Résumé
Objective To investigate the relationship between inducible nitric oxide synthase(iNOS)mRNA expression of pancreatic tissues and intestinal permeability,and the effect of salviae miltiorrhizae on the change in gut permeability in rats with severe acute pancreatitis(SAP).Methods All rats were randomly divided into three groups:Sham operation(group C,n=15),SAP group(group SAP,n=15),and salviae miltiorrhizae therapeutic group(group T,n=15).At 24h After operation,the iNOSmRNA expressions of pancreas were determined by in situ hybridization(ISH),and blood amylase(AMY),nitric oxide(NO) and lipopolysaccharide(LPS) were examined.The histopathologic changes of pancreas and ileum were observed.Intestinal permeability was measured by means of albumin clearance(AC)of 125I-labeled rat serum albumin.Results The iNOSmRNA expressions of pancreas in group SAP were markedly increased in comparison with group T(P
Résumé
Objective To study the significance of change of high mobility group box 1(HMGB1)level of pancreas in acute necrotizing pancreatitis(ANP)in rats.Methods ANP model was induced by retrograde injection of sodium taurocholate in pancreatic duct.Animals were divided randomly into three groups:control group,ANP group,and sodium butyrate treatment group(treatment group).The serum levels of TNF-? and IL-1? were measured by ELISA.The HMGB1 mRNA level of pancreas was detected by RT-PCR.Results The serum levels of TNF-? and IL-1? were quickly increased after the model was induced,and reached a peak at 6h,but decreased at 12h.The HMGB1 mRNA level of pancreas was increased significantly at 12h,and maintained to 24h.Whereas in treatment group,the HMGB1 level of pancreas was lower than ANP group(P
