It has been established that features of modern diet might be considered as a possible source of inflammatory diseases of gastrointestinal tract. Particular attention is paid to the role of different food additives in the development of intestinal inflammation, including the food additive E407, known as carrageenan. A model of chronic carrageenan-induced gastroenterocolitis of moderate severity has been elaborated, which allows us to study carrageenan-induced intestinal inflammation. In

The female Wistar rats have been used for the experiment. Chronic carrageenan-induced gastroenterocolitis has been reproduced by the free access of animals to 1% solution of carrageenan in drinking water. Laboratory animals have been divided into 3 groups. Group № 1 consisted of experimental animals, who consumed food additive carrageenan during 2 weeks and group № 2 included experimental animals, who consumed food additive carrageenan during 4 weeks. Group № 3 consisted of intact healthy animals. The development of gastroenterocolitis has been proved morphologically and biochemically. Manipulations with animals have been carried out in accordance with the provisions of the European Convention for the Protection of Vertebrate Animals used for Experimental and other Scientific Purposes (Strasbourg, 1986). It has been established that the disease has been associated with dysproteinemia. The level of α1-globulins increased after 2 weeks of carrageenan consumption and has been normalized in animals, who consumed carrageenan during 4 weeks. The similar changes have been observed for α2-globulins level. It could be explained by production of acute phase proteins, such as α1-acid glycoprotein, C-reactive protein, fibrinogen, α2-macroglobulin, ceruloplasmin, etc. The intake of carrageenan also caused hypergammaglobulinemia that was more significant in animals of the 2nd group.
