Abstract:
Objective To explore the role of nuclear factor-kappa B(NF-?B)in regulating tumor necrosis factor-?(TNF-?)expression in acute pancreatitis (AP)in rats.Methods Sixty-four Wistar rats were randomly divided into two groups:the control group(n=32)and the AP group(n=32).Acute pancreatitis was induced by introperitoneal injection of caerulein,and the animals were killded at 12 hours,24 hours,36 hours,and 72 hours respectively.The activity of NF-?B and expression of TNF-? mRNA in the pancreas were determined by flow cytometry (FCM) method and semi-quantitave RT-PCR analysis,respectively,and the correlation coefficients were analyzed.Results The levels of activated NF-?B protein and TNF-?mRNA were all significantly higher in the AP group than those in the control group at any time point(P
