In the article, conducting experimental studies on white rats of the Wistar line, we considered the effect of NO, as a mediator of inflammation in experimental colon ulcers, on smooth muscles (GM) of the stomach (G), duodenum (D) and colon (C). The experiments were carried out on white rats, of both sexes, weighing 180-220 g (average weight 200 g). The keeping of animals in the vivarium was in accordance with the sanitary rules. All experiments were carried out in accordance with the rules of humane treatment of animals. All manipulations were performed under general anesthesia in compliance with aseptic and antiseptic requirements.

To determine the level of NO in the blood serum, the nitrite/nitrate (NOx) method was used. Experimental colitis was induced by oral administration of 5% Dextran sodium sulfate (DSS) polymer solution of dactran sodium sulfate. To inhibit NO synthase, the animals were injected intraperitoneally with 1.0 ml of a 1% aqueous solution of Methylene coeruleus. a high level of NO content, due to the increased activity of the inducible form of NO-synthase, has not only a toxic effect on the mucous membrane of the colon, with a simultaneous relaxing effect on the circular and contraction of the longitudinal layer of the GM G, pyloric canal and D. The nature of the effect on all these parts of the gastroduodenal zone has a different degree of relaxation, which is the result of specific tissue homeostasis.
