background: liver ischemic insults are important sources of liver injuries leading to production of reactive oxygen species (ros) and mediating liver cell injury. glutathione mediated mechanisms are among the most important defense mechanisms of the liver; n-acetylcysteine (nac) provides cysteine for glutathione defense mechanisms. patients undergoing cardiac surgery are at increased risk of li...

Introduction: Colon adenocarcinoma is one of the foremost causes of cancer mortality. Oral metastasis of colon adenocarcinoma is, however, rare and indicates an end-stage disease process.   Case Report: We report a case of a 69-year-old female with a gingival mass diagnosed with colon adenocarcinoma and liver metastasis after one year. A swelli...

5 cases of hydatid cysts of the heart underwent successful enucleation or removal of the cysts with the aid of cardiopulmonary bypass are being reported. their location, signs, symptoms, diagnostic procedures and consequences are being discussed. clinical, radiologic, electrocardiographic and coronary angiographic findings all confirmed the diagnosis. ah the patients had uneventful postoperativ...

conclusions systemic arterial leukocyte filtration reduces the intubation time but has no other beneficial effect on the outcome of patients undergoing cabg or valve surgery. results the postoperative intubation time was significantly shorter in patients with leukocyte filters (0.014). there was no significant difference between two groups regarding other outcome relatedvariables. patients and ...

Inflammatory bowel disease (IBD) is a chronic relapsing and remitting inflammatory disorder of the small intestine colon. IBD includes ulcerative colitis (UC) Crohn’s (CD), it main reason for expansion colon cancer, referred to as colitis-associated cancer (CAC). Oral colon-targeted microsphere based drug delivery system containing sulfasalazine was prepared, optimized characterized. The micros...

conclusions there was no difference in clinical outcome after cardiac surgery when we administered an additional dose of methylprednisolone compared to a single dose of methylprednisolone. patients and methods sixty pediatric patients (age < 5years) undergoing cardiopulmonary bypass surgery between september 2011-2012 at imam reza hospital-mashhad were randomly assigned to receive preoperative ...

OBJECTIVE Previous work has found cerebral oxygen extraction to decrease during hypothermic cardiopulmonary bypass in children. To elucidate cardiopulmonary bypass factors controlling cerebral oxygen extraction, we examined the effect of perfusate temperature, pump flow rate, and hematocrit value on cerebral hemoglobin-oxygen saturation as measured by near infrared spectroscopy. METHODS Forty...

Abstract Background Bouveret syndrome is a rare form of gastric outlet obstruction due to gallstone ileus. It caused by passage large stone from the gallbladder into duodenum via bilio-duodenal fistula causing obstruction. was first described Leon in 1896 and occurs most commonly elderly patients with higher incidence women. In classic syndrome, itself becomes impacted intestinal lumen. A case ...
