| Popis: | The neuronal composition of the intramural plexuses of the gastro-intestinal tract in cats was studied by luminescence microscopy. The intramural ganglia were found to contain three populations of neurons. The neurons of the first population showed no specific catecholamine fluorescence. Those of the second population had fluorescence of the perikaryon and processes. The perikarya of the third neuron population were not fluorescent but adrenergic synapses were seen on their surface. Intraperitoneal injection of exogenous noradrenalin (1 mg) led to an increase in the number of neurons of the third population with specific fluorescence. On this basis it was concluded that as well as parasympathetic intramural neurons the intramural ganglia of the gastro-intestinal tract also contain sympathetic cells, most of which exhibit specific fluorescence only after their mediator content has been artificially increased. |
