Abstract Purpose: To evaluate the oxidative stress, resulting from ischemia and hepatic reperfusion, in mice with non-alcoholic hepatic steatosis and steatohepatitis. Methods: C57BL/6 male mice were used. Part of them were ob/ob mice, and the other part was fed with standard or MCD diets - this last used to develop steatohepatitis. The animals - MCD-I/R, ob/ob-I/R and I/R groups - were submitted to 30 minutes o...
Abstract Purpose: To develop an experimental model of intestinal ischemia and obstruction followed by surgical resection of the damaged segment and reestablishment of intestinal transit, looking at bacterial translocation and survival. Methods: After anesthesia, Wistar rats was subject to laparotomy, intestinal ischemia and obstruction through an ileal ligature 1.5cm of ileum cecal valve; and the mesenteric ves...
ABSTRACT Pancreatic necrosis occurs in 15% of acute pancreatitis. The presence of infection is the most important factor in the evolution of pancreatitis. The diagnosis of infection is still challenging. Mortality in infected necrosis is 20%; in the presence of organic dysfunction, mortality reaches 60%. In the last three decades, there has been a real revolution in the treatment of infected pancreatic necrosis...
PURPOSE: To evaluate intestinal inflammatory and apoptotic processes after intestinal ischemia/reperfusion injury, modulated by pentoxifylline and hypertonic saline.METHODS:It was allocated into four groups (n=6), 24 male Wistar rats (200 to 250g) and submitted to intestinal ischemia for 40 min and reperfusion for 80 min: IR (did not receive any treatment); HS group (Hypertonic Saline, 4ml/kg-IV); PTX group (Pe...
RACIONAL: As lesões do ducto torácico ocasionando quilotórax são pouco freqüentes e ocorrem durante procedimentos torácicos e traumas, tais como esofagectomias, procedimentos cirúrgicos mediastinais e pleuro-pulmonares. A operação está indicada se não houver resolução espontânea. OBJETIVO: Analisar a fístula linfática como complicação de esofagectomias para doenças malignas e benignas. MÉTODOS: Sete doentes com...
