Öğe Erythrocyte and plasma superoxide dismutase activities in acute appendicitis(1998) Koltuksuz U.; Uz E.; Gursoy H.; Demircan M.; Aydinc M.; Mutus M.; Cetin S.Although the role of oxygen free radicals in many inflammatory diseases has been well known, it has not been thoroughly investigated in the inflammatory diseases, of the abdomen. In order to investigate the possible role of oxygen free radicals in the mechanism of progression following the onset of inflammation, blood samples from 18 patients diagnosed as acute appendicitis and 10 healthy children as controls were collected. After plasma and erythrocytes of the blood samples were separated, superoxide dismutase (SOD) activities were measured in these compartments. Additionally, the patients with appendicitis were divided into perforated (n=8), and nonperforated (n=10) subgroups, according to intraoperative examination findings and histopathological classification. SOD activities were compared statistically between these two groups, and the control group. A significant difference in SOD activity between perforated and nonperforated appendicitis in both plasma and erythrocyte was observed (plasma: 4.2±1.7 and 2.0±0.7 U/ml, p<0.05; erythrocyte: 1690.7±799.6 and 1104.2±225.1 U/grHb, p<0.05). The difference between the nonperforated group and control group was not significant, whereas there was a significant difference between the perforated and control groups (plasma: 4.2±1.7 and 2.6±0.9 U/ml, p<0.05; erythrocyte: 1690.7±799.6 and 1148.8±152.2 U/grHb, p<0.05). According to these results, we may speculate that free oxygen radicals released from polymorphonuclear leucocytes following an inflammatory condition may play an important role in the progression of acute appendicitis with the contribution of some other possible factors.Öğe Injuries of large vessels in high stage neuroblastoma surgery. A case report(1999) Koltuksuz U.; Gürsoy M.H.; Aydinç M.; Özgen Ü.; Ege E.; Mutus M.Complete resection of the primary lesion in stage III neuroblastoma improves survival. Neuroblastoma has a tendency towards surrounding and infiltrating the large vessels, leading to injuries during tumor resection. We operated on a stage Ill neuroblastoma, which resulted in the right and left common iliac artery and vein damage. The right common iliac artery and, veins were repaired by end to end anastomosis. There was a long gap between the two ends of the left common iliac artery and it was repaired using a mesenteric vein (marginal vein of the colon) graft. Digital subtraction angiography performed 6 months after the operation did not reveal any stenosis or aneurysmatic changes in the anastomoses. We conclude that short segments of large vessels may be sacrificed during the resection of neuroblastomas invading the vessel wall, and the resulting defects may be repaired by end to end anastomosis, or even by substituting mesenteric vein grafts, for the purpose of total or near total removal.Öğe A sporadic case with fraser syndrome with cleft lip and palate(2001) Evereklioglu C.; Er H.; Cokkeser Y.; Bayramlar H.; Mutus M.[No abstract available]
