|Abstract:||Lung complications are the most common cause of death in patients with acute pancreatitis. In this study, we investigated how induction of mild acute pancreatitis could modify the course of lung inflammation, eventually, induced by a severe acute pancreatitis in rats. A severe and a mild forms of an experimental acute pancreatitis were respectively established by intra-ductal administration of sodium taurocholate to final dose of 50 g/kg body wt. and intra-peritoneal injection of caerulein to supramaximal dose of 40 g/kg body wt. We observed reduced levels of thiobarbiturate acid reacting substances when severe pancreatitis was preceded by the induction of mild pancreatitis. Moreover, mRNAs expression of both HSP-70 and Mn-SOD was increased in the lung. By contrast, the level of glutathione was reduced, but no change in the infiltration of neutrophils was observed. Therefore, we conclude that during the course of pancreatitis and its related lung inflammation, the pulmonary cells response involved in the expression of different protective proteins, including HSP-70 and Mn-SOD, which possibly improves the defensive mechanisms against inflammation in lung cells.|
