ABSTRACT
Objective To investigate the role of octabedral montone on ileum NF-κB activation in rats with acute necrotizing pancreatitis (ANP).Methods 120 SD rats were randomly divided into sham-operation group(A),ANP group(B),mosapride treatment group(C),montone treatment group(D),montone and mosapride treatment group (E).Retrograde pancreatic duct injection of sodium taurocholate was used to establish ANP models,octahedral montone and mosapride were given by intragastric feeding 30 min before ANP model induction,group A was injected NS after opening the abdomen.Pancreatic tissue injury was evaluated;the serum level of TNF-a and IL-1 was determined;the ultrastructural changes of the ileum was observed.The expression of NF-κB in the ileum mucosa was detemined by immunohistochemistry.The expression of IκBa protein in the ileum tissue was determined by Western blotting.Results Compared with group A,pancreatic tissue injury was more severe in group B,and serum level of TNF-a and IL-1 was much higher in group B [(36.79±1.14) vs (9.00±0.01 )pg/ml,(25.17±1.93) vs (3.45±0.11)ng/ml,P<0.05];the height of the villi was significantly lower[(0.25±0.22 )×10~(-6) mvs(1.50±0.33 )×10~(-6) m,P<0.05)],the index of columnar cell was significantly lower[(2.40±1.65)×10~(-6)m vs (13.5±4.28)×10~6/m,P<0.05)];the expressions of NF-κB was significantly eleveted(6.92±1.54vs 1.28±0.29,P<0.05),the expressions of IκBa protein was significantly decreased(3.30±1.99 vs 24.32±1.93).There was no significant difference between group D and C.The serum level of TNF-a and IL-1[(30.57±0.39)pg/ml and(13.45±1.26)ng/ml],the height of the villi and the index of columnar cell[(1.05±0.28)×10~(-6)m and(10.10±2.50)×10~6/m]and the expressions of NF-κB(4.3240±1.5657)and IκBa(15.987±1.262)was statistically significantly different compared with those of the ANP group(P<0.05).Conclusions Octahedral montone and mosapride could decrease the NF-κB activation and ameliorate the inflammation of ileum and pancreas during the course of ANP.
