BACKGROUND The present randomized, placebo-controlled, double-blind study was designed to assess the effect of peroperatively administered i.v. magnesium sulphate on anaesthetic and analgesic requirements during total i.v. anaesthesia. METHODS Eighty-one patients (36 women, 45 men) undergoing elective spinal surgery were included in one of two parallel(More)
Damage which occurs following spinal traumas is often irreversible. During recent years free oxygen radicals formed due to the pathological changes following neural tissue ischemia have been identified as being responsible for the ethio-pathogenesis of such damage. In our experimental study, model lesions are formed in spinal cords of rats by standard(More)
A case of gliofibroma occurring in an adult patient as a large circumscribed supratentorial tumor is reported. The bimorphic pattern was substantiated and further analyzed by immunohistochemistry. Some evidence in favor of collagen production by mesenchymal and/or inflammatory cells leading to a progressive fibrous replacement of the glial cells in this(More)
Most of the numerous experimental studies to research pathophysiological changes following acute spinal cord injury suggest a two-step mechanism of damage to the spinal cord in which the primary (direct) or mechanical injury caused by the trauma initiates secondary (indirect) or progressive autodestructive injury of the cord. During recent years, free(More)
BACKGROUND Risks related to rebleeding of a ruptured intracranial aneurysm have decreased. However, ischemic neurologic deficits related to vasospasm are still the leading causes of mortality and morbidity. It is well known that vasospasm is a dynamic process affected by various factors. The severity of vasospasm in animal models and clinical observations(More)
BACKGROUND We investigated the individual and combined effects of magnesium sulphate, which is an N-Methyl-D aspartate receptor antagonist (NMDA), and z-LEHD-FMK, which is a caspase 9 inhibitor, on the genesis of secondary injury in a rat spinal cord injury model. We aimed to minimize the effects of secondary injury in spinal cord trauma by choosing these(More)
The sympathetic trunk is sometimes damaged during the anterior and anterolateral approach to the cervical spine, resulting in Horner’s syndrome. No quantitative regional anatomy in fresh human cadavers describing the course and location of the cervical sympathetic trunk (CST) and its relation to the longus colli muscle (LCM) is available in the literature.(More)
We examined the effects of gemcitabine, a novel nucleotide analogue, and vinorelbine, a semi-synthetic vinca alcaloid, in C6 glioma cell culture. We simultaneously monitored the modulation of its activity in combination with the telomerase inhibitory agent dimetilsülfoxid and with a specific cyclooxygenase-2 inhibitory agent Rofecoxib. The effects of the(More)
OBJECTIVE In many pituitary tumor, immunohistochemical studies have been shown to be correlated with different aspects of tumor behavior.There is no study up to date in which markers of Ki-67, p53, VEGF were evaluated concomitantly in GH-secreting adenomas.This study aims to determine which marker has a major role in tumor behavior and whether these markers(More)
OBJECTIVE To evaluate the clinical outcomes of patients with lumbar disc disease undergoing fully endoscopic surgery at a single clinic. METHODS Between August 2009 and January 2012, 163 patients (74 men and 89 women) underwent fully endoscopic lumbar discectomy. All patients were followed for 1 year after surgery. The Oswestry Disability Index and a(More)
