It has been shown that oxygen free radicals have an important role in development of pancreatitis and its complications. Antioxidant, anti-inflammatory, anti-hepatotoxicity and gastroprotective properties of <em>Cichorium intybus </em>L. suggest that this plant may have beneficial effects in the management of acute pancreatitis.</p> <p><strong>Methods: </strong>Five intraperitoneal (i.p.) injection of cerulean (50 &mu;g/ kg at 1 h intervals) in mice resulted in acute pancreatitis, which was characterized by edema, neutrophil infiltration, as well as increases in the serum levels of amylase and lipase in comparison to normal mice. Different doses of <em>C. intybus </em>root (CRE) and aerial parts hydroalcoholic extract (CAPE) orally (50, 100, 200 mg/kg) and intraperitoneally (50, 100, 200 mg/kg) were administrated 1.0 and 0.5 h respectively before pancreatitis induction on separate groups of male mice (<em>n</em>=6). Control groups treated with normal saline (5 ml/ kg) similarly.</p> <p><strong>Results: </strong>Both extracts in greater test doses (100 mg/kg and 200 mg/kg, i.p.) were effective to decrease amylase (23-36%) and lipase (27-35%) levels. In oral route, the dose of 200 mg/ kg showed a significant decrease in levels of amylase (16%) and lipase (24%) activity while the greatest dose (200 mg/kg, i.p.) was only effective to diminish inflammatory features like edema and leukocyte infiltration in pancreatitis tissue (<em>P</em>&lt;0.01). Vacuolization was not significantly reduced in extracts treated groups.</p> <p><strong>Conclusions: </strong>These data suggest that <em>C. intybus </em>hydroalcoholic extracts were effective to protect against experimental acute pancreatitis and the efficacy was partly dependent to the dose and was more significant after parenteral administration.</p> <strong>Keywords: </strong>Animal model, <em>Cichorium intybus </em>L., inflammation, pancreatitis, plant e xtracts, preventive therapyhttp://ijpm.mui.ac.ir/index.php/ijpm/article/view/352http://ijpm.mui.ac.ir/index.php/ijpm/article/download/352/516
