Resveratrol ameliorates the deleterious effect of severe acute pancreatitis.

Resveratrol (RES) is a traditional Chinese herbal medicine having anti-inflammatory properties. We sought to explore the role of RES in intestinal injury during severe acute pancreatitis (SAP) in a rat model study. For this purpose, RES-treated and sham-operated (SO) SAP rat models were established, and SAP was induced in rats by injecting 4% sodium taurocholate into the biliary-pancreatic duct. In the RES group, RES was infused intravenously immediately after the SAP induction in rats; SO group served as controls. Histopathological analysis, determination of tissue levels of superoxide dismutase (SOD) and malondialdehyde (MDA) and serum levels of TNF-α as well as ICAM-1 and VCAM-1 expression were carried out at 3, 6, and 12 h following SAP induction. The data show that following SAP induction, SOD levels decreased and MDA levels increased along with ICAM-1 and VCAM-1 expression in the intestine. Serum TNF-α levels increased in the SAP group. Importantly, RES treatment significantly reversed all the pathological changes. In conclusion, this study confirmed the anti-inflammatory properties of RES and demonstrated the prevention of injury to the intestinal barrier in the rat SAP model.
