It has been demonstrated that hyperbaric oxygen (HBO) is useful as an adjunctive therapy for Crohn's disease. However, its effects on ulcerative colitis have not been investigated. In the present study, HBO was tested for acetic acid-induced colitis, and antioxidant systems were evaluated to clarify its possible mode of action. Thirty-six Sprague-Dawley(More)
During ischemia-reperfusion, free oxygen radicals which directly affect renal cells may cause delayed graft function. We investigated whether there was a difference regarding antioxidant enzyme content between use of Ringer's lactate (RL) versus University of Wisconsin (UW) perfusion solutions in kidney transplantation. Ischemia was achieved by clamping the(More)
BACKGROUND Oxidative stress is one of the leading causes of cardiovascular morbidity and mortality in chronic kidney disease. Although it is clear that many metabolic abnormalities improve, the effects of kidney transplantation on oxidative state are obscure. METHODS Twenty-three kidney transplant patients were included in the study. Eleven patients (mean(More)
The effect of ischemia-reperfusion (I/R) injury within a transplanted kidney has not been reported on the liver as a remote organ. One hypothesis is that there is no difference between kidney perfusion solutions regarding antioxidants in liver after an I/R injury. We used four pigs with Ringer's lactate (RL); four with university of Wisconsin (UW); and two(More)
BACKGROUND Although intrahepatic arterioportal fistula (APF) due to acquired or congenital causes are infrequent, they are listed among the causes of portal hypertension. PURPOSE The aim of this study was to present the results of intrahepatic APF treatment with embolotherapy in six cases. MATERIAL AND METHODS Transarterial detachable balloon and coil(More)
PURPOSE Lymphocele following kidney transplantation is a well-known complication. We present here the long-term results of percutaneous drainage and ethanol sclerosis in posttransplant lymphoceles. PATIENTS AND METHODS Between October 1988 and September 2003, 18 patients with symptomatic lymphoceles were treated with percutaneous transcatheter ethanol(More)
Multiple endocrine neoplasia type 2B (MEN 2B) is a rare syndrome characterized by medullary thyroid carcinoma (MTC), pheochromocytoma and typical phenotypic features, such as marfanoid habitus, multiple mucosal ganglioneuromas and thickened corneal nerves. Individuals with MEN 2B may develop megacolon and pseudo-obstruction due to intestinal(More)
INTRODUCTION Evaluation of pre- and postoperative serum CEA levels together has seldom been assessed for the prognosis of colorectal cancer (CRC). OBJECTIVE To concurrently evaluate pre- and postoperative CEA as factors of relapse and survival. METHODS The study consisted of 114 patients who had undergone surgery from February 2002 to June 2006 for CRC.(More)
Renal Angiomyolipoma (AML) is a rare benign tumor As it is usually asymptomatic and small, AML sometimes may cause acute abdomen by spontaneous rupture and hemorrhage that may be life threatening in some cases for which surgical management is necessary. A 58-year-old female patient was admitted for right side and right upper abdominal pain, nausea and(More)
OBJECTIVE Colon cancer patients presented with obstruction were known to have worse postoperative morbidity and mortality rates, but conflicting data has been reported in recent years. We aimed to investigate postoperative complication rates, and short and long-term oncological outcomes in patients with colon cancer treated with either emergency surgery due(More)
