Expression of pancreatic regenerating gene in lung and intestinal tissue correlates with the severity of disease in rats with acute necrotizing pancreatitis.

Abstract:

:The aim of this study was to investigate the expression pattern of regenerating gene I (Reg I) in the lung and intestinal tissues of rats with acute necrotizing pancreatitis (ANP), as well as the correlation of Reg I expression with lung and intestinal injury. Sprague-Dawley rats were randomly allocated to control (n=40) and ANP (n=80) groups. The rats in the control group received laparotomy only. In the ANP group, 3% sodium taurocholate was injected into the pancreatic duct to develop the ANP model. Reverse transcription-polymerase chain reaction (RT-PCR) was performed to detect the Reg I mRNA levels in the pancreas, intestine and lung. The pathological changes in the pancreas, intestine and lung were observed and the serum amylase levels, the wet/dry weight ratio of the lung and the permeability of the intestinal mucosa were measured. The measured parameters were found to correlate with the Reg I mRNA levels. Reg I mRNA was more highly expressed in the pancreas, intestine and lung in the ANP rats than in the control group. The Reg I expression levels were positively correlated with the pathological scores, serum amylase levels, lung pathological scores, lung tissue wet/dry ratios, intestinal pathological scores and intestinal permeability. The levels of Reg I were increased in the lung and intestinal tissue of the ANP rats and the expression levels of Reg I correlated closely with the severity of the lung and intestinal injury.
