their processes running towards the internal organs and vessels, on the contrary, are characterized by a high specific fluorescence. These neurons make the base of the sympathetic ganglia. In the intramural plexus similar neurons are rarly found and in small number (1-2 per 1 cm2 in the myenteric plexus). Two types of cells can be mentioned among SIF-cells-chromaffin (SIF-cells of the first type) and interneurons (SIF-cells of the second type): they differ in their structure, arrangement, connections and fluorescence properties. Physiological role of the cells is discussed.
