Pulmonary complications are frequent during acute pancreatitis (AP). We investigate the effects of N-acetylcysteine (NAC) on lung injury in mild and severe AP. ANIMALS AND TREATMENT: Mild and severe AP was induced in rats by bile-pancreatic duct obstruction (BPDO) and infusion of 3.5 % sodium taurocholate (NaTc) into the bile-pancreatic duct, respectively. NAC (50 mg/kg) was given 1 h before and 1 h after AP. ⋯ Although NAC treatment down-regulated inflammatory mediators in lungs during AP it did not prevent leukocyte infiltration, which could be responsible for maintaining the lung injury. As a result, NAC aggravated the lung damage in severe AP and failed to exert beneficial effects in the mild disease model.
