Modulation of Disorder of InflammatoryAssociated Cytokines with ImmunoSuppressive Agents in Acute Pancreatitis

bjectiveTo observe the effecacy of immunosuppressive agents on modulation of the disorders of inflammatory and antiinflammatory cytokines in acute pancreatitis, and to investigate the mechanism of treatment of acute pancreatitis with immunosuppressive agents. MethodsSD male rats were divided into 6 groups: group 1, the normal control group (n=6); group 2, acute pancreatitis induced by ductual injection of 5%sodium cholate sulfur at the volume of 1.0 ml/kg without treatment (n=8). After the pancreatitis were induced, the rest rats were injected intravenously with 5Fu 40 mg/kg (group 3, n=6); or methylprednisolone 30 mg/kg (group 4, n=6); or cyclophosphamide 20 mg/kg (group 5, n=6); or methotrexate 1.2 mg/kg (group 6, n=6). Twentyfour hours afteroperation, the animals were killed, the blood samples were taken for measurement of TNFα, IL1, IL6 (by bioassay), and IL10, TGFβ (by ELISA) as well as amylase. ResultsThe inflammatory cytokines (TNFα,IL1,IL6 ) and the antiinflammatory cytokines (IL10 and TGFβ), in blood of acute pancreatitis were increased significantly. After treated with immunosuppressive agents, both the inflammatory and antiinflammatory cytokines were decreased in different degrees. Some indexes of the severity of acute pancreatitis, such as amylase and pancreatic weight were improved obviously.ConclusionImmunosuppressive agents can regulate inflammatoryassociated cytokines increased remarkably in the acute pancreatitis. Therefore, improvement of acute pancreatitis can be achieved through rectifying the abnormal immunity and relieving the pathophysiological disorders of the acute pancreatitis by immunosuppressive agents.
