Malt - система слизистой оболочки желудочно-кишечного тракта

The mucous membrane of the gastrointestinal tract is an extensive information and communication system that quickly reacts to both external and internal factors of the body, ensuring the maintenance of homeostasis of tissue and blood. The aim of the study was to determine the factors that ensure the appearance of an autoimmune component in damage to the pancreas in rats. Material: manipulations were performed on white Wistar rats weighing 190,0-230,0.Immunization of animals was carried out according to the standard scheme. There were 4 intraperitoneal injections of 2 ml of pancreatic tissue homogenate. Total antibodies (at) to parietal cells (PC) (Parietal Cell antibodies, IgG, IgA, IgM) were determined in plasma by enzyme immunoassay. The animals were divided into one control group and five experimental groups (6 groups of 5 rats in total). Experimental groups: 1st-immunization of intact animals (IM) according to the above scheme. 2nd-acute pancreatitis (AP); 3rd group AP+ IM; 4th-chronic pancreatitis (CP); 5th group-CP+IM. With AP and CP, there is an autoimmune component that interferes with the restoration of damaged pancreatic tissue. Experimental studies have shown that the presence of acute inflammation, accompanied by full blood vessels, hyperemia, edema, hypoxia, necrosis, death of a large number of cells, the release of cellular elements that are endogenous antigens. Inflammation of the pancreas stimulates the immune system of the gastrointestinal tract. In addition, factors contributing to the development of an autoimmune reaction are: alcohol, infection: bacterial, viral and/or parasitic.
