Abstract:
Objective To examine the effects of carbon dioxide (CO2) pneumoperitoneum on local pancreas pathological changes,serum levels of amylase,IL-1,IL-6,and the positive rate of dissolubility adhesion molecule (CD11a/CD18 and CD11b/CD18) expression in rats with severe acute pancreatitis (SAP). Methods Fifty healthy male Sprague-Dawley (SD) rats were randomly divided into 3 groups:CO2 pneumoperitoneum group (n=20):SAP was induced by injecting 5% sodium taurocholate through retrogradely common biliopancreatic ducts via duodenal papilla,and then CO2 pneumoperitoneum was established at a pressure of 12 mm Hg (1 mm Hg=0.133 kPa) for 30 min; SAP group (n=20):The rats were treated as same as CO2 pneumoperitoneum group,except CO2 pneumoperitoneum; Simple operation group (n=10):Laparotomy was performed and nothing was done to duodenum and pancreas except for moving them softly. The blood samples were collected for examining serum levels of amylase,IL-1,IL-6,and the positive rates of CD11a/CD18 and CD11b/CD18 expression,and histopathologic examination of pancreas was performed. Results Compared with simple operation group,the pancreatic pathologic histology score,serum levels of amylase,IL-1,IL-6,and the positive rates of CD11a/CD18 and CD11b/CD18 expression were significantly higher in CO2 pneumoperitoneum group and SAP group (P=0.000). The levels of IL-1 and IL-6 were significantly lower in CO2 pneumoperitoneum group as compared to SAP group (P=0.000). There was no significant difference between CO2 pneumoperitoneum group and SAP group in pancreatic pathologic histology score (P=0.294),the level of serum amylase (P=0.073),the positive rates of CD11a/CD18 (P=0.155) and CD11b/CD18 expression (P=0.201). Conclusion CO2 pneumoperitoneum has inhibitory effect on the levels of IL-1 and IL-6,rather than the positive rates of CD11a/CD18 and CD11b/CD18 expression in SD rats with SAP.
