title: [Serotonin and neurotensin-containing cells in the mucosa of the alimentary tract].
abstract: Localization of serotonin (5-OT)- and neurotensin (NT)-containing cells in the tunica mucosa of the gastric antral part and the duodenum of the rat and chick has been revealed by means of the immunofluorescent method and the method with application of the peroxidase-antiperoxidase complex. For immune-histochemical revealing of biologically active substances in endocrine cells Sovient antisera are used for the first time. Experiments are performed on injection of antiserotonin serum of various dosage into the rat blood bed. The reaction of serotonin-containing cells of the gastric antral part tunical mucosa and those of the duodenum to changes in serotonin concentration in blood serum is demonstrated.
