OBJECTIVE The complement system is thought to play a major role in initiating some of the inflammatory events that occur during reperfusion injury. The aim of this study was to assess the effects of C1 esterase inhibitor (C1-INH) on ischemic injury in the rat model of middle cerebral artery suture occlusion and reperfusion. METHODS Thirty-six male Wistar(More)
The authors describe a case of glioblastoma multiforme (GBM) associated with previous gamma knife radiosurgery for a cerebral arteriovenous malformation (AVM). A 14-year-old boy had undergone radiosurgery for an AVM, which was performed using a 201-source 60Co gamma knife system at another institution. The maximum and margin radiation doses used in the(More)
BACKGROUND Spinal intramedullary ependymal cysts are extremely rare. Only seven pathologically proven cases have been reported in the literature. METHOD We present an 18-month-old female with thoracic spinal intramedullary ependymal cyst that was diagnosed pathologically. RESULTS Histological diagnosis was made by light microscopy after immunostaining.(More)
OBJECTIVE Inflammatory processes have been implicated in the mechanisms of reperfusion injury. The migration of leukocytes into ischemic tissue on reperfusion, which involves binding to the intercellular adhesion molecule (ICAM) of the endothelial cell, is thought to exacerbate tissue injury. The aim of the present study was to assess the effects of an(More)
BACKGROUND Despite the current interest in thrombolytic therapy for acute stroke, ischemia-reperfusion injury remains a potentially hazardous complication. The complement system is thought to play a major role in initiating some of the inflammatory events occurring in the reperfusion injury. This study was conducted to explore the effect of C 1 esterase(More)
We evaluated the activity of dilator nasalis+ EMG (Electro-Myo-Graphy) and submental EMG during sleep in three patients with obstructive sleep apnea syndrome. Both EMG activities involved periodic changes which proved to be correlated with each other (r = 0.85). Apnea and hypopnea episodes always occurred at the nadir of these periodic changes. The activity(More)
