Background:Damage of intestinal mucosal barrier is a key factor in the development and progress of acute pancreatitis(AP),and is closely related with the prognosis of the disease. Aims:To investigate the protective effect and possible mechanism of mucoprotective agent teprenone on intestinal mucosal barrier in rats with experimental AP. Methods:Forty-five adult male Sprague-Dawley rats were randomly divided into normal control group(n = 5),AP model group(n = 20)and teprenone treated group(n = 20). AP model was established by subcutaneous injection of cerulein at abdominal wall. Rats in treated group were intervened with teprenone intragastrically before and after model establishment. ELISA was used for measurement of serum interleukin-1(IL-1),IL-6,tumor necrosis factor-α(TNF-α)and amylase;histopathological and ultrastructural changes of small intestinal mucosa were observed by light microscope and transmission electron microscope;Western blotting was used to detect the expressions of tight junction protein occludin and ZO-1. Results:Serum levels of IL-1,IL-6,TNF-α and amylase in AP model group were significantly higher than those in normal control group(P < 0. 05),accompanied by necrosis and exfoliation of small intestinal villus,widening of intercellular tight junctions and downregulation of occludin and ZO-1 expression. While in teprenone treated group,serum levels of proinflammatory cytokines and amylase were significantly decreased as compared with AP model group(P < 0. 05),the villus of small intestine remained intact,and dense tight junctions were observed. Expressions of occludin and ZO-1 in teprenone treated group were upregulated. Conclusions:Teprenone may protect against intestinal mucosal barrier injury in AP model rats by upregulating tight junction protein expression.
