Abstract

The localization and quantitative distribution of the biogenic monoamines of the intestinal tract has been studied in Locusta migratoria, Helix pomatia and Cyprinus carpio with morphological and biochemical methods. Electron microscopically dense-core vesicles of aminergic character were found in the varicose nerve fibres located in the intestinal muscles of all three animal species. Intensive green fluorescence characteristic of catecholamines was detectable in both the varicose nerve fibres and perikarya. Using a fluorimetric method the quantity of biogenic monoamines was measured in the gastrointestinal tract of all three species. The amount of adrenaline and noradrenaline was rather low: 0.03-0.29 μg/g. The dopamine content reached the value of 6 μg/g in the locust gut, and a significant amount of serotonin was present in the intestinal tract of all three species: 1.00-2.59 μg/g. Compared to the adrenaline and noradrenaline serotonin proved to be higher by more than one order in each case. On the basis of morphological and biochemical results the authors suggest that biogenic monoamines are involved in the regulation of the gut muscle functioning both in the form of transmitters as well as neurohormones.
