Gamma radiation is known to cause serious damage in the brain, and many agents have been used for neuroprotection. In this study, lipid peroxidation levels and histopathological changes in brain tissues of whole-body irradiated rats with likely radiation injury were compared to those with melatonin and vitamin E protection. Forty rats in four equal groups(More)
We aim to evaluate the mechanisms responsible for complications during trigeminal rhizotomy via foramen ovale puncture. Ten dry skulls and 10 skull-base specimens were investigated in the present study. In cadaveric skull-base specimens, the anatomical relationships between the foramen ovale, mandibular nerve and Gasserian ganglion and the surrounding(More)
In this study, we aimed to investigate the biochemical and histopathological protective effects of octreotide and melatonin in an experimental model of spinal cord injury. Fifty- six male albino Wistar rats were divided into four groups. Rats in the G1 group (n=7; control group) did not undergo any treatment except for anesthesia prior to being killed. Rats(More)
BACKGROUND AND OBJECTIVE Infection of the cerebrospinal fluid is a life-threatening condition which is usually treated with systemic antibiotics and continued ventricular drainage in children. The aim of this study was to analyze the antimicrobial activities of two antimicrobial-agent-impregnated ventricular catheters and to compare their efficacies on the(More)
A number of different techniques are used to treat chronic subdural hematomas surgically. In this study, 70 chronic subdural hematomas were surgically treated and analyzed prospectively. Patients were classified according to clinical features and computed tomography images. Results of the cases that underwent burr-hole craniostomy-irrigation (group A; n=35)(More)
A 67-year-old woman was admitted to our clinic with symptoms of normal pressure hydrocephalus, lower cranial nerve pareses, and pyramidal and cerebellar signs associated with respiratory disturbances. Computed tomography (CT) and magnetic resonance imaging revealed a 4.7 x 5.4 cm quadrigeminal arachnoid cyst causing severe compression of the tectum and(More)
Vascular involvement is common in Behçet's Disease (BD). The venous system is often affected, while arterial system involvement is a rare occurrence. Intracranial aneurysm formation associated with BD is extremely rare. A 38- year-old male patient with BD under the follow-up of the Dermatology department presented with acute headache. The cranial computed(More)
The combination of anterior and posterior instrumentation provides the most stable repair for burst fractures of the thoracolumbar spine. However, the use of both approaches on a trauma patient may increase morbidity. Stabilization of three columns through only one approach can provide an effective outcome. We treated eight patients with burst fracture(More)
SUMMARY In conventional spectrum management, spectrum bands are given to license holders with static policies. As there is dramatice increase in areas of wireless applications, most of the users have problems to find spectrum bands to operate on while most of the spectrum bands are not utilized. Cognitive radio is a tecnology which is proposed to solve this(More)
OBJECT This is an investigation into the effects of two barrier membranes in the prevention of peridural fibrosis in an animal model. METHODS Seprafilm or Gore-Tex was applied to a laminectomy defect overlying the dura mater in rats separated into treatment groups. A third group of rats underwent laminectomy only and served as controls. Two months(More)
