Polypropylene mesh is an effective and widely used material in repairing abdominal wall defects, but it causes dense adhesions when in contact with abdominal viscera directly. As a consequence of this process intestinal obstruction and enterocutaneous fistula may develop. The purpose of the present study was to determine whether Seprafilm®, a bioresorbable translucent membrane, reduces abdominal visceral adhesions to polypropylene mesh and whether Seprafilm® has any effects on peritoneal tissue ...

It has been known that contrast medium may cause contrast-induced nephropathy in risk groups. This study sought to establish possible effects of ionic high-osmolar contrast medium administration with or without antecedent cisplatin treatment on oxidant/antioxidant status in rat kidney tissues, as well as to investigate a possible protective role of antioxidant ascorbic acid in this regard. Thirty-five female, 14-week-old Wistar-albino rats were used in this study. They were divided into five groups ...

Pneumatosis cystoides intestinalis is a rarely seen disease characterized by cysts filled with multiple gases in the wall of the small or large intestine. Many factors have been suggested in the etiology and pathogenesis, including peptic ulcer, pyloric stenosis, and endoscopic trauma. Because various clinical characteristics and symptoms are observed together, diagnosis is generally difficult. It may be a cause of free air observed on direct radiographs. Treatment is directed at the cause and although ...

Systemic sclerosis (SSc) is an autoimmune chronic fibrotic disorder. Urotensin II (U-II) is predominantly a vasoactive peptide with fibrotic and prothrombotic features. Like endothelin-1 (ET-1), U-II could play an important role in SSc pathogenesis. We evaluated the possible role of the U-II gene polymorphisms (Thr21Met and Ser89Asn) in the genetic susceptibility to SSc in a Turkish population.A total of 189 patients with SSc and 205 healthy controls were enrolled in our study. We analyzed the genotype ...
