Histoarchitectonics features of cow reticulum in normal and traumatic reticulitis

The work describes features of the histological structure of the reticulum wall in dairy cows in the normal condition and in traumatic reticulitis on the ground of the obtained results in comparison with the literature data. The researchers have used a set of classical histological techniques. The histological structure of the reticulum wall of ruminants duplicates the general scheme of the tubular (layered) organ structure. Thus, in the reticulum wall of cows, four layers are distinguished; namely, the mucous membrane, the submucosa, the muscular membrane and the serous membrane, which have a typical histoarchitectonics. In traumatic injury, the histological structure of the reticulum tissues have a clearly expressed specificity and, apparently, depend on the type of reticulitis. When examining the reticulum samples, the nature of the existing damage has made it possible to conclude that there is lamellar and parietal reticulitis. When evaluating histological preparations, signs of chronic nonimmune diffuse epithelial cell granulomatous inflammation have been found at the sites of reticulum damage.
