Abstract:
Objective: To observe the effect of ω-3 fish oil emulsion on the experimental severe acute pancreatitis(SAP)through the morphologic alteration of pancreas,the level of serum amylase(AMS)and the functions of liver and kidney,and explore its possible mechanism. Methods: Rat model of SAP was produced by injecting 5% Sodium Cholate(1 ml/kg)into the biliopancreatic duct.Male Sprague-Dawley rats were randomly divided into 4 groups: normal group(n=6),fish oil emulsion treatment group(FOG,n=18),soybean oil emulsion treatment group(SOG,n=18) and normal sodium treatment group(NSG,n=18).Then fish oil emulsion(FO,10 ml/kg);soybean oil emulsion(SO,10 ml/kg)and normal sodium(NS,10 ml/kg)were intravenously injected respectively 120 minutes.The pancreatitis were confirmed by levels of serum AMS and histopathologic score.ALT,AST,BUN and Cr were tested 24 hours after the treatments.Expressions of IL-1β and IL-10 were tested by ELISA.The activated NF-kappa B was examined in the pancreases. Results: Lower level of serum AMS(P<0.05)and lower histopathology score(P<0.05) appeared in FOG.Compared with NS,FO decreased the levels of serum ALT and BUN significantly (P<0.05).FO significantly attenuated the expression of IL-1β (P<0.05).FO downregulated the activity of NF-kappa B efficiently.Conclusions: By down-regulating the levels of IL-1β together with up-regulating the level of IL-10,FO reduces inflammatory damage at the beginning of AP.
