Effect of dalargin on the content of matrix metalloproteinases and tissue inhibitor of metalloproteinases in the colon of mice with experimental ulcerative colitis
 

Background: Ulcerative colitis is a chronic, multifactorial disease, the development of which is stimulated by disturbances in the microbiota of the colon, poor nutrition, an inadequate immune response to pathogenic and commensal microflora, against a background of genetic predisposition, and has important social implications. Increased levels of matrix metalloproteinases in plasma and colon tissue has been shown in ulcerative colitis. Matrix metalloproteinases-2, 9 and tissue inhibitor of metalloproteinases-2 are important in the development of inflammation in the colon. Existing methods of treating ulcerative colitis are not effective enough. Dalargin has a unique combination of effects, that’s why its administration is promising in the treatment of ulcerative colitis. The aim of the study: To investigate dalargin effect on the concentrations of matrix metalloproteinase-2, matrix metalloproteinase-9 and tissue inhibitor of metalloproteinases-2 in the medial colon of mice with experimental ulcerative colitis. Materials and methods: Ulcerative colitis in Balb/C mice was simulated by replacing drinking water with a 5% solution of dextran sodium sulfate in boiled water for 5 days. On the 5th, 7th and 28th days of the experiment, the content of matrix metalloproteinases-2 and 9, tissue inhibitor of metalloproteinases-2, was measured in the homogenate of the medial section of the colon. Dalargin was administered subcutaneously at a dose of 100 mcg/kg for 7 days. Results: An increase in the content of matrix metalloproteinases-2 and 9, as well as tissue inhibitor of metalloproteinases-2, was established in the colon wall of mice with ulcerative colitis on the 5th and 7th days of the experiment. In chronic ulcerative colitis, only tissue inhibitor of metalloproteinases-2 levels were significantly higher than in naive mice. The administration of dalargin caused a decrease in the concentration of matrix metalloproteinases-2 and 9, a tissue inhibitor of metalloproteinases-2, during the acute period of the disease. In chronic ulcerative colitis, administration of dalargin decreased the concentration of tissue inhibitor of metalloproteinases-2 in the wall of the medial section of the colon. Conclusion: Dalargin reduced the content of matrix metalloproteinase-2 and 9 and tissue inhibitor of metalloproteinases-2 in the colon wall of mice with ulcerative colitis on the 5th and 7th days of the experiment. This effect was higher than sulfasalazine one, which is widely used in the ulcerative colitis treatment.
