title: [Modeling damage of the mucous membrane of the gastrointestinal tract in rats].
abstract: We studied the effect of NSAIDs on the stomach lining and intestines. Animals received the selective and nonselective NSAIDs. Revision of the abdominal cavity was performed after 24 hours and 14 days. In the mucosa was determined by the levels of prostaglandins and measured the index of damage. Lowering the synthesis of PG in the mucosa of the gastrointestinal tract contributes to the formation damage. After 24 hours when receiving non-selective COX inhibitors and selective inhibitors of COX-2 revealed the presence of mucous membrane lesions that are smaller than in groups of animals treated with selective NSAIDs. After 14 days of reception remains a low level of GHGs in the group of animals treated with nonselective NSAIDs. Visually mucosal damage are insignificant, but in the submucosal layer preserved microcirculatory blood flow disturbances.
